Hi everyone. I have been having some problem with some 2x4 troffers. Customer called last week a bunch of fixtures are out I changed 6 of the ballasts. a few days later they tell me the breaker keeps tripping so I put my amp meter on it it was pulling 24a so I split the circuits instead of 2 circuits now there are 4 for all the lights. I come this morning I see 2 ballasts are out one is one I just changed. What am i looking for?
