Tesla also specifies 6 AWG and 50 amp breaker for their Mobile Connector.
I wouldn't want to explain to an insurance company why my EVSE wasn't installed to code if there was ever a problem. The whole idea for the 80% max pull on the 50 amp circuit is to provide a buffer and reduce heat. If you go with 8 gauge, you are reducing the buffer and will have hotter wires. |
Again you don't get it. You are not running 50a circuit but 40 or 32 or whatever your charge is able to push.
Edit. although since its a to z to be able to withheld surge you may need a thicker cable to run 40a.
