For those of you with basement shop. Has anyone mounted receptacle on
I have a new house in cold climate and I have that weather wrap on the
wall. I do intend to take it down in the Fall yet I want to run
electrical for my shop.
I am confused about the NEC in this case. It refers to box sizes
needed for 120 and 240 v circuits and stud mounting yet it seems
unclear to me if I am permitted to mount outlets overhead. The
ceiling is 8 ft from floor to bottom of joist.
You can put *EXTRA* receptacles anywhere you want, but
those that are not within a certain distance (4'?) of the floor
don't count in terms of the required spacing for convenience
outlets in an occupiable space. As near as I can tell, the
reasoning for this is that consumer electronics come with a 6'
cord as a standard, and you're supposed to be able to put them
anywhere without needing an extension cord.
I don't know if a basement shop counts as an "occupiable space",
though. Probably depends on how your inspector is feeling that
Run a 2x4 from ceiling joist to floor. Fasten a short section of a 2x4 to
the floor (cement nail or lags) and connect the upright section to the
joist. I installed several of these around my basement at about 6" away
from the wall insulation and mounted outlets at 48" above the floor for
freezer and convenience outlets.
Your local codes may vary so check first. Our codes do allow for overhead
120v outlets but any cords connected to them cannot be used to hang things
from - if you can visualize that.
I'd treat it like a stud in this case.
For a shop, with exposed boxes, I like the 4x4 deep metal boxes, with
the rounded edges, and an appropriate cover. You can get 2 outlets
either regular or gfci, or switch. Plenty of room for wiring, and
expansion. Use stranded wire for easy to wire.
The NEC will want any exposed work in a shop to be in metal conduit, so
this is what you need to do anyway.

It sure is. I would use twist-lock connectors tho.
There should be no objection to mounting a receptacle on a joist (rafter)
for a specific purpose. (ex. The receptacle for a garage door opener in
unfinished garages.) You might consider firmly mounting on a 2X4 dropped
down a foot or so, keeping it above head height but low enough to reach the
outlet without the need to step on something to reach it. Some local codes
require physical protection for wiring below 8 feet.
