his whole ballast issue goes away when you install the disconnect added to the code a couple cycles ago.
I hope that upgrade is part of any ballast swap.
Now if we could just get NEMA to get the manufactures to standardize a plug ;-)
I could foresee a standard receptacle with different wells for the common voltages and the ballast wired appropriately so whatever you plugged in would end up properly tapped.
Single voltage ballasts would only have pins keyed to the right socket holes.
