Hi all,

I have a house that was built in 1955. The elctrical outlets are of
the two prong variety. I want to run a ground wire from the 100 amp
service to all the outlets in the kitchen and bathrooms and then add
GFCI outlets in these locations. I also want to run a ground wire to
the outlets in one bedroom that I will be using as an office and as
such it will have a fax, printer, and computer that all require
grounded outlets. My question is, how difficult is it to snake the
wires to the outlets? What if I just tape some three wire romex to the
old wire at the outlet and pull it through the existing hole?
Thoughts, opinions?



It's often not that bad to snake a single green #12 or #14 wire thru the
walls to ground the outlets. The ground wire does not have to run with
the current-carrying wires when retrofitting old work. Connect the
green wires to the big bare copper Grounding Electrode Conductor that
comes out of your panel; using a big split bolt connector makes it easy.
I think you can daisy-chain these supplemental Equipment Grounding
Conductors, but I've been using a home-run for each one that I add to my
house.

It *was* too difficult to run a proper ground wire to the outlet by my
kitchen sink, so I just put in a GFCI outlet and a "No Equipment Ground"
sticker on the cover.
