What Causes Your Circuit Breaker to Burst

Circuit Breakers are electrical components designed to protect us against the risks of electric shock and our homes against fire and other types of damage that can be caused by electrical faults. Each circuit breaker in your electrical switchboard usually protects one or more related circuits against overload, short circuit and earth leakage.

In order to understand what causes a circuit breaker to burst (or more commonly known as trip), we first need to understand what a circuit is and what the terms overload, short circuit and earth leakage mean.

What Are Circuits?

The electrical installations in our homes are divided into electrically separated segments known as circuits. Each circuit provides electricity to equipment in a very well defined and specific group. All the light fittings and light switches are found on one circuit known as the lighting circuit. Air-conditioners, heating and ventilation equipment are grouped on another circuit known as the HVAC circuit. And last but not least, socket outlets are grouped on a circuit known as the power circuit.

Each circuit is made up of cables, switches, connections and other electrical equipment designed to carry only the maximum electrical current specified by the manufacturer. When exposed to current exceeding this maximum, the electrical component may break down, melt or catch on fire. Circuit breakers were introduced to ensure this does not happen by disconnecting the electricity supply when the electrical current that flows exceeds the maximum capacity that the circuit components can handle.

Overloaded Circuits – The Main Reason a Circuit Breaker Trips

Have a look around your house at all the socket outlets. How many appliances are plugged into each socket outlet? Chances are you’ve got more than the circuit is designed for. Our increasing use of electrical and electronic devices puts more pressure on our electrical installations every day – sometimes to the point where the amount of electricity we use exceeds the amount that the circuit can safely give us without overheating or getting damaged. When this occurs, the circuit breaker in your switchboard will disconnect the circuit from the electrical supply.

Short Circuits – When Things Go Really Wrong

Whether you’re digging in the garden for the great new flower box, or drilling a hole in the wall to put up that lovely family picture, each time you make changes to the house you run the risk of damaging electrical cables concealed behind walls or in the soil. When you drill a hole through a cable or cut it with a spade, direct contact occurs between the individual wires in the cable. This is known as a short circuit. Electrical cables aren’t designed to withstand the current flowing in such a short circuit situation. In cases such as this, the short-circuit protection mechanism in the circuit breaker disconnects the electricity supply to ensure that the cable does not melt or catch fire.

Earth Leakage Currents

Sometimes known as ground fault current or residual current, this is electricity that flows from the electrical installation to the ground or other conductive materials of the house. Electrical systems are designed to pass current between the live conductors of the installation. When appliances like kettles, refrigerators and washing machines become faulty, they can allow current to flow through their metal parts into your body and down to the ground. This is a dangerous situation known as an earth leakage. Certain types of circuit breakers known as Residual Current Devices or Ground Fault Current Interrupters trip when they detect this current flowing to the ground to protect you from electric shock.

In summary, there are only 3 very simple reasons why circuit breakers trip:

1.) A circuit is overloaded, i.e. there are more devices connected to it than the circuit can actually accommodate.

2.) A short-circuit is present. Although less likely than an overload, a cable or other part of the fixed wiring may be damaged. You’ll need a qualified electrician to repair this fault and make your home safe again.

3.) An appliance is causing an earth leakage current to flow. Of all the scenarios, this is by far the most likely cause. Appliances become faulty all the time, and the result is a circuit breaker that keeps tripping.

What should you do if your circuit breaker keeps tripping?

Contact your local electrician to help you find out what the cause is. If you’re from Perth, Western Australia, contact a Perth electrician or one of the Perth electrical contractors.

Qualities Of A Good Window Cleaning Service

In any building whether business or domestic window cleaning is a basic expense. This is due to the fact that most buildings are made of steel and glass. Glass under a considerable duration of time accumulates dirt which mandates the need to clean them. There are some traits of the cleaning service provider that you should consider when choosing one.

One trait is reliability of the company. Therefore, the company you go for should have experience in commercial and residential cleaning. You should companies that commonly send their trainee staff, because the risk of damages and losses are high. With that, you need to check the credentials of the company so as to get information on their experience. The need for an experienced company is because they usually use professional cleaning tools thus satisfactory results given.

Another trait is that the workers of the company should insured and bonded. If the firm’s employees are insured, this means that the employees are covered in the case of accidents or damages while working. If they are bonded this means that in the case of the workers stealing anything in your premises then company has covered you from this. The benefit of checking whether the service provider has these covers is that the company will be able to compensate you.

