Enhancing existing wiring to detached garage


since writing word for word doesn't do any good. ill sum it up to what it says to me

The disconnecting means to a seperate building's feeder or branch circuit(s) shall have a combined disconnecting means rated at not less than the calculated load or a b c or d. Since in this case the calculated load here is practically nothing and it would fall under D (if you were installing a sub panel). It would be saying the disconnecting means for the feeders must be rated at 60 amps

Follow along in your code book....

If I run a feeder to a seperate structure, 225.31 tells me I need a disconnect, 225.32 tells me where to install that disconnect, 225.36 tells me it has to be rated as Suitable for Service Equipment, Now for the grand finale, we get to 225.39 RATING of Disconnect, guess what that section tells ya, yep you guessed it, what the rating of the disconnect has to be. and thats IT! hope your a good sport!

I know its easy to read what you want it to say, but you have to read some sections like its your first time reading them and really digest what its actually saying.
