In 2020, the national code started requiring GFCI protection on 240-volt plug receptacles. This now moves GFCI breakers to hard wire chargers resulting in better chance of nuisance trips.

It's not a big deal. In much of the rest of the world, entire homes are on a master GFCI. Home chargers there still work fine.

I can't imagine GFCI will a problem with chargers. If it's tripping, something is wrong.

The breaker manufacturers are making EV specific GFCIs.

If your charger is already installed it is not required to meet the newer code, you are grandfathered in. Additionally, the 2020 NEC does not apply to every state. Virginia recently adopted it and other states have not. Some states are on 2023.

I do find that that the GFCI breakers are overly sensitive. I am optimistic that manufacturers will improve.

My in-laws were experiencing GFCI breaker tripping almost every day with their ChargePoint EVSE. I hardwired it and replace the GFCI breaker with a standard one and it hasn't had a problem since.

The rest of the world uses RCD (residual current detectors), not GFCIs. The RCD trip threshold is between 5 and 6 times higher than our GFCIs.
