Level 2 EVSE

[g-and-h_electric]

Customer is buying a "LUCID" EV. They are getting a level 2 charger ( 60 Amp max, iirc). I have no other info on the charger as of now The feed from the panel is going to be EMT with THHN/ THWN condutors in it ( Chicago area, has to be "pipe and wire).

I see that #6 is good to 65 Amp, and the table allows the next standard breaker which would be a 70 (if I need to ). Anyone have a reason that on a 75 foot run I would need to use #4? Last charger I did, was only 25 feet from the panel so no real need to consider voltage drop, and we had the spec sheet.

Any thoughts or ideas???

60A is not a “normal” EVSE rating. I’d bet money it’s a 48A EVSE requiring a 60A circuit.

The next up common size would be a 64A, requiring an 80A circuit. (Most are rated at 80% of standard breaker sizes - but I’m sure there are exceptions).

ETA - no, #6 is not sufficient if it’s truly a 60A EVSE. The conductors must be capable of 76A minimum.
