So I'm looking at this device:
Doug Fleenor Design - DMX1REL20A
It's just a switch--it doesn't care what you put into it, it will turn whatever goes in ON or OFF.
A portion of the specs:
I've used it before (though I can't remember for what [I've also rented one with NEMA 5-15 s for control of a hazer]), and it came from the rental house with L6-20 I/O connectors. Correctly, as we were using it on a 208V line. I didn't realize until just now that it was only switching ONE of the two hot legs. Is this, or could this, be a problem?
A related scenario:
When using any auto-ranging 90-250V device, the power switch probably only interrupts the hot wire. So when connected to bi-phase, the "neutral" is ALWAYS 120V potential difference to ground. Cause for concern? Should power switches on ALL auto-ranging devices also switch the neutral, just in case?
