I have a 14-30 outlet installed in my garage. I plugged my UMC in and forgot to Dial the charging draw down on the vehicle. It charged just fine at 40amps. Even charged at full speed of 28mph.
It got me wondering why the heck didn't it pop the 30amp circuit breaker that outlet is wired to. The UMC draws 40amps. I can view my household electrical use in real time via my "smart meter" and confirmed the charging did in fact draw the full 40Amps. Hmmmmm.
Everything I have read on this forum indicated that the breaker should pop if I don't dial down the charging amperage to about 24amps.
I think I have found the answer and I would like to vet it to the tesla community knowledge base.
The answer, I believe, lies in the fact that a 10-30 outlet is rated at 30amps PER POLE. Each wire and each breaker and each contact is rated for 30amps. Making it a 60amp outlet.
Can someone try and punch holes in this? I have done a lot of research and I am also an aircraft electrician by trade so I do have a firm grasp of electrical theory. It's just that my conclusion runs counter to every other thread I've found on this Forum.
