Not coiled white wire, when that one is connected everything is ok, but when I run additional white wire to the bus where coiled wite is connected then it trips.
What other white wire are you running to the bus???? Have you looked at the wiring diagram that came with the breaker? Of the wires associated with the breaker, only the coiled white wire should run the the neutral bus.when I run additional white wire to the bus where coiled wite is connected then it trips.
To be honest, actually I did not, embarrassing. I assumed that since there are 3 ports, that I needed to run additional white wire in addition to coiled one, since there is port in the middle with white dot, so I assumed that I needed to run white from there to white bus. On a side note, aren't these readings high, 282V?
