Dude?
A code was cited! Instead of talking about this specific case you go off talking about adding things (GFCIs) above the code.
How about debating the facts here rather than your opinions? Nothing you said is germane to the OP.
I stated earlier the my reason was that I could not hold the cover with one hand and install a tester with the other hand.
My biggest beef with this is the fact that it was once code compliant and a modification was made. Do I feel bad for the siding guy? Sure.
I'm sorry that he didn't know better. Things happen.
Just like this guy who used corn cobs to 'sandblast' the paint off some motors. This was inside after disassembly.
Step to the plate fix it and move on.
This made me laugh. Somehow, my analogy about GFCIs is irrelevant, but your analogy about sandblasting a motor with corncobs is totally relevant? Okay...
If the siding is installed in such a way that the cover can't be opened or can't be removed, then I totally agree that it's non-compliant. I'll go out on a limb here and assert that we all agree on that.
It seems to me that we have a difference of opinion on what is and is not accessible. Some of us believe that you must be able to get both hands in there to manipulate things, while others believe that it's accessible as long as you can open and remove the cover.
If you take a second look at my earlier post, you'll see that I never said that I thought the installation in the OP was compliant. I don't have enough information to make that call. All I did was take issue with two assertions that had been made earlier in the thread: (1) the idea that the Code has to specifically allow an installation in order for it to be code-compliant; and (2) the idea that the installation MUST be non-compliant because the Inspector objected to it.
Actually, my personal opinion is that this installation is very possibly NOT compliant, but I can't tell for sure without being there in person. My reasoning is this: The wires in that box need to be long enough that the receptacle can be replaced without removing the siding. If the original installation met the code-required 3" past the edge of the box for the conductors, then it
might be possible to replace the receptacle without removing the siding. If, however, the original installation was like a lot I've seen (in older homes), and the wires were too short to begin with, then there's no way you'll be able to replace that receptacle without removing/damaging the building finish. But if that's the case, then the installation wasn't really compliant to begin with.
Here's a question, though: Would it be acceptable to put a 3" extension ring on the front of that box and then use long pigtails to connect the receptacle to the existing wiring that's way in the back of the box? It might be difficult to install the wirenuts, but it could probably be done, and it would almost certainly be a whole lot cheaper and easier than re-doing the siding. Or would that create a new violation, because now the wires entering the box don't protrude 3" from the front of the extension ring? Just throwing out ideas...
