0.
1. Set to 3-Phase:
(3Ø)
3Ø 3 PH
2. Enter VA:
VA 8,250.
3. Enter Volts:
VOLT 240.
4. Solve for Amps:
AMPS 19.846416
Finding Current Load
A building with 120/240 Volt 1Ø service has the following loads:
Range = 7,800 VA Heating = 15,100 VA
Dryer = 5,100 VA Appliances = 8,900 VA
Lighting = 6,470 VA
What is the service load (Amps) of the circuit supplying this building?
