proper breaker

Hi,
Just double checking before I buy my breaker for my central vac. It is a 240v, 10.7 max amp and a 4hp. I already ran 12 gauge and was going to get a 20 amp breaker. Does this sound OK ?

What do the vacuum specs call for?

The unit is the Nutone CV850. I have not recieved it yet, but I have done all the rough in and am getting ready to install the unit.

From what you have written I would say you wouuld be better putting in a 15 amp breaker. 12 guage wire will handle 20 amps fine, but you wouuld be best to get a little closer to what the unit should use as far as the breaker goes.

The best advice I can give though it that you can always have everything wired to the box, but wait to buy the breaker until the unit arrives. Whether you are buying a box or adding to one, you have to buy the breaker seperatly anyway.

You might want to read the installation guide online at http://www.nutone.com/PDF/InstallGuides/CV850ins.pdf . It says you need a 15 amp circuit and a 6-15R receptacle (that's for 240V and 15amps). I don't know if you are allowed to put a 240 volt, 15amp receptacle on a 20 amp circuit breaker.

Thanks again for all your input. I should have researched further on-line myself. the paperwork I currently have does not show the size breaker. I have downloaded the spec sheet and will pick up the 15 amp breaker as they suggest along with the specified receptacle. These boards are a must for any homeowner.
