Conduit along driveway wall/curb

[afazz]

I’m filling out the permit application to add a hard-wired Level 2 EV charger and need to decide whether a trench is necessary.

Relevant info: 2017 NEC code cycle, Pennsylvania USA, 40 amp branch circuit on 240v split phase residential power, fed from a sub panel in the garage. I will add an AC disconnect even though it’s not required per 625.23.

I can’t find any code prohibiting the use of schedule 80 PVC (not sch40 because of physical damage) mounted along the back side of a curb / wall at the back of a driveway, as shown in my cartoon below. I could bury RMC at 6” per table 300.5 if I must, but that feels unnecessary.

Can anyone think of a violation this would cause?

i can't think about why that wouldn't be ok. i think i'd use an expansion joint on the horizontal run

that handrail top tube looks just like conduit though...

Handrail. Heheh. Gonna need some fancy fittings.

Eh, bushings are plenty

Would a handrail pass as conduit?

I would not expect it to at all. It's not listed for the purpose.

Yeah, not sure what I was thinking asking that question besides not much.

What, you ain't no heard of a handrail LB?

Now we are talking and it should be okay when you use rigid conduit to build the handrail right?

Now we're cookin

Rigid Conduit handrail? going to be interesting to see how the conductors enter the conduit and then pass through to the connection box for the charger.

 

[Zeke]

It's a joke.

If you use UF cable could it be used just as protection from physical damage ?

So I decided against the handrail conduit but the rest of my idea worked!

(note: there is an expansion joint on the horizontal run, it's hidden by the tree)
