Given: Transformer is 150 kVA, transformer existing load is 220 amperes per phase; and voltage is 208Y/120, 3 phase. What approximate additional single-phase load per phase may be added to the transformer?

1) 180 amperes

2) 196 amperes

3) 416 amperes

4) 501 amperes

The line current for a 208/120-volt, 3-phase, wye system, if each phase is balanced with a 2,500 VA load and the total load is 7,500 VA, is ____ amperes.

1) 12.01

2) 20.82

3) 36.05

4) 40.00
