| May 22, 2014 at 19:13 | comment | added | Speedy Petey | As Nick said, I have never seen a post that did not allow access to splices. Simply removing the post head is access enough. Things such as parking lot lights or large ornamental posts will have a hand hole near the base. | |
| May 22, 2014 at 12:22 | comment | added | Nick Williams | 1) Even without an access panel, junctions can still be made in the base of a post. Since the post only needs to be unscrewed to access it, Code considers this accessible. Otherwise, every post in existence would require a junction box and handhole next to it, because you couldn't connect the fixture inside the post. 2) Technically, Code does allow SPLICES inside buried conduit and conduit bodies. They do not have to be accessible, just made in an approved manner. But splices and JUNCTIONS are not the same thing. Junctions cannot be pulled through the conduit like splices. Must be accessible. | |

The other two [bellacor.com/productdetail/…, lightingdirect.com/… may still, even though they don't say that they do. With that said... | |

| May 22, 2014 at 11:38 | comment | added | Tester101 | @SpeedyPetey The OP didn't link to a specific lamp post, so I didn't want to assume there was an access panel built into the post. If there is, then of course you could make your splices directly in the post itself. | |
| May 22, 2014 at 11:17 | comment | added | Speedy Petey | After reading my comment above see amended correct drawings.... Although I really see no reason at all for boxes. The splices inside the post are fine and quite trade typical, in everything from a post in someone's yard to the largest parking lot tower light. In such installations boxes would be superfluous. | |

| May 22, 2014 at 3:47 | comment | added | Nick Williams | This is true, Speedy, and I was aware of this. I'm not exactly sure of Tester101's intentions in the drawing, but I'd bet he knew and meant this as well. | |
| May 21, 2014 at 19:27 | comment | added | Speedy Petey | Splices CANNOT be underground unless they are accessible, such as with a flush garden box. Done as shown in the drawings above would not be complaint. | |
| May 21, 2014 at 18:07 | comment | added | Nick Williams | Thanks for the thorough explanation! The first image is roughly what I had planned, but I'll put the junction above ground in the base of the lamp post instead of below ground. (The lamp post will have a wide, surface-mount base.) It's good to know that the THWN conductors are allowed inside the lamp post. | |
