As an electrician, there are two different systems that can be used for ungrounded electrical work. These are known as grounding and bonding. High voltage wires, for example, are grounded to the earth to limit the voltage that the system is exposed to in the event of a short or a lightning strike. Anything that is electrical must be grounded to the earth or a surface that is connected to the earth to make it safer for everyone involved. This can be done with structure disconnecting means or with a grounding electrode conductor to a grounding electrode.
If a light switch is not grounded, it can short out during any type of electrical storm or wiring problem, causing a fire or a complete electrical system failure. In addition to grounding, these pieces also need to be covered with surge protection to avoid high voltage transients or impulses. This will protect them from lightning strikes and other power surges. Once this has been completed, there is one more protective step to take.
The metal parts then need to be bonded together, and bonded to the metal enclosure of the system. You should also be careful not to bond these items to electrically conductive materials that might become energized. This, after all, would defeat the purpose of grounding the electrical wires or parts in the first place. You need to install the equipment and wiring in a method that is permanent and offers a fault-current path from any point on the system to the source of the electrical supply. This path should be low-impedance, which will facilitate the operation of devices that are over current, in the event that a second ground fault occurs on the system.
Electrical work can be complicated if you don’t know what you’re doing or what you are looking for. By taking the time to ensure that you’re able to understand what you’re doing and how wiring should work, you’ll have a much safer work environment. Electrical grounding and bonding is essential to the success of the proper functioning of an electrical system. Even though they can seem complicated to those without training, someone who is trained as a certified electrician will understand the importance of proper grounding and bonding as it relates to the electrical systems of the world.
