electric car outlet requires #6, 90 degree column

[Stevenfyeager]

The specs for this customers car says in the manual it requires #6 Cu, 90 degrees with a 60 amp breaker. Romex is only rated for 60 degreesand 55 amps. I would have to run conduit with #4 all the 100 feet through this existing house. I was sure planning on romex. Boy, there goes my estimate. It is Tesla manual, she wants full power. It is very clear in the manual. Help. Do you all have to run #4 ?

Why not SER?

Do you all have to run #4 ?

You could use #2 al SER if cost is a concern, and use a J-box and nipple into the power port with #6 cu THHN.

Not sure but if I remember correct the Tesla charger I recently installed, the terminals will only accommodate to #3. I do know the unit says terminals to only use copper conductors, that was a 60A unit.

You are correct, it says Cu only

Thank you, I hadn't thought of that.

The on line manual is showing only 3 wires, so I can use SEU. But I'm surprised, because I thought it would need a neutral as this wall connector is WIFI ready....

No, only 2 hots and ground, no neutral required. SEU would work but would need copper, might still bust your budget just saw the price of one, almost $600.00 for 6awg CU - 150ft.

 

[LarryFine]

Okay, SE and the copper pigtails.

You can run #4 romex or #6 in conduit. Maybe #6 MC cable?

That doesn't necessarily mean the whole circuit has to be built with copper conductors. Just the part that terminates on the equipment itself.

Thanks all, I used #2 SEU AL, and changed to #6 Cu in conduit in a j box in basement. (#3 AL was not available around here)

In Canada you can use NM up to 90*C.
