Too much voltage 246v from power company
To anyone with advice,
I've had 2 refrigeration compressors go bad because of too much voltage from panel to condensing unit. Currently 246v. I've solved the problem with a transformer but have this question for all you electricians.
Why does the power company say "they are within their range" at 120v plus/minus 5% which puts each leg at 126v or 252v for 1phase? Compressors are 208/230 and can't handle that kind of constant power.
Any thoughts are appreciated!
