As long as you don't exceed the calculated conductor fill there should be no problem. :grin:

This is an interesting question.
Reading the definition of enclosed and enclosure makes one wonder based on the way Marc stated his question.
"...with a locked or unlocked door"


This is a question that I would have to really think about.


Thanks Marc for making this such an easy question to answer...I think you need to get more work, so you do not have time to ask this type of question any more. :wink:
 
IMO yes the room can be a 'box' if it meets 314.40.

As far as the door I would say as long as it meets 314.41 why not?

I also do not see any NEC requirement for locked covers.

I have seen some old Johnson building controls that had JB that where small closet sized and had doors.
 
I'm trying to think of a novel solution to help bring into compliance a customer owned Frankenstein substation that is in the basement of their office for their factory that is situated behind. Declaring the whole room a junction box by some means might just save them a pile of dough. The room is just a bit too short for open wiring on insulators, which is substantially how it is now. Open splices and the whole nine. This room needs some other work done, which is going to bring up the issues of everything that is existing, I believe.

what about requesting a variance on the rule for junction boxes citing age and complexity to bring customer to code (supply pics) and label the door...

Because I might not even need something like a that if I can prove that the room qualifies as a junction box. Citing something as "old" or "complex to remediate" would be two of the worst reasons to get a variance for. They should be the top two reasons to bring a situation into compliance.

Well, it was just a thought and I didn't mean to use those words. Could it be classified as a control room?

I would direct the debate toward this end: Strick compliance with section ____________of the NEC would entail practical difficulties or unnecessary hardship, and:
(pick one or more of these)
___would create an excessive and unreasonable burden;
___would not achieve the code's intended objective;
___would inhibit achievement of some other important public policy;
___would be physically or legally impracticable;
___would be unnecessary in light of alternatives which ensure the achievement of the code's intended objective, or in light of alternatives which, without a loss in the level of safety, achieve the code's intended objective more efficiently, effectively or economically;
___would entail a change so slight as to produce a negligible additional benefit consonant with the purposes of the code. :smile:
