115 vs 230 volt plug. Years ago i used to have an adapter on the generator to run a regular extension cord over to the pump in order to test it with 230 volts. Window units with standard three prong plugs may be used in regular household receptacles regardless of whether the air conditioner requires 110 115 or 120 volt electricity. Depending on the power company to some extent but usual variation is 115 volts 5 which 109 to 121 volts. In that case the cable would include only the two hot wires and the ground.
In some cases a 120 volt window air conditioning unit may have a round three prong plug of the same configuration. You can move it from room to room without any special wiring. Work was done by a real electrician the color of the wires from the breaker to the motor will tell you there will be 3 wires one is green thats the ground if the other 2 are red and black its 230v single phase that equals 2 hot legs and a ground 110v will be either one red or black one white and one green the white is a neutral so you have one hot leg one neutral and. 230 volt wiring requires 10 gauge or larger wire which because of its size is hard to bend.