Thirdly, you should check on the trustworthiness of the service provider. Trust comes in because most people usually have their windows cleaned when they are not in their business premises or at home. Therefore, a trusted company should be hired so as to ensure that your property is safe. Even when you are around checking on them there is a high probability that you may leave for a couple of minutes and if you did not check on their trustworthy, you will end up being robbed.

Also check on a company’s cleaning equipments by checking whether they are well equipped. In the case, where they are working from inside, they should have shoe covers on. They should also have ladders to be able to reach hard to reach heights. This is in the case if you have very high windows that one needs to step on something to reach them.

The company’s cleanliness should be another trait you look at. Appearance should speak for the company’s effectiveness. If the company is dirty then how will they manage to clean at your place? Apart from checking their business premises also check on their vehicles. Check whether they are clean and labeled. It is ironical to hire a cleaning company that cannot clean its own premises.

The company should be reputable and recognizable. Therefore, the company should appear in the business bureau. Also, by asking around you can easily check on the client feedback on the efficiency of the services. You will be able to get the reputation of the various companies and go for the one with the best reputation.

To sum it all up, choosing a window cleaning company is not an easy venture. You should always note that not all companies out there are genuine. Following the tips given above you will surely get the best cleaner for your needs.

Cockroach Pest Control in Abu Dhabi and Dubai

Cockroach control is one of major task for pest control services There is a carefully kept secret (companies who deal with chemical pesticides have done a great job of covering it up): What those chemicals do to those pests is what they also do to human beings. These chemicals are largely to blame for many instances of certain health conditions. Among them include immune and neurological disorders, Alzheimer’s, certain types of cancer, certain birth defects and Hodgkin’s. Those chemicals attack the nervous systems just in the same way they do those pests.

From a recent study it has been known that the janitorial services are not absolutely dominated by companies. Rather there are private organizations run by some general people. All the janitorial firms are private and they take care of the contracts made with them by the companies.

If you do get some small bugs, try spraying a simple soap solution: 40 parts water and one part non-detergent soap, such as Ivory. Spray the bottoms of a few leaves first, to make sure it will work on specific plants. If it seems to work without damaging the plant, then a few moments after you use it each time, rinse it off. This can eliminate many fairly ordinary pests.

Repair any leaky pipes and other plumbing issues around your home. For the sake of pest prevention, do not allow any water to accumulate or sit for extended periods of time in your home. This can usher in mildew and mold problems as well. Empty the tray under your refrigerator frequently as well as the trays under any house plants that you might have. The more you can do in the way of pest prevention the less you have to do in the way of rat control, bed bugs pest control!

Pest Control in Sharjah

I was quite excited to have stumbled upon this very-well camouflaged nest. I went back about a week later to find the nest empty. But what a great experience I had had! Now I find myself listening for their loud call in late Spring. They return every year to entertain me with their antics.

When dealing with the creepy crawlers, its perfectly fine to admit that you’d rather not do the job of killing them all yourself. And that you’d rather pay someone else to do it for you. Or, you just don’t have the time and don’t want to suffer the inconvenience of doing this yourself. This is what pest control companies are for! Just pay them a moderate sum, and the pests will all be removed from your life!

Know Different Types of Tile & Stone Installation

You dream to be the owner of a building that is picture-perfect, as well as, versatile. You want it to counter the ravaging influence of time. If you are genuinely interested in making an ultimate statement, then, you have to choose the tile and stone installation. The material base lends a timeless durability to structures. Apart from this, such installations also stand out, on account of their grace and natural beauty.

Endless options to choose from

The category includes plenty of options. You can make your pick from the ceramic, porcelain and glass tiles. As far as the stone-based installation is concerned, you will not run short of options that are unique, appealing and natural. Just as you can choose marble or granite, similarly, you can use travertine to come up with a long-lasting designing solution.

Things that you should know

It is important that you are aware of the features and finishes of the different types of stone and tile-based installation. You should know how much to pay for the tile or stone that you have selected. But do remember, installation charge and knowing the cost of materials are not the only aspects to focus on. You should know the maintenance cost, as well. For instance, if you understand that it is easier and more economical to maintain tile than installations based on stone, then, you can take a useful decision.

