Electrician installed a 14-50 in the garage last year that I have been using to charge our MY via the UMC. With a M3 pickup scheduled for this week I thought a HPWC might be worthwhile so I went to check the wiring to see if it could support a 60A breaker but now I’m concerned it’s 8/3 romex from a 50A breaker. Is there an easy way to tell?
