Why does the code require 20 amp circuits when in Canada 15 amp circuits are the norm for everything?
I have no idea about Canada, but the stuff here that's gonna get plugged into a bathroom or kitchen will a lot of times draw more than 12 amps, which is 80% of 15 amps.Why does the code require 20 amp circuits when in Canada 15 amp circuits are the norm for everything?

Most anything with a heating element is 1500w, or 12.5 amps

Heck, sometimes 20 amps won't trip a 15 amp breaker. That's not the issue anyway, imo. The question was why 20 amp circuits, and it's because 80% of 15 amps is 12. And someone has decided 80% is enough. And 12.5 is more than 12.80% only applies to a continuous load. 15 amps will not trip a 15 amp breaker, ever.

And as @infinity mentioned, it's upward from there
And I know it's for continous load. And I know stuff cycles on and off. But the answer is still there.
20 amps is also a good idea in a kitchen when you have a microwave, toaster, rice cooker, air fryer, hot skillet, and a bunch of other crap on 2 circuits.A 20 amp circuit for a bathroom makes sense, you could be powering a hair dryer, lights, exhaust fan, curling iron, makeup mirror, radio and what ever else your significant other or kids have plugged in.

They don't blow dry?So how does Canada not encounter tripping?
Maybe they do, and nobody has told us about itSo how does Canada not encounter tripping?

I think it is just another case of the code writers venturing into design where they do not belong.

Probably an insider secret that they don't tell Americans about.Don't see the Canadian sparkies making many complaints.

Yeah, they only install Federal Pacific panels.Probably an insider secret that they don't tell Americans about.
