NEMA 14-50 or hardwired?
40A max vs 48A

40A vs 48A. A NEMA 14-50 outlet sits on a 50A breaker, and the 125% rule caps charging at 40A (9.6 kW). Hardwiring on a 60A circuit allows 48A (11.5 kW). For a Model Y Long Range AWD that's about 31 vs 38 miles added per hour.

Pick the outlet if you already have a 14-50 in the garage, you rent, or you might take the charger with you. The Grizzl-E pick below plugs straight in. Overnight, 40A refills a typical day's driving in under an hour.

Hardwire if you're running a new circuit anyway, the car accepts 48A, or the charger is outside. Fewer connections to wear out, and a hardwired unit can be set to whatever your panel can spare.

One gotcha. Newer editions of the electrical code require GFCI protection on 240V garage outlets. Some chargers have their own ground fault detection and can nuisance trip a GFCI breaker. Ask your electrician which way your local code goes before you pick.

Either way the speed gap matters less than people think: at 33 miles a day, both finish long before morning. Breaker sizes for every charger.
