Hello All,
Sorry I have not posted a reply in a LONG time. Been very busy with a new job. I am curious about the controller. Is is physically located at the well or is it back at the house? Does it have its own control circuit just for the board or is it powered of the well pump feed? How far roughly is the feed from the panel to the well? Post a link to the controller because I am always looking at new products on the market. If by some chance the board was powered off the well pump ckt(again I dont know how it is setup), maybe the conductors are under-sized. When the pump turns on, there is a voltage drop and the board gets damaged? How about current flowing through the grounding electrode conductor the the well casing if there is a bad Nuetral(grounded conductor). Just looking at other possibilities besides line surges. As far as TVSS units, I like Intermatic TVSS units. Keep us posted and I am sure someone else on here has a better idea than what I wrote
