Setting up a new woodworking shop - have some questions

[Rod Sheridan]

The same amps are spread over two conductors...

That's not true Jim, a 20 ampere load at 120 volts is a 10 ampere load at 240 volts.

In one case there is 20 amperes flowing in the circuit, in the other case 10 amperes. Both loads are single phase, so 2 conductors per circuit........Rod.

Good hint Bernie. I've never seen those before.

I wonder if there are any that will automatically turn on my overhead dust filter and then turn it off when the dust subsides.

I stand corrected...I wasn't thinking when I replied.
