Residential Post Light

would not pipe snap also??? Never seen any damage from this just wondering.
I live on sand I would fiqure my soil shifts more then most areas

Yes,it could, but not likely. I’ve located and found faults with conductors emerging from concrete. There is a reason for 340.12.

In regards to wiring the light head itself do you technically use those weatherproof wirenuts, or do you use regular wirenuts?
Do you just need the weatherproof ones when the connection is in a junction box below grade? I guess the shorter question would be “When do use weatherproof wirenuts?

 

[ptonsparky]

Never used ‘weatherproof’ in an outdoor fixture. Assuming you mean the gel filled ones.

Yes

When do use weatherproof wirenuts?

In underground locations or hand holes wet location wire connectors are required.

300.50(B) Wet Locations.
The interior of enclosures or raceways installed underground shall be considered to be a wet location. Insulated conductors and cables installed in these enclosures or raceways in underground installations shall be listed for use in wet locations and shall comply with 310.10(C). Any connections or splices in an underground installation shall be approved for wet locations.

314.30(C) Enclosed Wiring.
All enclosed conductors and any splices or terminations, if present, shall be listed as suitable for wet locations.

Thank you

I had an inspector say I needed the wet location wirenuts in a bell box that was mounted about 18” above grade that was being fed with an underground pvc conduit. It was a two gang bell box for a switch and receptacle for a pool pump. I didn’t think he was right, or was he? From what was said above it appears he was incorrect..

If you have a pvc junction box rated for direct burial that is mounted with only the cover exposed would you need to use wet location wirenuts?

NFPA 70 (2023) 100 Definitions
Location, Wet. (Wet Location)
A location that is one or more of the following:

• Unprotected and exposed to weather
• Subject to saturation with water and other liquids
• Underground
• In concrete slabs or masonry in direct contact with the earth

Enhanced content
Both the inside of a raceway in a wet location and a raceway installed underground are considered wet locations. Therefore, any conductors inside the raceway would be required to be suitable for wet locations.

See also 300.6(D) for the general requirement for protection against corrosion and deterioration, which also identifies several examples of wet locations. For requirements for luminaires installed in wet locations, see 410.10(A). See Table 110.28 for a list of suitable enclosures for wet locations.

Based on this I would say yes. Based on what I've seen in practice when not used, I again say yes they should have been. Inside a NEMA 3x and 3R enclosures seen enough moisture that the standard wire-nut was fully corroded inside.

Can I sleeve 14-2 UF in 1/2” pvc without a problem? I thought 1/2” pvc might be easier to get in the pole

Sure.

I was planning on doing this tomorrow although my suppliers don’t carry bell ends this small. Can I direct bury 1/2 pvc male adapter with a plastic bushing instead of a bell end?

Yes.

Hack that I am, I don't replace AFCIs with standard breakers, but I have used the back edge of a razor knife to smooth the cut ends of PVC.

Is that something your not suppose to do- sometimes that pvc sharp

PVC can be sharp. It needs bushed.

Why would a sleeve require a bushing for UF cable? The jacket on UF seems pretty durable to me.

Sounds good to me, But is there a difference in the code related to the PVC conduit used as a sleeve vs as a wiring method related to the open end or termination?

There are some requirements for protection when sleeving NM cable but I don't think they apply to UF installed in the ground.

Asking because don't ever recall seeing a bell end put on the PVC when sleeved for UF or NM. But that doesn't mean a thing around here.

I have to install some residential post lights that have aluminum poles. The hole at the bottom of pole is approximately 1 1/4” , and we were planning on running UF cable. I may need to use concrete at the base as well because the soil is very sandy in this area. What would you use for a bushing where it enters the 1 1/4 access hole, or would you even use one? You can’t obviously get a locknut inside the pole for a fitting. I’m guessing that UF can’t be put in concrete, so that may be an issue as well. What have you done in the past?
