Hi,
I'll try to keep it brief. In my workshop, I have a problem with managing my table saw and vacuum. If I plug them into the same ckt (120V 30A breaker), they will run, as long as there is no voltage dip or heavy load situations. That means the occasional and always at the worst of time breaker popping open. As a remedy I simply switched the vacuum to another line - when I wired the shop I put two ckts wherever any machinery might be plugged in. That works great, but(t) ... It means the hassle of turning on the vacuum, and then the table saw, and opposite to shut down. A pain unless I want to let the vacwm run nonstop.
Setup: My entire shop is switched. EVERY ckt in the shop is manually turned off/on from switches at the main entrance from the house. They're simple, SPST properly rated switches. That way I am confident that NOTHING in the shop was left running when I leave it. All equipment outlets are dead that way.
Everything is wired to code, and passed inspection easily. Now, before I ruin my rep with the zoning board (small, rural town), I thought I'd ask this here :
Would I be in violation of any NEC by putting both the vacwm AND the power saw switching onto a DPST switch, so that flipping the switch turned them BOTH on and off at the same time? I'd color code the switch with both colors of my receptacles (all ckts are color coded for easy ID/management of current draw). Intuitively I feel it's against code, but ... darned if I can find anything that would forbid it. Can you guys?
If it turns out it is against code, my next logical step would be a DPDT relay b ut they're expensive. So, any othger ideas?
Obviously I don't want to go thru the cost of the inspection again if I can avoid it; but I don't want to do anything that's not to code. Oh, and everything's in thin-wall conduit.
Regards,
