Which is the minimum number of 20-amp branch circuits for laundry receptacles?

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

Answer: (A)

The key idea is that laundry receptacles are powered by 20-amp circuits, and the minimum number of such circuits needed to supply the laundry area is one. A single 20-amp branch circuit can serve all the laundry receptacle outlets in the area, as long as the total load on that circuit does not exceed 20 amps. The dryer usually has its own larger circuit (often 30 amps, 240V or a dedicated 120V/dryer arrangement), so the laundry receptacle circuit is separate from the dryer’s circuit. You’d install additional circuits only if the load or future plans require it, but for the minimum requirement to supply laundry receptacles, one 20-amp circuit is sufficient.
