Piping from 1.5" to 1" NEMA 50 amp outlet

[Greg1707]

I have a job installing a 50 amp RV power outlet for a car charger. The plan is to run the 8-2 UF through the attic and down the side of the house to the RV outlet. The UF cable will be sleeved in a 1" PVC conduit directly into the top of the box.

The power box has pre drilled holes for a 1.5" conduit hub. How do I transition from 1" PVC to the power outlet that is set up for a 1.5" conduit?

Use a threaded reducer in the hub. Also #8 UF cable is only good for 40 amps.

The receptacle in the link needs a 4-wire cable. As Infinity stated #8 UF-B cable will need to be on a 40 amp breaker and charge rate will need to be set at 32 amps.

RV power outlet, not an EV charger.

Or a 1” panel hub? I think those take standard hubs.

So, what should I use to plug in the EV charger??

OP says RV power outlet for a car charger. RV 50 amp power outlet is a 14-50 and has 2 ungrounded conductors, a neutral and an EGC. Seems he needs 3 wire with ground cable, and if only using #8 UF would need protected with 40 amp OCPD.

Ok. OP here. I have a job to install an outlet for a TESLA mobile charger. The charger is rated at 32 amps. I plan to run #8 UF cable. What type of outdoor outlet should I use? The instruction say NEMA 14-50. Is this not correct/

That's fine, since there are no 40 amp receptacles a 50 amp is permitted. The OCPD cannot exceed 40 amps for #8 UF cable.

Just wanted to add.

The hole in the top is to mount a 4-bolt hub. It is not designed to directly accept a conduit connector. You need to purchase the correct size hub to match your raceway if you are going to enter from the top.

You can do that, but for a 14-50 you have to run 8/3 to get the neutral (the EV won't use it but the 14-50 receptacle requires one).

Yes, and the hubs are not univerally compitable. Very frustrating.
