There is no obligation. It is recommended to employ commercial electricians. Installation of electrical lines is an extremely difficult and complicated task that requires a lot of electricity.
Here’s what goes through an underground electrical services company for commercial properties:
Underground electrical wiring runs from the power poles, through white conduit, and then into the ground.
Underground wires are attached with the transformer. When the transformer is shut, the wires pass through the conduits and into the structure. Inside the building, the underground wires are then buried in a conduit of plastic, and eventually into an electrical disconnect on this commercial structure.
From the disconnect, in this case, the 600 volts, 3 phase 400amps disconnect. Electrical wires go across the CT cabinet, starting from the disconnect – an integral part of an electrical metered system. Commercial buildings are exposed to high voltage and amperage levels. A CT cabinet is required due to the fact that it needs to be metered.
From within the CT Cabinet, it then goes through the electrical panel wherein it makes use of all the power supplied through the transformer from the power poles. It then goes through another transformer from the electrical panel that will feed the entire electrical power into the commercial property.
