Gary: thank you for all your valuable information. I think you’re right about the confusion regarding using a 60 amp main breaker in the garage panel. I’ll forget that idea. In Canada, we need do a main breaker in a stand alone garage panel. I found that out when I ran power to my outside sauna...

Thanks for your input. I will let you know after I talk to the inspector.…probably after Christmas. I may also just put the 60 in, explain why I did it, and see what he says. I know him so he shouldn’t be too hard on me.

Thanks for your input. I don’t really plan on using it as a shop but I want to be prepared for the EV charging outlet and unknown future stuff.

I actually looked into that kind of breaker nippled into a bigger load centre, as you suggested, but those outside, hot tub GFCI tend to be pretty expensive. I may need more than a couple of slots in the garage, especially if I want a 220v outlet in the future.

In Canada, we need a main breaker in a sub panel that’s in a separate building, such as a garage.…not if they are in the same building though. I could be mistaken but I think it’s the same in the States, except for a garage with only 6 or 8 slots in the sub load centre. I did some research and...

Because of the wire size, I have to my garage, the biggest sub panel I can feed is 40 amps. here in Ontario I need a main breaker in it. I realize the rule is a little different in the States for small garage panels. Problem is, I can’t find a panel with a 40 amp main breaker…60 amps is the...
