Location of Junction box
 
I have a 4" x 4" x 2" square J-Box in my attic where I want to add/change the wiring.
The box is currently located very close to the floor, so it is a bit difficult to access.
I was told a while ago by someone here that a J-box must be a specific distance from the floor or roof. I seem to recall 1m, or 3ft, but that sounds like too far.

I have been searching through the 2005 code, but cannot find this specific info.

Can someone tell me how far from the floor I need to re-install the J-box?

Note: The attic has a full floor. There are bats of fiberglass insulation between the rafters.

Thanks

There is no such requirement.

Thanks. I may still move or completely eliminate the J-box, since I am considering pulling new wire to the two receptacles that this box feeds.
If I do that, I'll just daisy-chain the circuit.

The term "accessible" is possibly a little interpretive, but I agree with InPhase277 that there is definately no such requirement. The box has to be accessible and nothing more. If someone can get at it without any sort of destructive measures, it is good to go.

A related question. When I replaced my over the range hood with a microwave, the feed to the hood came up from the crawl space and I did not have enough slack to move up to the lower cabinet. (I tried to pull the wire back down to the crawl but it was stapled and I could not move it. The wire is in an insulated outside wall.) I installed an old work box behind the MW and ran up to a new receptacle box in the upper cabinet. I soldered and wire nutted the connections and put a note in the new box that there was a JB behind the MW. Does this meet the rquirement of accessability? You have to take down the MW to access the JB.

I think you are OK. Th MW is an appliance and not permanent piece of the dwelling.
