attic j-boxes

I keep getting hit by different inspectors to j-box attic requirements, but they never seem to pull the code out of their...books. Can you mount a j-box into the fllor of an attic in a 'face up' position?

What is the reason that they give? Physical damage to the cable?

You say faceup in the floor if there is a floor he may have a point.

If you mean attached to the open joists, as far as I know its allowed. At least I hope it is because I do it all the time. They must be located where they are accessible.

Very common. The biggest problem I usually see with them is overfilling and/or lack of cover.

This sounds like the sort of thing that they learned one day. "NO JUNCTION BOXES SCREWED TO THE FLOOR." But it wasn't the junction box screwed to the floor that was the problem, it was the NM coming into the sides of a face-up j-box that was the real problem. But they got it in their head that it was the j-box that was the problem.

We run into this all the time. If the box is screwed to the floor and the cables come in from the bottom there is no reason to fail it for that. But if the cables come into the side in a way that if somebody accidentally steps on the edge of the box and steps on the wires crushing them against the connector, I could see that being a problem.

attic j-boxes

Thanks for the responses. It isn't a floor, it is open joists (floor of the attic). I don't know why in this area they keep calling it, I have been an electrician in four states and know the code pretty well, but it is hard to prove to an inspector that it isn't in the code and they never offer the code article themselves. :lol::happysad:
