OK, OK, I'll use conduit! I normally run 220V coils so this is even worse
than you guys had been talking about. Remember, this is a dust collector
so other than a startle factor it wouldn't hurt much if it did start
unintentionally.

Lots of good ideas, though. Thanks!

As for running control wiring without mechanical protection, there's
always the possibility that insulation could get skinned, and the two
conductors going to the N.O. start button could short out causing a
machine to start unexpectedly. Anything exposed in my shop is run in
EMT.
