Nomatter what voltage you use; the rated current (amps); or whether you have 1-phase power or 3-phase power; etc you can always compare watts. If you absolutely must think using amps (i.e., 3-phase power [i.e. most of EU, many other countries, and many of Raritan's largest customers in North America]—then this information does not Firstconsider if the breaker was connected to a balanced 3 phase load with 200A per phase. The power (assume 208V-3ph) would be 200A*208V*1.732=72kVA. Now consider the same breaker with 200A line-to-neutral would be 200A*120V=24kVA per phase, times 3 phases=72kVA. 200Amps on each phase is 72kVA whether it is a 3 phase load or P(kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000. I even found that PF is basically phase shift between current and voltage sine. The only thing I don't get is which current and voltage to use here - I have three of each. 3phase power calculator parameters. Voltage (V): Enter the phase-to-phase (\(V_{LL}\)) voltage for a 3-phase AC supply in volts. Current (I): Enter the the current in Amperes (A). Power factor (cosΦ). Enter the power factor of the load. Its between 0 and 1. How to calculate 3-phase power? The 3-phase power formula for active power is: Thus for DC and single-phase AC circuits, the formula to convert kilowatts to amps is: [1] I(A) = P (kW) × 1,000 V (V) The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts. For example, find the current of a circuit with 1 kW of power at 120 volts. I(A) = 1 kW × 1,000 120 V. I(A) = 1,000 W 120. Manythanks .

Jul 28, 2017 at 19:25 \$\begingroup\$ If the thing will work with a single 32 Amp circuit, I'd go with single phase, assuming that 3-phase power is not Figure 1. 32 A single phase plug and socket (left) and 3-phase (right). The single-phase connectors have .
