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
I had to put a high-trip mag breaker on one circuit which was serving my
shop dust collector. Around here it was a matter of going to the nearest
big-box store -- both Lowe's and Home Depot had them available -- and this
is in a decidedly less populated area than Ontario.
