Understanding Single-Phase Electric Service

25 May 2021

How many energized conductors supply 240 volts, 200 amp, single-phase electric service?

a) One
b) Two
c) Three
d) Four

Final answer:

The answer is a) One energized conductor supplies 240 volts, 200 amp, single-phase electric service.

Single-phase electric service means that only one of the three phases of a three-phase power system is being used. In this case, the single-phase electric service has a voltage of 240 volts and a current of 200 amps.

To supply this electric service, only one energized conductor is needed. The other two conductors in a three-phase power system are not used in this particular scenario.
