I suggest you consider the Wall Connector instead, the 14-50 is not as cheap was you might think. A quality outlet will run you about $80, you need a GFIC breaker that adds $100+, and you need to order a 14-50 adpater for the mobile connector, another $45. Add in some sort of cable management system for say $30 and your total is $255. The Wall Connector is $550 + a $10 breaker, which makes the total just $300 more. What do you get for that extra $300
- The ability to charge at 48A (on a 60-amp circuit) instead of 32A
- You get to keep the mobile connector in the car so it is not forgotten when needed
- If you add a 2nd Wall Connector at a later date, power sharing is already built in
- Firmware updates to the connector, power sharing was recently added via a firmware update
And I would definatly replace the wire with copper!
If you stay with your plan to run 40-amps to a 14-50 outlet, be sure to lable the outlet as 40-amps
