We have a Canavac XLS970 central vac unit ( replacing our original
Beam) with an 8.4 inch dual stage Ametec-Lamb motor rated at 13.4amps.
It is running on about 50 frrt of AWG14 Romex on a 15 amp breaker.
Sporadically, on initial startup, it will pop the breaker (Square D
QO15). Upon further investigation, reading Square D's information, I
found they make a "high magnetic" 15 amp breaker for "high performance
loads" like AC, CwntralVac, and microwave applications with a high
"pull-in" current.

Nobody in Ontario has the darn things in stock - Rona did, but since
being taken over by Lowes, they no longer even have them available.

I could wait 'till next week and have the electrical supply order me
one in - but I wanted to fix it NOW --

Turns out the 240 volt (double polet) 15 amp QO breakers are ALL High
Magnetic - and I had a spare one, and a spare slot in my panel - so
I've replaced the single pole with the double pole - we will see what
happens,

Just thought you guys might be interested in knowing the little
tid-bit about the "high magnetic" breaker fix for intermittent
nuisance tripping

We're thinking of a new central vac - replacing 25 year old Beam -
- it's still working but the power-beater and hose have seen better
days .. replacing them amounts to half the cost of a new system.
" Made in Canada " is nice - is there any other reason you chose
that brand ? I was surprised to see a few Canadian made central
vacs Quebec, Stratford, and another one ..
and the others were made in Mexico.

Well, for starters I won't have anything that does not have a
tangential bypass motor. That pretty well narrows it down to a high
end ametec/Lamb motor.
That narrows the field considerably. Beam used to be the cream of the
crop, but they have yielded to the beancounters over the years and are
not the product they used to be.
Of all the appliances and equipment I buy, the vauum is the only one
where I want one that "really sucks". I checked around all the local
suppliers and the dealer in Guelph had a KILLER deal on the Cana-Vac
970. That thing will pretty wl literallyll pull the flooring off the
sub-floor!!! - so I bought it.

The old beam had a funny high pitch noise to it and I didn't want to
have to replace it on IT'S schedule.

Found a loose "baffle" in it when I took it apart, so I cleaned it up,
fixed it, and sold it on Kijiji for a few hundred.

I can't speak to the CEC but the US NEC would have that on at least a
20a breaker. If this is the only load, you can keep the 14ga wire.
I can give the NEC code cites if you want and you can cross reference
then to the CEC.
Essentially motor loads are not the same as general lighting circuits
where the 14ga = 15a breaker rule comes from.
Under some circumstances you could even go up to a 40a breaker on 14ga
wire on a pure motor load. (that is usually a question on the
inspector test)

It is a dedicated circuit (technically) but I have tacked on the
cable modem for the internet (about50ma maximum load?)

If the high-mag breaker does not solve the problem, a 20 amp breaker
will be the next step.

If you have any additional loads beyond the motor, you need
supplemental protection for those loads if you are exploiting the
motor rules. I suppose you could argue that the class 2 power supply
is already current limited but it is still a violation. That also
implies this is a receptacle and that also invalidates the motor
exception since it is not an "individual (dedicated) circuit
Since this is more than 1440 watts, I bet the instructions say it is
supposed to be on a 20a circuit anyway.
The NEC/CEC gives you a break on a motor but it is not a blanket
exception to the rules.
