Hi Michael,

I recommend that you rewatch the video in that unit, since this is explained quite clearly there. Look especially at the mark-up of the schematic around 10 minutes in.

See how it shows line coming into the motor through the overload protector, and then neutral coming through timer cam 6? That’s how we know that the timer cams are switching neutral to the motor windings, not line.

Once you’ve rewatched that video, let me know if anything still isn’t clear.
