Consider a series of residential services being fed from a
single pole mounted transformer. Cite the NEC
a. Each of my 10 residential services require a 200A service
entrance panelboard that is capable of providing 200A of
non-continuous load. How large should my transformer
be?
b. Size the conductors for these service entrances.
Assuming these are aerial conductors on utility poles, which
section of the NEC would you use to ensure your service entrance is
fully code compliant?
c. I am designing a rec-room for these houses, in which will be
six general use duplex receptacles, and a dedicated 7200 watt-240V
electrical heater circuit. The room will also need lighting,
for which I am installing four, 120 watt 120V overhead
fixtures. Identify the number and size of the electrical
circuit breakers needed to provide power to this room.
