Wiring a 120240 volt motor for 240 volts is as follows. 240 volt motors will have a stronger start compared to a 120 volt motor. The longer the wire the more significant these losses become. This motor running at 120v will have twice the amount of line drop amps x resistance of the wire volts because it is drawing twice the current and it will experience four times the line loss power in watts because amps2 x resistance of the wire watts. 20 years ago i wired it to 240 volts but i wanted to switch it back to 120 volts. A balanced electrical load which may save on electricity compared to an unbalanced electrical load.
This is a brand new oem ge genteq carrierbryantpayne furnace x13 blower motor module combination. Single phase electric motor wiring tutorial.
