Junction Boxes Under Blown-in Cellulose


Allowed?
Still considered accessible?
Do I need to 'flag' them?
What will the inspector expect?

Thanks! (once again)

allowed

acceptable

yes, still considered accessible

not desired if you are the electrician trying to find one

flagging is not required but a nice touch, especially if you are the electrician trying to find one.

As long as they have a listed cover, OK.

However:

1) Potentially a problem if connected older wiring listed for 60C rather than 90C, and now running hotter under the insulation.

2) Potentially a problem if no longer visible wiring and it's connection to the box is subject to damage when someone attempts to traverse the attic.

Mike: Nope, all new wiring/12-2 so not a problem. Po)

This particular JB is for the smokers, 4 go into one box and all interconnect.
Back when I first installed them, it was easier this way than chaining them, believe me. However, now, I COULD have chained them.... if I wanted to rewire the whole thing..... I didn't.

just a note: wiring that runs within (I think Marc said it was 3 feet) of the scuttle into the attic must be protected either with conduit, through holes in the joists, or running boards along side the cable so you cannot step on them and damage them.

I know, (but it's 6' I thought...) but my last wires are 7 or 8 feet away from where I plan on making the hole, so I'm good. Also, all of my wire is on runners up there, neatly taped, tied and stapled.
