White (N), Black (L), Green or Cu (Gnd), standard for 120v circuits.
For 240v use, the white wire should be marked red at the ends, and
the Gnd becomes the 240 and 120 N-Gnd.

I guarantee that I can.

The bare wire in romex is insulated for 600v.

In a 4-wire 240v circuit, the ground wire (Grn) as well as the
neutral wire (Wht) carry zero current. Red and Blk carry all of the
current.

Makes sense because it is electrically reasonable. Sometimes the
Code is, and sometimes it isn't. As I see it, not requiring a MOV
across NEC / UL approved switches suggests that whoever wrote the
present Code needs to take a course in Reactance/Susceptance/
Impedance/Admittance.

You would make a good Mormon or a good Catholic -- and I, for damn
sure, would not.
