Why Does 240 Volt Not Need A Neutral at Oscar Marshall blog

Why Does 240 Volt Not Need A Neutral. For safety reasons the ground (earth) wire. It's called neutral because it's the conductor nearest ground voltage. It's arbitrarily chosen which conductor to bond to ground. You would not need a neutral for a straight 240 volt welder. So the current is always in balance, thus no. For 240 volt loads, the current flows from one of the 120 volt lines to the other 120 volt line. There is no current through the neutral for such loads. Explaining the physics of why 240 volt ac electrical circuits do not need a neutral. Some 240 volt appliances need this neutral to split off 120 volts from a 240 volt supply, normally to feed a power supply that then breaks the voltage.
