Default Why do some 240 volt devices need a neutral?

As others have said, if a 240 volt device requires a neutral, it uses 120
volts for some part of it. With the exception of older electric ranges
and cooking equipment, any 240 volt device that requires a neutral would
typically be hard wired or furnished with a 4 wire outlet and cord


It's not so much the age of the appliance as it is the age and wiring of
the building that determines whether a 240 volt range or dryer has a 3 or
4 wire cord. The appliances are typically sold without cords for that
reason. It also helps keep the advertised price down. If a 3 wire cord
is needed, the neutral terminal on the appliance is bonded to the frame.


My point is that only ranges and cooking equipment are exceptions
