I'm ready to start my outside project which consists of a GFCI receptacle, a pair of flood lights and a switch using pvc and weather tight boxes. I paid all kinds of attention to getting the correct conductors (UF, THWN) and equipment but didn't even consider my splices. I was planing on basic wire nuts, "greenies" and some Ideal In-Sure connectors. Am I OK??

Thank you,
Ed

An inspector told me a recent code change was that splicing materials used in wet areas needed to be rated for the environment and regular wire nuts could not be used any longer. I don't know about about the In-sure push-ins.

You can usually do one of a couple things:

1. put in a hand hole or ground box and make the joints in there. You will need to have connectors rated for wet conditions. They make wire nuts filled with silicone goo that work


2. use an underground splice kit. They are designed to be used as direct burial.

Your proposed method will work only if you put the splice in a waterproof box. Even then I tend to use the silicone filled wirenuts. It never remains as dry as you want it to.

None of the splices are under ground, they are all on a wall in different boxes.

If you are using standard wire nuts, it's a good idea to fill each wire nut with a little bit of silicone before twisting them on. Then, tape the wire nut and position them in the box so they are " upright" and won't hold condensation.

what kind of boxes?

Is this in conduit?

The boxes are the kit sold at electrical supply stores. My 2 gang box is made by "Red dot". They are metal, have threaded holes for conduit and knockout plugs and gaskets.

I am using PVC conduit to run THWN out the house and up a pipe to the flood lights.

Then UF will head to the shed for some more lights and receptacles.

The boxes are, but the splices are NOT.

in that situation, what you have will work. For some reason I thought you were splicing underground. I still prefer silicone filled nuts. There is usually enough dampness to cause some corrosion.

I just noticed that the In-Sure push-ins say "For dry locations only." Would inside the box be a "Dry" location?

Thanks again

Yup, that's exactly what I said. :thumbsup:
