negative and neutral. Few electrical appliances such as refrigerators, air conditioners and dryers generally need more amount of energy for domestic buildings. In these situations, 240 volts can be supplied with a circuit of two phases.

Commercial buildings have been supplied through wiring design of three phases. This type of design includes three legs which are a large one operating at around 208 volts as well as two small ones that require 120 volts. So,

each leg will be operating at less workload since it can supply more supply of power to electrical appliances being used. The designing will facilitate higher efficiency by allowing big commercial machines to last for a long time.


The technicians need to perform all installations for residential buildings before the drywall which can hide wires and pipes behind the walls. The domestic electricians will do it as maintenances seem to be rare for local settings.
