More likely it's the noise of a handful of contactors.Could it be heat inside the pullbox?
Please try harder next time. :roll:I'm sorry, I couldn't resist. I tried, really.
It sounds like you worked the contactors until the pole pieces moved a bit and mated closely. It should stay quiet.I then opened and closed the contactors first with the time clock and then manually. 4 or 5 times. The buzzing went away.
Got the call again. Contactors are buzzing loudly again. Any suggestions?
