Wiring transition to outdoors


Does any outdoor receptacle need GFCI? That's maybe where I got that idea since the lamp post does have a receptacle on it.

yes, outdoor receptacles need gfci protection. the 'advantage' of placing the gfci protection inside the house is you don't need a gfci breaker out at the lamp and you can get by with shallower burial depths, as the entire exterior portion of the circuit is protected rather than just whatever gets plugged into the exterior recep.

Sounds good. Yes that old fixture box with the junction had a closet built around it for a basement bedroom, and all of that stuff is coming out and it will be its own dedicated circuit.

I assume there is no "protective fitting" necessary where the UF comes out of the buried conduit? How about on the inside after coming in through the LB and conduit, any special fitting or retention method there like a clamp on the end of metallic conduit?

Or do I bring a length of PVC to a metal box with that male threaded fitting like I planned? I didn't know if there was anything wrong with that since the inside of the PVC is considered "damp location".

put a pvc end bell on the conduit underground. if you can, fasten the exterior conduit to your rim joist using a pvc conduit clamp and some screws. on the inside, use another end bell. depending on the thickness of your siding, rim joist, etc., you may need a short piece of conduit to get the raceway far enough 'out' from the rim joist to attach the end bell. if you start running longer lengths of pvc conduit inside, you will need additional clamps, etc. to secure it. best to keep it as short as possible and switch to exposed uf.

no need for metal boxes (unless your jurisdiction requires them).

Great! Thanks so much for all of your help.

I guess there's no great way to work with the vinyl siding as far as waterproofing and such. I mean I'll caulk it the bast I can but I know vinyl is designed to expand and contract and move around. Oh well.

not a problem. caulking the siding is par for the course on this type of installation. maybe your house already has similar penetrations. check them out or do a google image search.

Well I dug down a bit more with a garden trowel:

I was able to work it free from behind the concrete but still couldn't get it to budge, so I pulled back the siding to get a better look and cut away the aluminum starter strip:

https://www.dropbox.com/s/leyzt9d059...173631_261.jpg

It still wouldn't budge until after I pulled out that nail from the starter strip:

And that is why there is code to prevent this kind of installation!

I wonder if the whole starter strip was energized...

hey, as long as the nail doesn't pierce the conductors within the uf, you're all good!
