What's the 2017 NEC minimum branch circuit supply to a detached garage?

Suppose one has a refrigerator , overhead door and of course lighting outlets and receptacles. Now the garage door opener may have to be on a separate circuit from the receptacles since a refrigerator and other outlets are involved. 210.23 (A)(2)

Now you may need 3 circuits so a panel is needed out at the detached garage

Why 3 circuits? Would the NEC require 3 or are you saying this as a practical matter?

Then add the table saw, dust collector & air compressor.

Can you actually fit a car in most garages? Especially when they are detached, they are rarely used for overnight parking.

One for lights and 2 for receptacles if there is a 2 car garage with garage door opener.

:?
What's the number of cars got to do with it? There is no defined-by-the-NEC minimum load required by a car stall. The new 2017 NEC 210.11(C)(4) and Exception only require a single 20 Amp 120 Volt branch circuit for all the receptacle outlets within a dwelling garage. . . there is no comment about one stall versus any additional number of stalls.

Or are you really saying that all dwelling garage door openers are greater than 10 Amp loads?

And remember, I opened this thread inquiring about the NEC minimum required branch circuit supply to a detached dwelling garage.
 
Al look at 210.23(A)(2). If you have 2 car garage there is a good chance the garage door opener's will be more than 50% of the circuit....I metioned 210.23 earlier

But Dennis, "a good chance" is not a NEC defined term, let alone, part of 210.11(C)(4) or 210.23(A)(2).

In the oringinal post I said you may need 3 circuit. The code would require 3 if those motor were more than 50% of the circuit, NO?????. The receptacles nor lights could be on the circuit with the garage door opener in that case and the recep. and lights cannot be on together-- that makes 3... I am not sure what the issue is that you are having
 
Well, Dennis, the garage door opener is optional, right? That's the point. Lighting outlet(s) and receptacle outlet(s), however, are required. The minimum requirement is multiwire branch circuit (because the garage is detached) with two overcurrent protective devices with a common disconnect. . .seems to me.

Absolutely, I agree.. I was just adding that a minor thing like that can change the entire setup. IMO, I would probably install a 60 amp panel and feeder anyway.
