Sch 40 PVC only describes the thickness. Doug's point is to use electrical
PVC not plumbing PVC

I have some questions about installing an exterior outlet.

I have a circuit that has 2 exterior lights and an exterior GFCI
receptacle on it. I want to tap into this circuit and add another
GFCI. I plan to tap into the circuit along a run of romex inside my
basement, go out through the house rim joist & deck ledger and then to
the outlet. I plan to run Schedule 40 PVC

Make sure you use PVC electrical conduit that is approved for exposure to
sunlight. Ordinary PVC water pipe will degrade in a matter of just a
couple of
years, and is *not* Code-approved for electrical use.

straight out along one of
the deck joists to the far end of the deck.

Here are my questions:

1 - Is it OK to attach the GFCI receptacle, in an weather proof box,
to one of the joists that support my deck? The underside of the deck
is about 6 feet off the ground and I want to hide the outlet behind
the front rim joist of the deck.

Sure.



2 - Assuming it OK to mount the box under the deck, would it be better
to mount the box such that the receptacle faces down towards the
ground or out towards the next joist?

Doesn't much matter, as long as you have a weatherproof cover for it.



3 - The junction box inside the house will be just inside the rim
joist and I should be able to connect the PVC directly to the junction
box. Should I run individual conductors from the junction box, through
the PVC, to the GFCI or is there a special type of Romex for this
application?

Either one is OK.

Doug,

Thanks for this reply and the later one about "damp locations". I'll
go with individual conductors.

BTW I don't know where you live, but in the area around Lake Ontario,
the sun shines down on our decks, not up from below. (kidding!) The
PVC will be run along an interior joist, so there is no danger of UV
degredation. Beside, I'm going to use Sched 40 PVC.

Thanks again!
