Tesla Wall Charger Wire Routing

Hello everyone. I’m going to be installing a Tesla wall charger. My current plan is to run a 60 AMP breaker with 6 AWG THNN wire from my main panel. I’d like to run the wiring in schedule 40/80 PVC. Looking through the NEC I’m able to use schedule 80 and run my wires above ground. If I use schedule 40 they have to be buried. I haven’t been able to find a specific burial depth. I’ve seen both 18”-24”. Does anyone have a reference for this?

Can someone vector check my plan and see if I’m missing something? My city is currently following the 2020 NEC.

The determination of physical damage is undefined and very subjective.

Schedule 40 burial depth is 18" for residential installation and as you know Schedule 80 anything above ground.

#6 Cu THHN with #10 Ground has a 75°C terminal ampacity of 65 amps, so protection with a 60 amp C/B is good...

You are only required to use Sch 80 where the conduit is subject to physical damage.

Bean_Man - What is the total length in feet of your installation from the main panel to the wall charger?
