Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?
3. The three bus-bar conductors in an outdoor sub-station are supplied by units ofpost insulators. Each unit
consists of a stack of 3-pin insulators fixed one on the top of the other. The voltage across the lowest
insulator is 8-45 kV and that across the next is 7-25 kV. Find the bus-bar voltage of the station.
[38-8 kV]
3. The zero sequence current is
times the current in neutral wire.
