So since the overcurrent device is set to 50 amperes, you'll have to have appropriately sized conductors.Ī safer option would be to build a smaller overcurrent device in to the adapter, to protect the cord and A/C unit. If the A/C overloads, you don't want the cord bursting into flames. This is not typically the way it's done, but this is not a typical solution. Since you're plugging it into a 50 ampere circuit, you'll have to size the conductors to be able to carry 50 amperes. If you're dead set on making and extension/adapter, you'll want to use proper sized conductors and protect the cable from physical damage. DO NOT make, use, or even think about a device like this. This is a theoretical device, that should never exist. WARNING: Using an extension/adapter cord like this is dangerous, and can lead to loss of property and/or life. Extension cords are for temporary use only, and should not be used in place of permanent wiring. If they can't, the solution is to run a new circuit.Īs for making an extension cord, that's not the best option. If they can, the solution is to extend the circuit using approved methods and materials. Since you haven't posted the make, model, or nameplates of the equipment, it's impossible to say for sure if these two devices can be on the same circuit. To do this properly, You'll likely have to run a new circuit. The manufacturer of the AC apparently thinks so or they would not have made it with only 3 conductors. Just not sure if omitting the ground will work.
240 VOLT PLUG COINVERTER HOW TO
I've spent enough time around electricians to know how to connect wires and such safely. So my extension cord would only be 3 conductor (no ground) going into the 4 conductor wall receptacle. The AC side would be a 3 conductor receptacle that fits the end of the AC power cord. The wall side would be an 4 conductor plug that fits the receptacle. I want to make a short extension cord, about 6 ft, to connect the 3 conductor plug from the AC to the 4 conductor 240v wall receptacle. I looked up the configuration and determined that it's a 240v 15 amp set up. The air conditioner arrived today and has only 3 conductors on the power cord. I want to use this circuit to run a 240 window air conditioner when the phase converter is off.
It's there to run a phase converter that I use about 2 hours a week. Maybe someday we'll have something comparable.I have an existing 240 outlet wired into the wall of my shop. The only bad thing is that Ford isn't selling mobile charger connectors for other NEMA receptacles like 14-30 and so on.Įuropean Mach-E owners are able to buy a variety of connectors for their various standards/limits. If a 14-50 connector is plugged into the Ford mobile charger, then per the NEC limitations on the use of that type of plug and receptacle, and limitations of the EVSE itself, the EVSE informs the car that it may draw up to 30-32 amps of current. In the case of the Grizzl-E, it's the installer's responsibility to program in the correct answer via dip switches.įord's mobile charger assumes that national electric codes designed for fire safety were followed. One of the reasons we use EVSEs like the Ford Mobile charger or a Grizzl-E is to answer that question. There is *no way* for any vehicle to communicate with a household circuit and answer the question "how much current can you safely carry?" For the majority of vehicle operators, setting current limitations from the vehicle is the more dangerous approach.