Know the performance of each installation

Product performance of individual installation varies according to the density. Porousness and glaze also affect the net performance and durability. Granite, as well as marble, is denser than the other varieties of stone. So, if you have to choose between these and travertine, you should vote for the former. With their greater density, they impart solidarity and permanence to installations. Just as you need to study the hardness level of different types of wood while selecting wooden furniture, similarly, you should know which stone type is denser than the other. Only then, you can assess the performance potential of different installations.

Different types of tiles

While researching the tile and stone installation, you have already noted that tile is more cost-effective to manage and maintain than stone. So, you are looking for one of the best varieties of tile. In this context, it is worth noting that different varieties of tiles are rated differently. Flooring experts categorize different varieties according to their abrasion resistance and overall durability. The rating comes on a scale of one to five. Both porcelain, as well as, ceramic tile is rated highly because of their durability and resistance to abrasion. Glass tiles are not rated that highly. You now know the reasons that are responsible.

Constructional differences are also there

Ceramic tiles of the glazed type are made of earth materials. But since the porcelain tile happens to be the hardest, it is used across a wide variety of applications. The latter is more popular than the former in the constructional industry. Glass tiles come in different textures, sizes, colors, and shapes. The glass-based variety accommodates mosaic configuration. You can use the type to accentuate the impact of your floors, showers, and backsplashes.

What Does Your BMW’s Cabin Filter Do?

Since you have to think about several aspects of your vehicle, you may forget about an important aspect called the cabin filter. If you are not familiar with this part of your car, you are on the right page. In this article, we are going to find out more about the function of the cabin filter of your BMW.

Functions of a BMW Cabin Filter

While driving, you breathe in the clean air because of the cabin air filter. Just like the engine air filter, this one is responsible for filtering dust and debris. The air inside the BMW cabin remains free of dust if the filter is functioning properly.

Apart from this, this component makes sure that the radiator, fuel line and engine is free of contaminants.

Change the Filters

Just like the engine filter, you may want to replace the cabin air filter on a regular basis. If you don’t change it for a long period of time, it will have a negative impact on the HVAC performance and your comfort level while driving.

Apart from this, not replacing this filter will negatively affect the air conditioning system of your vehicle. As a result, you will have the problem of poor HVAC performance and increased allergens. Besides, you may find it difficult to defog your Windows.

Signs You Need to Change the Cabin Filter

Based on the model of your BMW, you may want to replace this filter after 12000 miles. As a general rule, you may want to replace this component at least once a year. However, you may want to consider a lot of factors to make this decision. The frequency of changing the filter will be higher based on road conditions, driving habits, and the condition of the HVAC system, just to name a few.

If you notice that the air conditioning system is not working properly, chances are that you need to replace the filter.

Other Signs to Watch Out for

If you notice reduced airflow in your cabin even if you turn up the fan, chances are there the filter is clogged. Besides, if the HVAC system produces nasty odors or you hear a whistling sound from the air intake, or your HVAC system is not producing enough cool air or hot air, you may want to check this part and replace it.

It is important to note that if you drive in extreme temperatures, such as a desert, you may want to replace the cabin air filter more frequently. In the same way, if you drive through polluted areas on a regular basis, it will require more frequent replacement.

The Takeaway

If you want to get the most out of your BMW, we suggest that you take care of regular maintenance. This includes replacing cabin air filters, engine flush, breaker display replacement, and oil changes. Hopefully, now you understand the importance of this part of your car. You may want to replace this part on a regular basis to ensure the proper functioning of your HVAC system.

What Type of Air Filter Is Best for Your Air Conditioning Unit?

There are many different types of air filters and air conditioning cleaning systems used to not only filter the air in your home, but also protect the often costly heating or cooling equipment used to protect and maintain your unit. In this article we will cover some of the different types of air filters, and cleaning systems available to consumers.

Before we get into the details about air filters and air cleaning systems, It’s important to understand why having a high efficiency air bear filter is so important. Most people are very surprised to find out that the air inside your home or apartment is far more contaminated and polluted than the air you and your family breath outdoors. We are taking about the air you and your family breath on a daily bases most of the time. The indoor air that you and your family breathe can be contaminated with micro-particles such as dust, smoke, and lint. In many homes, pet dander, mold, and bacteria, complicate the problem even more. In fact, 99% of the particles circulating in your home or apartment air are one micron and smaller which is less than 1/40th the diameter of a human hair. These micro particles can aggravate your allergies, and irritate your respiratory system or simply make your home or apartment dusty and dirty.

