Lighting was changed out in a gym to T8 high bay fixtures, the old lighting was MH 480 volts.
The gentlemen who did the work kept the old 2 pole breakers and just used one side.
I thought you couldn't do that? You should change the breakers out to a single pole breaker and also run the proper color conductor for the grounded conductor?
is there a code article that states that you must use a single pole cb for this application.
