ECN Forum Forums Code Related Discussion NEC & other Code issues IG and EG in same conduit

Isolated Ground receptacles are not required by code. They are only required by design.
In my opinion, not too helpful.

i would have to agree that only under the most critical system would an IG system prove very beneficial..just imagine how many millions of computers and other electronic equipment is connected to the egc or none at all!

i would venture to say that there is a large percentage of homes in america that are running off a ungrounded system..

the added expense on a large job could add a considerable amount to the total installed price..

go figure..

IBM figured out many years ago that IG was mostly a waste of money and stopped recomending them. Unfortunately a lot of "experts" never got the word and I still hear people talking about how computers should have IG.
If you want IG in your house, just pull a dedicated Romex and use a plastic box ;-)