The most common air filter that you would find at a hardware store tend to be very basic only capturing very large particles, therefore not protecting you from the more dangerous contaminates floating through the air and eventually your lungs. The first step to moving toward cleaning the indoor air in your home is to pay attention to the MERV rating of the air bear filter in your unit. A national organization, ASHRAE, developed the standard for testing air filters. With this test, the results are expressed in MERV (minimum efficiency reporting value). Simply stated, the higher the MERV rating, the more efficient the air bear filter will be in removing contaminants and pollutants from the airflow. It is always best to try and find a air filter that fits your unit with the highest MERV rating available. If you would like to take it one step further, you can have a system added to your unit that uses HEPA technology, however this solution is often very expensive, and the replacement filters are also very costly. While HEPA filtration is very effective it is often times not necessary. Always be sure to choose an air bear filter with the highest MERV rating available.

5 Ventilation System Maintenance Services You Need

In a number of different types of premises, the owner or the management company is responsible for the statutory inspection and maintenance of smoke and mechanical ventilation systems. This is to ensure that the system is working as well as it possibly can in order to provide a safe environment for occupants.

With maintenance and inspection such a large part of the responsibility that building owners have to bear, it is often a good idea to invest in a ventilation system maintenance service, as this will keep the premises in line with statutory requirements as well as identify and repair major problems in the system as early as possible; here are five services that are definitely worth investing in.

Firstly, look for a ventilation maintenance company that will help the building owner or manager establish service logs and test schedules in order to make sure that all statutory requirements are met in a timely fashion.

Making sure that this test schedule is adhered to and that the log book is kept up to date will ensure that smoke and mechanical ventilation systems are compliant and that occupants are safe. It will also mean that fire fighters will have easier access to the fire fighting lobbies and shafts in the case of an emergency.

A second service that is worth having is one that can supply spare parts and make repairs on a rapid basis. Many of the best ventilation installation companies out there have a huge range of ventilation equipment in stock, meaning that if any problems are detected they can be remedied quickly and easily.

This leads on to the third service that is highly recommended, and this is a 24 hour emergency callout service. All types of ventilation system can fail, and in many cases it is urgent to deal with these issues in order to have equipment up and running quickly. This can be especially important in areas where occupant safety is of paramount importance, such as in hospitals and schools.

Having a reliable company on hand that can travel out to repair problems in equipment is arguably a necessary component of responsible building management. When the company also has all the necessary replacements in stock to fix the issue in an instant, this is even better yet again.

Fourthly, look for a service that carries out preventative maintenance visits on a flexible timescale. This latter point can be very important, as in some buildings it may not be possible to carry out maintenance at certain times of the day.

A schedule of preventative maintenance visits should be established between the ventilation installation company and the manager or owner of the premises, as this will avoid the frequent need for emergency callout services; preventing issues from occurring in the first place is far better than trying to repair damage once it has been done.

Lastly, search for a ventilation installation company that can provide ongoing technical support and friendly advice whenever it is needed the most. Although some companies charge extra for this kind of service, many offer all-inclusive packages that mean that all questions can be answered by an expert in a timely and precise manner.

This can be very helpful if there is an issue with a smoke or mechanical ventilation system that the building owner is unsure needs repairing or not, or if the building manager has an important question about completing the service log or statutory requirements.

These are just five of the most essential components of a quality ventilation system maintenance service. As maintenance is required by law, it is in many cases worth relying on the experts to help building owners adhere to regulations much as possible to ensure the safety of their premises and all the occupants that are living, staying or working there.

5 Must-Haves for Today’s Commercial Office Space

How should an office space be for employees to be more productive?

Should it be in a metropolitan location? Should the space have all the facilities provided?

What are the amenities one would look for when looking for an office space?

Well, if you aren’t actively involved in finding sourcing and leasing commercial office space, the process of finding the right office can be more challenging. Little details can make a big difference in your space occupancy, after all. Once you’ve figured out your budget, here are few things to watch for.

1) Good Environment

Good environment doesn’t mean you have to add some super-lavish furniture elements to make it attractive to your employees. Sometimes, proper ventilation adds a great beauty to the office space location. You can also play with interiors and wall decors to make it more interesting place to work.

