Re: [EVDL] j1772 necessity revisited, "Conspiracy against new EVs?

NEC are actually only "recommended" Guidlines much as the J1772. Many
municipalities are allowed to and will deviate from those codes if they are
stupid.

For home charging in your garage there 'should' be no problem plugging into
a GFCI NEMA 14-50 installed in your garage.
