Assume that you have a building with a Main Switchboard (MSB) feeding a Distribution
Panel. If the MSB measured voltage is 480V, what is the approximate minimum voltage
allowed by the National Electrical Code at the Distribution Panel? - CORRECT
ANSWER-466
Assume you have a home with a submersible well pump. The pump is rated 240 VAC,
is wired with #12 AWG conductor (with a resistance of 2.0 ohms/1,000 feet), the pump
draws 10A and is located 200 feet from the home panel, which has a line-to-line voltage
of 240 VAC. What voltage is available at the pump? - CORRECT ANSWER-236
Assume that each of the two units at Diablo Canyon Power Plant is capable of
producing 1,200 MW. Also assume that a home uses only 10 amps of current at 120
volts on average due to load diversity. The number of homes that each unit at Diablo
Canyon can power is: - CORRECT ANSWER-1,000,000
Assume that you have a parallel circuit with a 4 lamp, 60W light fixture, 720 W exhaust
fan, and a 480 W television all connected to a 120 volt source. The total current (in
amps) flowing through the circuit is: - CORRECT ANSWER-12
