NEC 625.13 says chargers need to be "permanently connected and fastened in place" if they are over 20 amp, 125 volts. But everybody is running 50 amp receptacles and using a 50 amp plug as the disconnecting means. Does permanently connected mean hard wired? And if not in sight of the circuit breaker or over 50 feet away you then need a disconnecting means like a pull out fuse box. So are all these thousands of installations not Code compliant?
