I'm new here. I would appreciate any helpful info.
I have installed an EV level 2 charger in my garage. It is a 30 AMP charger. I is around 8 feet away from the breaker box. I used 8/2 wire to be on the safe side for future possible upgrades and used a 2 pole 40 AMP breaker for now. The EV charger is working fine. The question I have is that the two hot wires are 8 gauge but the ground wire is a bare 10 gauge wire. Is this OK or should I replace the ground with an 8 gauge wire?
Thank you so much for your kind support.
