WebOct 1, 2004 · Voltage — The voltage to use for your calculations depends on the system design voltage. Thus when you calculate branch-circuit, feeder, and service loads, you must use a nominal system voltage of 120V, 120/240V, 208Y/120V, 240V, 347V, 480Y/277V, 480V, 600Y/347V, or 600V unless otherwise specified (220.2) ( Fig. 1 below). WebFormula for calculating the watts to volt amps S (VA) = P (W) / PF, which means that the apparent power S in volt amps is calculated by dividing the real power in watts by the power factor (PF). It can also be expressed as; Volt amps = watts / PF or VA = W / PF For example,
