Residential wiring

Residential electricians always use wires with heavy sheath insulation so as to protect the homeowners from receiving electrical shocks.

Commercial wiring

Commercial wiring follows a three-phase design. Here, three phase implies two legs running 120 volts and a third leg running 240 volts. This system allows the circuit to bear a higher workload without getting damaged. Due to this system of wiring, the commercial wiring is able to sustain a large number of high powered equipment with a higher voltage requirement. This type of wiring is ideal for offices and business houses. Commercial wirings also have very heavy insulation and sometimes, special outlets are maintained for the sensitive extremely high powered equipment.
