I know there have been several forums on neutral calculations however the ones I saw always seem to be for residential applications, or didn't quite answer the question exactly for me.
I have a project where we have to reduce the neutral in order to use the existing conduit. Incoming voltage is 208-3 phase
I was told I need to add up all the loads on phase A,B,&C and divide the largest one by 120V, would this be correct? I wouldn't divide by the incoming to the voltage of 208-3?
Side question:
The smaller conductor would still be protected by the over current protection for the larger wires, what would be protecting this smaller conductor?"
