Had a question about wiring a dustcollector for my shop.
I have run a 12/2 wire to this and the motor on the dust collector is a
115/230. Can i use a double 20 amp breaking for a 220 amp circuit ?
the motor is set on the 220 phase side. Any help would be great.

Yes as long as the 20 amp double pole breaker and wire is sufficient for the dust collector load requirements. Do not mistake double pole breakers for the single pole tandem type.

The breaker that I have is a ge 20 amp with bar connecting the two breakers together. I did this a while back on my well pump and used the black and white as power leads and the copper as ground.
Is there any other ideas that would work better. Thanks for your help

Stubbie, you have me mystified! For my edification, (smile) would you explain what a tandem breaker is? This is new to me!

Tandem breakers are two single pole breakers that fit into on bus slot. The 2P20 will be fine for the dust collector. Be sure it is wired for 220V, open and verify. Also be sure to run a grounding wire through all the supply hoses to prevent static buildup. The charge can cause a fire in your shop.

Sorry if I wasn't clear I thought by saying single pole tandem type it would be non-confusing. I see the other guys have clarified.

Aww! A light goes on! This is what I thought was a split breaker! I'm thinking that a bicycle built for two is called a tandem bicycle and I'm thinking of one pole going through two breaker elements! Duhhh!

It happens all the time depending on where your from they might be called split, tandem ,twin, duplex. I wouldn't beat myself up too much over it.
