Residential and commercial electrical wiring are completely different in terms of energy needs, load demands, and equipment setup. They also require different classes of materials and procedures.
Integrity Power and Electric specializes in Commercial and Industrial electrical work. Let’s look at some of the differences:
Residential electrical wiring is always completely covered within sheath insulation. This is meant to protect residents from electrical shock. From a technical aspect, most residential wiring are single phase and 120 Volts, consisting of three wires, positive, negative, and neutral.
For some more demanding appliances, such as air conditioning units, refrigerators, washers, and dryers use a two phase circuit of 240 Volts. In commercial applications this wiring is normally run through conduits or ceiling rafters where it is easily accessible to service. For residential applications, the wiring is normally hidden from view within walls and attic crawl spaces.
