S= (1/1000) UI √3
Where S in kVA; U in V; I in A; hence I= 1000S/ (U √3)
60 amp,120/208VAC, three-phase
You can install up to four 50 amp single phase breakers on one phase of a three phase 200 amp panel, assuming the panel is balanced properly among the three phases. Each breaker will draw 50 amps of current, so be sure to consider the total load on the phase to prevent overloading.
P= (1/1000) UI (cos φ ) √3where P is in kW; I in A; U in V ;hence I= 1000 P / U (cos φ ) √3
100amps
The specifications of the 600 amp 3 phase main distribution panel include its capacity to handle up to 600 amps of electrical current and its ability to distribute power across three phases.
Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
You can't. Currents in three-phase systems are measured in each of the individual line conductors.
The type would be a three phase panelboard. If you are carrying the wye neutral into the service, then it would be a three phase four wire distribution panelboard. Regardless of the style used, it would have to have a minimum 400 amp bus.
In a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.
If you are looking for total load just add the loads together. If you are looking for sizing of a service to feed the loads, factoring is brought into the equation and it is governed by rules in the electrical code.
NOT A GOOD IDEA! Bring in an electrician. It would be well worth the expense and you might be able to find a way to work around those specific requirements.
To convert amps to kilowatt-hours (kWh) for a three-phase system, you need to know the voltage. The formula for three-phase power is: Power (kW) = sqrt(3) x Voltage (V) x Current (A) x Power Factor. Once you have the kW, you can convert to kWh by multiplying by the number of hours the equipment operates.
