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,... ?

In most jurisdictions, you will have to get a permit to install electric =

service and that installation has to be approved and signed off by an=20
electrical inspector.
I am not an electrician, but I will assume that there is a specific code =

for plastic pipe used for electrical conduit for the following reasons.
1. My pool electric is supplied by plastic pipe running from my main=20
breaker box to a sub panel by the pool. The pipe is grey, not white,=20
black, or any other color.
2. I had electric service run to a new sunroom installed on the back of=20
my house. Due to a slab foundation by the sunroom, the electric had to=20
be conduited through the wall of the basement and then underground to=20
the sunroom. Grey plastic pipe again. (Both of these installations have=20
a molded 90=BA elbow with a screwed on door for access into the elbow=20
outside of the foundation wall).
3. I watched a union electrician install a new 200 amp breaker box in a=20
home that only had 100 amp. He said he had to put the main ground wire=20
into plastic pipe running to the rod stuck in the ground outside the=20
foundation. He did not have any pipe with him and was going to run to HD =

to get some when I offered to get some pipe from my garage. He said it=20
had to be grey pipe to meet code. I only had white pipe, so he made the=20
HD run.
All of these incidents happened in NY. Your results may vary. Check with =

your local building department or electrical inspector for confirmation.=

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.

Yes.

I worry when I hear "pipe" and "electrical" in the same sentence.

You should be talking about non-metallic conduit.

You do mean grey PVC "Conduit" and weatherproof outdoor boxes, right ?

Hi,

Absolutely.
