Is a switch rated as 120/277 suitable as a DPST shut-off for a 240v circuit?
does the 120/277 mean that it's rated for 'up to 277' volt(s which I assume is three-phase power) and thus safe for 240, or does it need to say '240' on the switch?
just curious - I was looking at these at the store, and was curous!
