No, I understand the code, what I was stating was that taping is still slipped by with the local inspectors here. And I meant IG not dedicated grnd.
The 4-wire (insulated grnd, bare grnd, white, red, black) bx IS however insisted on for patient care.
In the banks we do around here, the spec always require IG plugs even on a system with no isolated grnd bar in the panel. When asked if the want a true IG system, they say no.
I'll usually intall an IG bar in the panel if doing the service install with a ground to the same beam as the building ground if time and $$ allows.
Westuplace, I'm sorry, we seem to have deverted your thread and I appologize.
Rewired: I'm in Ottawa.
Eddy: I gave up on hockey when they started making it a womens sport (no fighting), too boring and too long watching players constantly going to the box.
