50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.
because all over the world there is an standard rate of voltage
The three generated waves in three phase are spaced 120 degrees apart.
yes it can
Phase voltage is equal to the line to line voltage divided by root 3 or 1.732. So 440 L-L/1.732 = 254V. Your phase voltage is 254V.
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
Use a transformer. A 208-240v single phase line has 2 power leads. Consult your local electrician for help! 440v systems are not for toying with when questions like this are asked.
For the same power - Watts - you need to run twice as many amps at 220V than at 440V. For the same load, it'll pull half the amps at 220V than it did on 440V
in 3 phase motor u1,v1,w1 give to the short terminal and remaining v2,u2,w2 give t0 the in coming power supply of 440v
Well that is probably a very complicated circuit. You should just look for a Inverter with 220V single phase input and 415V three phase output. It should be that hard to find.
