@Lion Heart Play it safe, begin with a 2 pole common trip 15 Amp
breaker; (the smallest you'll commonly find) you likely have at least one of these already in your panel.
In my part of Ontario, these would be common for split receptacles in kitchens. In the 1970's, we used to have two splits on a kitchen counter, typically one either side of your sink then usually one more split, possibly behind your refrigerator, or where you might locate two micro-wave ovens.
Back to your lift. Assuming you can locate a two-pole common trip
breaker already in your panel, find out what it's currently powering then turn it off, temporarily
disconnect it's present load and temporarily use it to
power your lift.
If all goes well, buy another two-pole 15 Amp common trip
breaker.
If your temporary two-pole 15 trips after five or six runs of your lift, move up to a two pole 20.
You'll almost certainly have a two-pole 30 Amp
breaker for your clothes drier and you'll likely already have a two-pole 40 for your kitchen stove.
Canadian Tire and / or Home Depot will likely
stock breakers to fit your existing panel.
Toodleoo!
