Be certain that the wiring on the circuit you plan to use is up to code, not too old. If you plan to use a 15 amp circuit with the EVSE set to 12 amp charging nothing else can be plugged into any other outlet that is on the same circuit. If you plan to use the EVSE on a 20 amp circuit still take care not to overload the circuit. Tip: change the NEMA 5-15 receptacle you plan to use and install a commercial grade or hospital grade receptacle. Make sure the wires are secured with screw down terminals as push in wire terminals are not sufficient for continuous load at 12 amps (or even 8 amps for that matter.)Thank you. We haven't purchased yet. Don't need factory GPS system as well is Android auto but wanted to make sure we could still use location based charging if we purchase an LT. We plan to use level 1 charging at home overnight and want to change default to 12 amps.
FWIW, if the 20 amp circuit terminates at only one outlet it would be inexpensive for an electrician to convert one of the circuits to be a 240V circuit. The electrician would have to change the breaker at the panel and install a new 240V receptacle at the outlet. The circuit would still be limited to 20 amps due to the wiring gauge but any EV or PHEV will charge twice as fast at 240V than 120V. The Volt only requires a 20 amp circuit for its maximum 240V/16 amps (3.6kW) Level 2 charging.Thanks for the feedback. The house was just built. Has a separate. 20amp circuit in each garage bay so likely nothing else in it overnight
