You use it every day, but do you really understand electricity? It’s important, because, without understanding electricity, it’s hard to maintain electrical safety in your home. In order to understand electricity, you basically need to grasp five key concepts; we like to call them the five hidden mysteries of electricity.

Up/Down LED Panel Light that provides usable downlighting and ceiling accent lighting simultaneously. Without any visible bulbs, this dimmable light panel delivers 5,400 lumens of natural white illumination through a transparent lens with a frosted center. The LED panel lasts five times longer than fluorescent panels and can be used for many applications, including suspended office lighting, pool table lighting, restaurant lighting, decorative or painted ceiling illumination, and retail shop lighting.

There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion.

Forget colleges and engineering schools, most high school students learn that electricity does behave this way, as a part of the basics of electricity and resistances. Worryingly, this myth isn’t just stated as a fact, it’s a commonly followed practice in many electrical circuit designs, especially when it comes to grounding.

Walk into any industrial plant that uses motors or pumps and you’ll find they’re all connected to ground rods. Ask anyone why that’s done and you’ll likely get the same response everywhere (even from the people in charge of the electrical maintenance) – It’s to eliminate the potential differences.

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.