2) Reasonable Commute Options

Yet another important thing is that companies should be concerned about while choosing a commercial space is the commute options available for the office space location. It’s good to have office space in a location where the employees can reach without any difficulty.

No one wants to travel for a very long distance with no facilities provided to reach office easily. Sometimes, difficulty in commuting can also be a reason for an employee to think of switching the other company. So, companies should either provide cab facilities to employees or consider having their office in a location that has frequent transportation so that the employees can reach office very easily.

3) Good Parking Ratio

Every office space should have a dedicated parking space to park the vehicles. When the mobile workforce increases, employees will obviously have to get their own vehicles to the workspace, and they want their vehicle to be safe.

So if you’re looking for an office space, consider choosing the office space for the business that has good parking ratio, so that the employees can park their vehicles without having to fear about damage, theft or any other mishaps.

4) Proximity to the Amenities

Closer the office is to amenities like coffee shops, restaurants and hospitals, easier it will be for your employees to do what they need to. Employees should need these amenities for a great hangout place to spend their free time and relax along with their friends or teammates. Along with amenities, it’s a good option for an office to be located close to services that the business needs.

5) Good Structure and Utilities

Last but not the least; you should also see if the office building offers other utilities to support your business objectives. So, make sure that the building’s electricity, power backup, water supply and ventilation systems are up to the current standards.

Also, see if the building is structurally sound enough from foundation to roof and consider if you have to make any structural changes on the space.

Overview of Thermostats and Advanced Air Conditioning System Controls For AC and Heat Pumps

Thermostats: Tools That Manage HVAC Performance

In basic definition, thermostats and advanced A/C system controls function as simple on/off switches. The switch trips whenever changes in the indoor air temperature of a structure nears the associated thermostat’s set point. But modern HVAC performance involves much more the simplicity of an on/off thermostat control function.

The following overview reviews the power of thermostats and advanced A/C system controls.

Basic Thermostat and A/C System Control Processes

In 1883, Warren S. Johnson invented the first electric room thermostat. The Johnson Controls technology used mercury and electrodes inserted directly through the glass. The systems were accurate within one degree of temperature.

Skip ahead. In modern technology, most 2014 air conditioning and heat pump thermostats operate on low voltage control circuits that pull 24 volts AC from a control transformer installed within the home’s heating or cooling equipment. Low voltage control technology provides a safety advantage that enables the thermostat to operate multiple electromechanical contractors, relays and sequencers at inherently safe voltage. Modern systems also include an integrated “anticipation” function that activates the contacts in a manner that prevents room temperatures from overshooting the desired temperature settings. And all this excludes the growing range of features associated with modern programmable thermostats & controllers.

Pre-digital Heating and Air Conditioning Thermostats

In 1953, Honeywell introduced the T-86 “Round” thermostat technology. This bimetallic-spring regulated room thermostat still controls millions of home heating and cooling systems throughout the world.

Typically mounted on a central wall within the home, the traditional Honeywell thermostat uses a basic dial-type round-controller design that includes two temperature scales and two temperature pointers. The top scale and pointer provides the adjustable components of the system. The bottom scale shows the actual physical temperature in the chosen area of the home. Rotating the pointer in the top scale to the right increases the desired heating requirements. Rotating the pointer in the top scale to the left decreases the desired temperature setting.

In the early years, thermostats designed to control both cooling and heating included a manual setting switch at the base of the unit. This switch, also seen in rectangular units of the pre-digital era, can be moved from heat-to-off-to-cool or back again. The temperature sensor within the units compare the air temperature near the thermostat to the settings of the system and turn on or off the associated heating or cooling equipment as appropriate. The heat/cool/off control switch assures that only the selected equipment can activate at any one time.

Digital Era Thermostats and Controllers

By the year 2005, nearly 97% of U.S. households used installed heating systems. During the same time frame, only 75% of the U.S. households used air conditioning. But the world is changing and the changing climates associated with global warming continue to press upward the demand for installed air conditioning.

Modern programmable thermostat and controller technology bestows a dramatic increase in features and capabilities. From simple on/off heating and cooling to controlled ventilation systems and from manual settings to controllers that respond to electricity price-signals the home air conditioning and heat pump management system engages in a whole new arena of thermal comfort and energy savings.

And then along come thermostats and advanced air conditioning controls that link directly into the home Internet networking system. Wonder what comes next?
