Steve, we have had similar situation in a store. The store was t12 magnetic ballasts and various lights thru out the store were t5 electronic, undercab lights. These lights were causing other circuits to heat up and trip. We had to use a frequency meter to find them. Apparantly the harmonic goes back down the neutral and causes issues with the other circuits. We have had up 100+ cycles and this causes breaker to burn out and all sort of strange things to happen.
