GE came out Monday morning and checked out what I had going on. They decided that nothing is wrong with the building electrical system or with my control wiring. They installed a new contactor. I turned power back on to the lighting panel and it instantly smoked.
They now admit that it is a known problem with this contactor. Their solution is to keep sending me new contactors until we get one that works.
I am trying to talk them into a deal on a new set-up so we can eleminate this problem.
