Auto sensing for Travel charger/connection

[fhteagle]

he can only do a 30 Amp breaker.

If he installs a NEMA 14-30R receptacle ("outlet"), you can buy a 14-30P (plug) to 14-50R adapter. This would let you plug in the 14-50 end of the EVSE, but does not guarantee the EVSE knows of the correct amp limit for the circuit.

The OpenEVSE can be purchased with a 14-X plug that will fit in 14-30, 14-50, or 14-60 receptacles .

I know for sure the OpenEVSEs can be permanently or temporarily set to any amp limit between 6 (minimum J1772 spec) and the physical limits of the wiring and relay in the OpenEVSE. OpenEVSEs are not cheap, but are absolutely worth every penny, easily repairable, and the firmware is under continuous improvement.

The Ford travel charger is made by Webasto, yes? AFAIK those units take their limits from which plug pigtail is put in them. Does Webasto make/sell a 14-30 plug to Webasto proprietary pigtail?

There's a lot of good information here but it's probably more in depth than it needs to be.

If you want to use the Ford Mobile Charger to charge your truck at 240V/30A you must install a 40A or 50A circuit with a 14-50 outlet.

There are chargers that will charge at lower amperage and the Ford Mobile Charger will work with 120V.

If it were me, I'd install a 50A circuit and charge when the load on the rest of the house is low. This is a perfectly safe approach to the problem. If you exceed 60A on the main breaker, it will trip. It's also the cheapest option outside of 120V charging... which might be a good option too.
