| Taking a leg from a 220v circuit Currently I have a shared neutral circuit 120v in my garage that goes to a dedicated receptacle for a dust collector. Then the other leg goes to the garage heater (gas). At some point if I upgrade my dust collector and it requires 220v can I switch the circuit to 220v 20amp and then take one leg off and still have the heater hooked through this way. It is 12/3 wire. |

Yes. On a code technicality (exception), you could. The MWBC would need to be fed from a 2 pole common trip breaker.
It would be a very hoakey arrangement, IMPO.
It would be much better to install a dedicated circuit for one or the other. Most likely you'll overload the circuit if you attempt to run both at the same time.

Question: What sort of residential dust collection (Im assuming it's another word for central vacuum) requires 220v?
It must be a monster! |

| I think he is talking about a true dust collector like they use in wood working shops to suck the dust up from saws. |

240V dammit! |

| Sorry 240v. Yes this would be a dust collector for woodworking.
Something like...

| I had the earlier version of the same collector. Do yourself a favor and just get a Jet or a Delta. You'll save some money and headache. The Grizzly was noisy as f___ and leaked like a sieve.

kudos:9 | +1 on the Delta, they have always made good tools and their collectors are no exception. I assume you have ducting in place already? |
