Thanks Hotline,

I have been checking the board from the days of Bennie and SDS's. I don't like to use work time to post and I have dial up at home but this is work related. Yes it is GF, 400 amp. It may have been custom made we had deep pockets back then. Over the years we would have an occasional main trip due to a faulted balast, we would repair it and move on. This last one created paper work for me so it is time lose the GF. I just wanted to see if anyone knew anything about them.
Thanks,

Jeff
