Hello:

This relates to a question I posted a little while ago.
Answers got me thinking a bit more on this, which i guess I should have
beforehand.
I'll copy my original question below, for reference.

I was thinking of putting up an outside house flood light I mentioned by
using the standard 1/2 PVC pipe to run
the wires inside from where they come thru the house siding to a few feet
above, where I want to put the flood light.
Turns, etc. would be by using the Bell junction type plastic outside
boxes.

Bought a bunch of those fitting you use with PVC, and are attached "by
welding" together with a solvent.

Now I'm wondering if I bought the right things:

Are these solvent fastened fittings Code compliant for outside wiring
where the PVC tubing and fittings would be hugging the outside house wall
?

Or, must I use these liquid tight metal connectors ?
**(I don't know if they come in plastic also; do they ?)

Is the Code specific on this ?

Thanks,
B.

Hello:

Regarding those Bell electrical outdoor junction boxes:

Want to put up an outdoor light on the outside of the house.

NM wire would be coming thru house siding into one of these junction
boxes.

The part of the box that will be laying against the siding has a threaded
hole
for the wire (or some other fitting) to go thru.

It's a pretty rough thread.

Questions:

a. Is it Code required that the NM wire from the house side be clamped
where it enters this type of box ?

b. If so, should I use one of those NM wire fittings that one uses with
the
regular indoor metal junction boxes that clamps the wire, as well as
providing a threaded section on the other end ?

c. Or, just lead the NM into the box and live with it brushing against
the
internal threaded hole of the box ?
(do they make a bushing for this purpose; couldn't find anything
appropriate at HD ?)

d. Or,... ?



NM (non metallic) conduit is allowed by code and as long as you bought UL
rated electrical PVC conduit you are fine (grey pipe in electrical
department). Its actually easier to use this because you have less
requirements for bonding and grounding the condiit and J boxes. I assume
you used compatible NM gray PVC boxes and not tried to interface to a metal
one.
