The NEC does not have a 'neat and workmanlike manner' clause, as it is beyond its mandate. If the work spec or local ordinance does not call for I have difficulty how the AHJ could refuse to sign on that basis alone.I recently ran across an installation of a splice box in a nema 3r enclosure.
The uploaded photo shows the installation (a 12" extension was added the box in the photo). Does anybody see any code violations?
What is 110.12 Mechanical execution of work. Electrical equipment shall be installed in a neat and workmanlike manner.The NEC does not have a 'neat and workmanlike manner' clause, as it is beyond its mandate. If the work spec or local ordinance does not call for I have difficulty how the AHJ could refuse to sign on that basis alone.
Exactly, a bad looking job will usually come under more scrutiny by the inspector and if there are actually safety issues they can almost always be addressed with an enforceable code section.I have found there is a definite correlation between neatness(pride in the job) and serious code violations.
There are no box fill requirements for these size conductors and inspector cannot just decide to make some up on the spot.In the case of the picture an inspector could say there is not enough space in the box for the conductors, even though it may not exceed the box fill
How do you apply 316.16 to conductors larger than #6? While the rule says that it applies, there is no volume allowance in the NEC for box fill for conductors larger than #6.Then I was misinformed, I was told on an occasion by an inspector that even if your box is of sufficent volume if you leave so much free conductor that it does not leave enough free space for the conductors its a violation. And when I read 314.16 I can see how that is interpreted like that.
So was I mis informed? If so please explain
Actually you size the box to fit the raceways. The size of the conductors, larger than #6, do not enter into the sizing of the box.It that case you would use 314.28 and use the one that applies (straight,angle pulls). After the reply by iwire to one of my replys it got me to doing more searching and I see where I was in error as you stated there is not a box fill but there is way we have to size the box. So in that instance, you size the box (I am really learning that you have to really word things with very little ambiguity :grin to fit the conductors per the calculation.
I am not sure what section the inspector could cite for that. Without evidence of damage to the conductors, I am not sure that there would be a violaiton.Then I pull in the conductors and say "man I figured way to much conductor my boss is going to skin me if I take back all that waste" so I leave it looong. When its all said and done the inspector comes along and see's that and flags it due to the fact that there is not enough free space for the conductors, even though by the code the box is the correct size. Is that legit?
Sorry if I hijacked the post.
