Max amps 2021 Kona can handle during Level 2 charging?

[Lars]

Thanks for your reply.


1) So to be sure I understand, it is fine for me to have the 40 amp breaker installed and have 8 gauge wire going to the 6-50 outlet and buy a Level 2 charger rated at 32 amps?

2) Just out of curiosity, when you said that the wires will melt with the 100 amp breaker, did you mean the wires going from the breaker to the outlet or the Level 2 charger wires?

Let's keep this simple;
1. A 40A breaker must wired with 8AWG wire to the 6-50 outlet to give you up to 32Amp. This is a common configuration for an electric stove in your home. (80% load is the rule.) 32Amps will be more than plenty for your Kona.

2. YES! Imagine a house on fire! The wire size is governed by the breaker. It must be matched from breaker to outlet.

Based on your note, please call an electrician.

That is exactly what I'm using, except with a 14-50 socket. Using a 32A Morec EVSE from Amazon, delivers about 7.4kw to the Kona, and the 8 gauge cable from 240V 40A house panel breaker to the socket, gets only slightly warm during continuous use. This is at the "maximum" charging setting in the car.
Works fine

Only reason I didn't specify wire size/insulation temperature rating, is the distance was not quoted, didn't want to confuse the issue with voltage drop or termination temperature rating.
You are correct with #8 @90 degree rating for short to medium length runs, as soon as the distance is increased depending on the load (in this case - 32A), the size may have to be increased to maintain less than 3% losses. There are of course voltage drop calculators for that. This is one I use frequently and have verified the results using manual calculation methods:
