Until the 2023 NEC, each EVSE was required to be on its own branch circuit. If one lives in a jurisdiction that has not yet adopted NEC 2023, this is technically a violation. That said, Iād do it anyway! š
This is not a recommendation. If you smoke it, you own it!!
If you run a 20A, 240V circuit to a regular NEMA 5-20R receptacle outlet, you can plug the Ford EVSE into it using its 120V dongle and charge at approximately 2.8 KW which is double the L1 rate. Just donāt EVER plug anything else into...
Iām fine, thanks. A branch circuit for powering an EVSE is to be sized at 125% of the EVSE max current. It can be used on a 40 or 50A circuit. See NEC article 625.
OK. To select the travel direction on an EV requires only a simple electrical signal. The bulky mechanical contraption on our trucks is overly complex and is prone to failure. Thatās why it sucks and some are replacing it with something much more simple.
What your neighbor is doing is potentially dangerous. Heās setting himself up for a Darwin Award. Use a breaker interlock or transfer switch, and use an inlet, not an outlet for connection.
Thereās a thread on here where this was tested. Best efficiency was at 40-48A. It only dropped very slightly above that. At lower rates, vehicle systems overhead decreased efficiency.
It will vary depending on the vehicle, of course, depending on the systems running during charging.
Make an adapter to power the Ford Mobile Chargerās 120V dongle with 240V. That will charge at 12A, 240V, or about 2.8 KW.
Disclaimer: donāt attempt unless you know what youāre doing. If anything goes south, itās your responsibility.
