Commercial buildings require special considerations when it comes to electrical wiring. Most commercial buildings do not have the luxury of a wooden frame to run wires through, so other wiring methods must be used. Some of those are discussed below.

In some instances, armored cable may be used. This type of cable, known as teck cable, is available in nearly any size and features a core made of the desired number and sizes of wires, protective jacketing, flexible aluminum armor, and in some cases a weather-resistant exterior jacket. Teck cables can be pulled through conduit, cable tray, or be buried directly in the ground as long as the cable is rated for direct burial and certain burial depths are adhered to. Teck cables can also be installed in hazardous locations by using special explosion-proof cable fittings and approved sealing compounds. The main advantage to teck cable is its ease of installation and versatility. When using a cable tray system, cables can also be easily added or removed at any time.

With this basic knowledge of the types of electrical wiring methods used in commercial buildings, it is easy to select the best option for any installation.

Across the country this week students strapped on their backpacks and headed out for an exciting new year of school. But in the midst of that back-to-school glee, one word still strikes fear in both parents and students … Homework. What if there was a way to make the homework battle less stressful, dare I say enjoyable? Today I’m sharing five dread-busting homework stations with creative lighting that may actually make your student want to do homework.

A safety switch is essentially a device that very quickly switches-off the electricity in case any electrical fault is detected. In effect, it reduces the risk of injury & death caused by contact with electricity. Current day safety switches are very different from the ones used even up until a decade ago. Today, it’s mandatory to have these installed in buildings where any kind of electrical addition or upgrade has taken place.

Apart from this, safety switches are also needed for power outlets that that supply electricity to mobile homes like caravans etc. It’s not mandatory to have these safety switches in older homes; however, the recommendation is that you should consider getting them installed. It is one of the most effective ways to protect your family & yourself from electric shock.

ELCBs or Earth-leakage circuit breakers are safety devices used to prevent shock in electrical fixtures which have high Earth impedance. The current installations use the circuit breakers that directly detect leakage in current. Here are some features of an ELCB:

RCDs or RCCBs are essentially modern electrical wiring devices which quickly disconnect a circuit if they detect that there is an imbalance in the current between the energized conductor/s & the return conductor. They are designed to immediately switch-off the electricity supply when the electricity leaking to earth is detected to be at harmful levels. These devices offer very high levels of protection from electric shock.

Voltage Earth-leakage circuit breakers were first introduced around 60 years ago, while the current ELCBs were launched only around 40 years ago. For a very long time, voltage-operated ELCBs & differential current-operated ELCBs were both called ELCBs; this was because it was a far easier term to remember. However, as expected, this common name caused a significant amount of confusion within the electrical industry.

If someone accidently used the wrong one in a particular application, the installations may not get the kind of protection it needed. It was to eliminate this confusion that the International Electrotechnical Commission decided that the differential current-operated ELCBs will be termed as RCD (residual current devices). Any current that’s over & above the load current is referred to as the residual current.

ELCBs have a number of disadvantages such as:

Today the RCD is preferred means of providing effective shock protection. The term is also most widely used across the globe.

There are a number of times when homeowners take up DIY projects; not only do these help you save money, but many people find the idea of doing some of this work around their home, extremely fulfilling too. While it’s okay to do some carpentry or painting work, it’s best to leave electrical jobs to the experts; and there are a number of reasons for this.

Many people feel that they may be able to handle some basic electrical jobs themselves; but the fact is that electrical systems and installations can be quite complex and it’s not easy to tackle them. Apart from this, it’s required by law that you hire a licensed and insured electrician for any work on your residential or commercial premises. Take a look at how and why DIY electrical jobs can do a lot of harm:

There are a number of wire sizes available; this is called the gauge of the wire and this determines the application it’s going to be used in. If you accidently choose and install the wrong wire, this can cause it to heat up and the circuit breaker may trip. This is why it’s important to use wires and devices that are rated correctly for the amperage that’s required in a particular location.

If the switches and outlets have been installed loosely, that can present a hazard once the appliances have been plugged in. If the wires come loose from the terminals, that can result in overheating and arcing.

The reason for an electrical box installation is to provide the connections the right amount of protection from the external elements. This is also why it’s extremely important to ensure that no electrical connections are made outside these boxes. The other thing to keep in mind is that the electrical boxes should only be filled to a certain capacity. Adding too many wires and connections in a single box can result in overheating; in some cases, it can also result in short circuiting.

This happens to be one of the most common causes of electrical fires. When fuses keep tripping or blow, property owners may end up replacing them with breakers or fuses of a larger size. If a fuse trips very regularly, it’s first crucial to identify what is causing it to trip; that root problem has to be addressed by a licensed and insured electrician.

The connections inside the fuse box should all be tight and when they are replaced, the positioning should be right. In case the connections come loose, you might find the lights flickering or being cut short. In severe situations, there could be overheating of the connections too. The precaution to take here is that before you start with any inspection, you should first switch off the breakers.

This is one mistake that many people tend to make; they end up overloading the powerboard or the outlet. It’s important that you check how many amps a circuit can bear and then plug in only the type of appliances that aren’t going to overload the board. Appliances such as air conditioners, dishwashers and refrigerators etc. can overload the circuit, if it exceeds the amperage of the board .
