To supply receptacle outlets in a detached garage, what is the minimum number of branch circuits required?

• A. Two
• B. One
• C. Three
• D. Four

Answer: (B)

The main point is that garages require a 20-amp branch circuit dedicated to receptacle outlets, and that a single 20-amp circuit can feed multiple receptacles. Because of this, the minimum number of branch circuits needed to supply receptacle outlets in a detached garage is one. You can install more circuits if you want extra capacity or to separate loads, but one 20-amp circuit meets the requirement for garage receptacles. Also note that garage receptacles must be GFCI protected.
