A balanced 120/240-volt single-phase service calculation totals 28,800 volt-amperes. What current does that represent at 240 volts?

A60 amperes
120 amperes
C240 amperes
D6,912 amperes

Why B is correct

For the balanced service total, divide apparent power by 240 volts. Twenty-eight thousand eight hundred volt-amperes divided by 240 volts equals 120 amperes.

A calculated 120/240-volt single-phase service load is 38,400 volt-amperes and is balanced across both legs. What current does it represent at 240 volts?
A calculation step has 18,000 volt-amperes subject to a stated 65-percent demand factor. What demand load is carried for that step?
A service calculation contains 84 amperes of noncontinuous load and 32 amperes of continuous load. Ignoring other demand factors, what calculated current results?
A 208-volt three-phase transformer delivers 125 amperes at full load. Using 1.732, approximately what kVA rating does that represent?
A demand calculation carries 31,500 volt-amperes after applying a stated 75-percent factor. What connected load existed before that factor?
A service calculation is limited to 146 amperes and already includes 96 amperes of noncontinuous load. With the remainder carried at 125 percent, what continuous load can be included?
