I’m finishing up wiring a sub panel in an outbuilding. There is an underground run of PVC conduit with THWN, which comes up to an LB on the exterior wall. On the inside I used flexible conduit so I could have a tight bend that comes up to the breaker box. Is this code? I can’t find anything in the NEC about this specific instance. I’ve attached a photo for reference.
The outbuilding is an office/man cave for me. I’m going to finish it with drywall. Currently there are 5 total circuits planned, each 120V: lights, a split A/C (20A max), and some 120V outlets. I don’t plan on ever having any heavy equipment out here, so there aren’t any 220s.
The feeder size is 6/6/6/8 (60A max). I’ll have a 60A double-pole breaker in my main panel and a corresponding double-pole 60A in this panel which will act as a main breaker/disconnnect. I know 60A is massive overkill. It’s a 120foot run and I wanted things to be as efficient as possible in terms of voltage drops.
That still leaves me with 1 open slot that I can’t really think of what to do with. I chose a smaller panel because I didn’t want to stare at a huge panel all day, and I just couldn’t think of any additional needs. Even the outlets could have really been consolidated into 2 circuits instead of 3, but I wanted the isolation for the computers/servers.
I hope I didn’t miscalculate. Am I able to use 2 of the slots in this panel for a double-pole “main breaker”, or do I need a box with a special slot for that?
Here’s a photo of the bend and panel label. It’s fairly tight, but I don’t think it’s deforming the tube like it mentions in 350.24. I can measure the radius if that helps.
