[Boatanchors] GFI

[Jerry K]

Assuming the BA's are transformer-powered, most of these problems can be
traced to leaky AC line to ground capacitors at the main power input of the
boatanchor equipment. Doesn't take much leakage to trip a GFI. Assuming the
equipment has them (many do), I'd first disconnect both of them and see if
that cures the problem, and if so, replace them with AC-rated line caps from
Mouser. The R-390A list has discussed this problem several times, you might
go to their archives and get more info.

I have had some problems with a Cutler-Hammer breaker/GFI combination unit.
One fed a garage circuit and would trip whenever I used any brush-type motor
on the circuit (power saw, router, et.).  Eventually I replaced it with a
straight breaker and installed a GFI receptacle in the garage.  That worked
Fine with no nuisance tripping.

It's also a lot cheaper to install a separate breaker and GFI receptacle.
