Just FYI, here are some 3Ø Voltage Equivalent values, for use when performing Power related equations:
- 200V = 346,
- 208V = 360,
- 230V = 398,
- 240V = 416,
- 460V = 797,
- 480V = 831,
- 575V = 996,
- 600V = 1039
Take the Line-To-Line Voltage for a 3Ø application, and multiply it by the Square Root of Three (* 1.732)
If the load value is to be figured across only Single Phase Circuitry (L-L ,or L-N), do not use the Three Phase Voltage values listed here - simply use the L-L or L-N Voltage value as applied.
Examples:
208Y/120V 3 Phase 4 Wire System.
A: (1) 10 HP, 208V 3 Phase Motor,
B: (1) 5 HP, 208V 1 Phase Motor,
C: (1) 1.5 HP, 115V 1 Phase Motor.
Volt-Amps for the following Motors:
A: (1) 10 HP, 208V 3 Phase Motor:
11,088 VA* 30.8 Amps at 208V 3 Phase 3 Wire
* 30.8 x 360 = 11,088 VA
---------------------------------------------------------
B: (1) 5 HP, 208V 1 Phase Motor:
6406 VA* 30.8 Amps at 208V 1 Phase 2 Wire
* 30.8 x 208 = 6406.4 VA
---------------------------------------------------------
C: (1) 1.5 HP, 115V 1 Phase Motor:
2300 VA* 20 Amps at 115V 1 Phase 2 Wire
* 20 Amps x 115 = 2300 VA.
