I have a three phase service. Only three phase are the a/c unit. I have a blown fuse in the mAin disconnect that feeds 2 single phase panels and 6 a/c disonects. I have not been able to set up a time to kill the power to change the fuse. The phasing to the A/C disconnect is not kept straight and all wires are red. Here are my voltages at the a/c unit. Can you tell which phase is bad.
A-B 240v
B-C 240 volts
A-C. O volts.
All phases 120 volts to ground.
I am thinking the A phase is the bad one?
Thanks
