I'm working with a 3-phase source that is 120/208V, 4 wire. I want to connect three 208V single phase loads (all the same wattage rating). By that I mean for example, one load would be connected between phase A and phase B. The next load would be connected between phase B and phase C. The next load would be connected between phase C and phase A. There are no neutral connections.
Next, I want to compute the current to size each of the 2-pole circuit breakers. But now I'm thinking this looks like a delta connected 3-phase load (for example a motor) since there's no neutral connection. So to size the circuit breakers, do I simply divide the power of an individual load by 208V or does the square root of 3 come into play.
Can anyone help me with this.
Thanks in advance. :smile:
