I will argue that you cannot use #6 romex for a 48 amp continuous load since you are locked into the 60 degree column and 6 in 60 is 55amps. 10kw electric heat kits are actually rated at 9.7kw because the manufactures know that 6-2 romex is running to most residential air handlers this is done so you can use 6-2 romex . If you were to venture into the 75c column using 6-2 MC or running conduit with THWN then the panel/ breaker terminals have to be rated for 75c.
@@NextGenEvsMaster electrician here. You cannot use the next size up rule because the wire is still inadequate for the load. This is an extremely common misinterpretation - go back and check the code again.
Nice to see someone that knows code. This shouldn’t even be an argument. A 48A nameplate EVSE is considered as a 60A load, and a 55A rated wire cannot support a 60A load. The next size up rule is irrelevant because the wire still needs to support the load.
@@charliespruyt5815 The NEC defines an EVSE as… “The conductors, including the ungrounded, grounded, and equipment grounding conductors, and the electric vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatus installed specifically for the purpose of transferring energy between the premises wiring and the electric vehicle.” Note that this doesn’t include anything actually in the vehicle. Yes the actual “charger” is in the vehicle, but the EVSE is the wall-mounted device, or the cord assembly.

You can use the next size up rule. Then you can use #6 Romex. Not everyone is comfortable with this but it’s correct

Love your stuff dude. Got a power wall 3 and a span panel in the garage!
Would love some more information regarding outdoor 14-50 plugs. Is a GFCI breaker a must?
Love the EV content
When is a disconnect required?
The apprentices are ready to work!
why do you have gloves on sir?
Continuous load is 3 hours or more at max load. These chargers have load management so they do not use maximum for that long. Could you argue that?
Article 625 says all EVSE are considered as continuous loads no matter what.
@@EthanMatlackthank you

I was coming from an ev engineer perspective. Then i checked the nec. I appreciate it
So cool that you owe a Tesla!
