Plumbers cut the ground off


Recommended Posts

Who hasn't seen this? I had two last week, widely separated towns so two dum-ass plumbers. They see the grounding strap on the water line, 1950's basement. They cut the pipe, hook up the new plastic and leave.

I check the panels for an added grounding conductor, nope, just the one.

Is there no CE for plumbers? Are they all this stupid?

So John, I was under the impression that, in Canada, the service entrance side of a panel was supposed to be isolated from the distribution side. Do I have that wrong?

No, you are right. These old panels have separation when the deadfront is installed. The section over the service side has a 90 degree bend in it that forms a wall in the panel. Then the other half of the deadfront covers the circuit breaker section.

Like this Federal panel, for example. Branch circuits are not allowed in the service section.

You can see the slot cut in the flange on the sides of the box to accommodate the deadfront divider.

I can see that in the picture of the second panel that he posted, but in the picture of the first panel, it looks like it would be kind of sketchy to get such a cover in place without touching the bus tab under the backfed main.

Yes some designs are scarier than others. But I think that Westinghouse panel has a plastic divider. One Federal panel has the divider on an angle between two slits, so the cover flips the main breaker off when you try to pull the cover. I've had some funny things happen when I've turned power off to the whole house that way. One inspector I know has done some arc welding with that same panel design. Most of them have clearance and/or some kind of bus bar protection there. The new panels have a second cover under the main one-piece cover.
