[VAC] Re: an electrical question
Scott,
I don't claim to have the experiences or knowledge that Dr. G has; however,
I do have a bit of experience with GFI.
When I started to redo my 55 year old house service, I wanted GFI protected
outlets that might be consistent with present code. The romex throughout my
home is imbedded in the plaster and is stapled to the cement block! I
didn't understand GFI and trashed a lot of walls before I found out that the
GFI doesn't need the ground connection to work properly. This brings the
circle to your A/S.
Dr. G mentioned that GFI could resolve your shock risk. GFI seems to
interrupt the circuit when there's a difference between the hot and neutral.
It seems irrelevant if the A/S skin makes a good ground or not for each
receptacle if each receptacle is in a GFI circuit. I recommend just
replacing the two prong with three prong receptacles and grounding to the
electrical box. A small plug in tester will tell you if the circuits are
properly connected/grounded, etc. It doesn't seem necessary in this case to
run a new ground line. 15 amp GFI can be purchased for about $8 each. A
single GFI can protect several downstream receptacles. The service manual
indicates that many of the receptacles are sequential.
