I understand table 250-.122 may be confusing to read but it says Rating or Setting of Automatic Overcurrent Device in Circuit Ahead of Equipment, Conduit, etc., Not Exceeding (Amperes)
20 12ga copper 60 10ga copper
I read that to say if you exceed 20a and do not exceed 60a you are in a #10. Just as a sanity check, what size is the ground in a 10ga or 8 ga cable ... 10ga
OK yes that makes sense. They made it a bit confusing when they took out the 30 and 40 amp columns just because we were so used to seeing those numbers included but when you think about it they weren't necessary when the higher amperage columns jump from conductor size to conductor size with no repetition. So the instructions for the EV charger are incorrect.
