Maybe. Seems kind of strange tho. My GFI doesn´t have
any *real* electronics inside. And as you say they were on
the other end of the building in your case, I doubt it is RF
interference. Was it a GFI or was it a GFI and a c.b. in a
single housing (although I can´t see a real difference here
either)? What characteristic was the c.b.? (esp. if it is a
GFI and c.b. in a single housing). I use a "K" type, which
is designed for heavy inductive loads. I need this for my
3 phase machine shop. The lathe and compressor will trip
a "normal" c.b. almost every time. The normal "B" or "C"
characteristic will usually flip out, when connected to a
heavy inductive load.
