I've been researching and couldn't find any answers about my specific question. Is NEMA 14-50 limited to 40 amps? Or no? My Tesla is the updated model so I have the 48 AMP charging. Will a NEMA 14-50 be able to charge at 48 amps? Or is it limited to 40 amps? If it is limited to 40 amps will I have to purchase the HPWC to get the full 48 amps? Thanks!
