The main coils are wired for 220 but the light bulb and other
parts like the timer use one side and the neutral.


Wait, I thought we just got through learning there IS no neutral in a
240 circuit?? I didn't realize that they were out of phase with each
other.


No - the discussion was that for a 220V circuit, no neutral is needed.
However - when looking to also utilized 120V within a device that is hooked
up to a 220v circuit, then a neutral must be provided. The example given
was a clothes dryer. The dryer coils run on 220 and your clothes would dry
just fine with no neutral. However, the timer, any lights that may come on
when you open the door, etc. run on 110V. Therefore, you have to supply a
neutral so that those 110V devices can operate off of one leg of the 220V,
and neutral.
