Apologies in advance for the noob question...
Earlier this summer we had a whole house humidifier installed. A 240v line was run through the garage to the basement to power it. At the time I thought it would be "years" before we got an EV. But now I'm expecting a M3 in a couple of weeks.
I have free charging at work, so I wasn't planning on installing anything at home, but then I remembered I already have 240v running through the garage! See photo.
Problem is, the humidifier uses 11.5 amps and it's on a 40 amp breaker. So that leaves me with 20 amps for an EVSE. So I think I screwed myself by not thinking ahead and telling the electrician to future proof it (put it on a 60 amp breaker for example).
Questions:
1. Is it true that EVSE is supposed to be on its own "line" / breaker anyway? So then none of this matters?
If #1 is *not* true then...
2. I'm assuming I shouldn't have a 14-50 plug installed in this junction box right (again, see photo)? Knowing that 11.5 is used during the winter months, it should probably be a 14-30 plug (e.g. so a future owner of the house doesn't assume they have 40 amps available to them).
And last,
3. If I do install a plug on this line / junction box, my thought is during the summer I can charge at 32 amps... but I have to remember during the winter months (when I turn the humidifier back on) to dial the EVSE back down to 20 amps... How bad is it if I forget one winter? It will simply trip the breaker right?
Thanks for any info!
