What is the minimum number of 15-amp branch circuits required for a dwelling unit?

In a dwelling unit, the National Electrical Code specifies requirements for branch circuits to ensure safety and adequate power distribution. According to NEC Article 210, a minimum of two 15-amp branch circuits is required for small appliance loads in dwelling units. This is important because it ensures that there is an adequate number of circuits to handle the electrical loads of kitchen appliances and other areas without overloading any single circuit.

Having at least two circuits helps to distribute the electrical load more evenly and prevents potential tripping of breakers or overheating of wiring, which could create hazards. This requirement is a key component in designing safe and effective electrical systems in residential settings, reflecting the NEC's focus on safety and reliability in electrical installations. Thus, the answer identifying two 15-amp branch circuits as the minimum requirement aligns with these safety standards outlined in the code.
