What is the minimum number of branch circuits required to serve receptacle outlets in a detached garage with electric power?

Explanation:
Receptacle outlets in a garage must be supplied by a 20-amp circuit, and that establishes the minimum number of branch circuits needed: one. The Code requires a 20-amp circuit for garage receptacles to handle common tools and chargers, and it must be GFCI-protected. In a detached garage, you feed the structure with its own circuit or feeder, but for the receptacle outlets themselves you only need at least one 20-amp circuit. Additional circuits aren’t required solely for serving those receptacles, though you may add more circuits if you have other loads that justify separate circuits.
