Homeowners are terrible electricians that don’t understand that every termination needs to be done with a torque wrench or torque screwdriver that has been inspected and verified to be accurate within the past year or it doesn’t meet code.
Homeowners do dumb shit like tapping multiple circuits off a single breaker, stripping off too much insulation and leaving live conductors exposed, using a coffee can as a junction box, or using the wrong size wire because they don’t know how to read an ampacity table.
50 to 60 amps at 240 volts is over 10kW, terminations matter a lot more at 10kW than they do at 1.8kW (15A @ 120V)
Please pay an electrician unless you have a copy of the NEC and understand it.
I sell and run commercial electrical work for a living.
The problem with this change is specifically that even people who do understand the NEC won't be able to work on their own homes anymore.
You can even convert a hardwired charger into a cord and plug connected charger with a NEMA 14-50P cord end and some #6/3 SO cord, assuming you have access to the line voltage terminal block inside the charger and the instruction manual allows it.
Similarly, electrical switchgear can come with ground fault protection relays that trip at around 30mA of leakage current, which is enough to protect the equipment but not a person.
Anyways, a 250V 50A 2P GFCI plug-in breaker is only about $120, that’s the cost of two 15A 1P GFCI/AFCI combo breakers.
But it is good enough qualify as protection to personnel if it's hardwired.

These sorts of articles could use a geographical indicator since this is an international website - I know it's not part of the original headline, but rarely is [video]/[pdf]/(2013).
