electrical - Why Do 240V Circuits Not Require Neutral Why Do 240V Circuits Not Require Neutral? It's smart to wire a 240V circuit with a neutral conductor even if you don't need it for the current appliance since it's easier to run the extra wire once in case you need it in the future, but that's not required and electricians often cut these sorts of corners since that third conductor adds aIn a 120/240V single split phase system, the two ungrounded (hot) legs are actually connected to the secondary winding of the distribution transfor..Best answer · 42For the second part: clothes dryers often have 240 V heaters and 120 V motors.
