Underground Feeds

[Kjc59]

I have to get conduits to lights inside this structure. Sits on a decorative concrete pad and the feeder comes from the basement of the exterior building. I want to route conduit through the pad into the structure but there are tons of openings for water to get in and then I’m concerned about it being a drain right back to the basement. I need to come in with a conduit, splice, wire the light, and then back out to another conduit and on to the next structure. The bottom of the structure is stainless steel also, all sitting on the pad. This screams to me to use direct burial but conduits are required as building standard. I have no clue best way to get conduit and out, keep it sealed, and how to mount in this structure. Any thoughts from anyone?

Yes. Just stub through the slab and transition to a liquid tite w/a drip loop.

Is this your first sorta "left field" architectural accent lighting? If so, it gets far worse!
If you stick to code AND use drip loops it'll be fine- water or not.

I like that. I was tossing around some kind of goose neck

Do you typically put a drain hole in the bottom of the drip loop then?

Or a weather head?

Very good idea. Stub up into it and add weatherhead. You can add a second one as well to send the wire back out to another one of the structures.

Will the artist/owner complain that your electrical stuff is visible? They may want stuff as minimalistic as possible.

At a certain point there is only so much you can do. Sure I guess you can just poke a conduit up and seal the hell out of it but how long will that last before water is filling in? It be a drain right to the basement and I think you have to do something to prevent it. You can keep the weather head as tight as possible to grade to try and help. Maybe tuck off in a corner too
