Franklin Electric Subdrive Utility Interference
Anybody install a Subdrive Utility and get interference with other appliances on the same service? Every LED in my customer's house buzzes when the thing kicks on. Grounding is good, unit is configured correctly for the pump, brand new conductors, no voltage dip when the unit kicks on.
FE said to install one of their input/output filters - no change. Then they said to install their input only filter - no change. They were the only house on the load side of the utility transformer but I would suspect one unit could cause this to happen in multiple houses if they were on the same transformer.
