Hi,
Can somebody help me? I have a 480 3phase heater that is not working, when I measure phase to ground I get 277 each leg. When I measure phase to phase I get 480 on L3 to L2 but not L1 to L3, and that is what the 24v control transformer is attached to and there is no voltage on the secondary of that transfomer. The transformer is good.
Thanks Much.
