hi everyone,

Really excited to be picking up my model 3 next Saturday (blue - VIN 36xx) and am trying make sure im set up for charging. our home is relatively new and the garage was prewired with for an electric car charger. when we purchased the house, I had asked the contractor to place a NEMA 14-50 outlet where the pre-wire was.

My plan for now is that I can use the mobile connector with the NEMA 14-50 outlet for the new car.

I looked at the wiring run and it looks like the cabling that goes from the outlet to the main panel is labeled “Romex AWG 2 CU 3 CDR WITH AWG 8 GROUND TYPE NM-B MAX 600 VOLTS”.

We have 200 amp service. From what I can tell, this wiring should be able to handle 100 AMPS. Is that correct?

If I wanted to install a HPWC, would it just be a matter of switching out the breaker to a higher amperage and the outlet to the HPWC?

Is this worth doing or do many people just use the mobile charger with the outlet?

Thanks for any feedback!!
