I'm in charge of distribution of this condo project. We have a 600/347V main
service.
I just installed a 600v - 208/120v transformer and everything is groovy.
The star point (X0) on the secondary side is grounded with uninsulated
copper wire which by code it should be.
I just measured the ground wire and it is carrying 10 amps.
I know that this must be the unbalanced neutral current, but is this ok for
a ground wire to carry that much current uninsulated?
Is this normal? I didn't think that ground wires are supposed to carry
current normally (only under fault conditions).
