100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V… Read More

### Why is 1 phase 240 volts and 3 phase 415 volts?

In a three-phase, star- (or wye-) connected, system the line voltage (line-to-line voltage) is 1.732 (or the square-root of 3) times the phase voltage (line-to-neutral voltage). The reason for this is that a line voltage is the vectorial sum (not algebraic sum) of two phase voltages displaced from each other at 60 degrees. These days, incidentally, the UK's nominal phase voltage is 230 V, and its corresponding line voltage is 400 V.

Three phases are: 115 volts @ 0 degrees 115 volts @ 120 degrees 115 volts @ -120 degrees Just for comparison purposes, phase to neutral voltage is: (Phase) - (neutral voltage) = (Phase) - (0) = Phase voltage So phase to phase voltage is: (Phase 1) - (Phase 2) = (Phase 1) * sqrt(3) = (115) * 1.732 = 208 volts.

### How many ampere do you get in 5000 watts per phase in 3 phase 380 volts?

Do you mean 'per phase' or do you mean 'per line'? The conductors that connect a three-phase supply to its load are called 'lines' not 'phases'. If you mean 'per line', and the load is balanced, then you can manipulate the following equation to make the line current (IL) the subject: power = 1.732 EL IL (where EL = line voltage = 380 V) If you really DO mean 'per phase', then it's necessary for… Read More
