Dwelling garage ckts

[smoke stack lightning]

Can anyone tell me where to find where it says in the NEC that a detached residental garage having several ckts requires a sub-panel?

 

[iwire]

225.30 only allows one branch circuit or feeder to a separate building or structure. (There are a few exceptions)
