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. 230 volt wiring requires 10 gauge or larger wire which because of its size is hard to bend. A 115 volt air conditioner is more convenient than a 230 volt model because the 115 volt unit can plug into virtually any wall outlet. The nominal voltages delivered by the power company are about 115 and 230 volts but these numbers are sometimes listed as 110220 or 117234 or 120240.
In that case the cable would include only the two hot wires and the ground. 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. You can move it from room to room without any special wiring. If the circuit is dedicated to an appliance that does not need auxiliary 115 volt power the neutral can be eliminated.
