How many receptacle outlets does the NEC® allow to be connected on a 120-volt residential lighting or small-appliance branch circuit?

• A. Five
• B. Ten
• C. An unspecified number of
• D. Three

Answer: (C)

The National Electrical Code (NEC®) does not specify a maximum number of receptacle outlets that can be connected on a 120-volt residential lighting or small-appliance branch circuit. This flexibility allows for the installation of as many receptacles as necessary based on the design and usage needs of the space, so long as they do not exceed the branch circuit's overall capacity in terms of current draw. This aligns with the principle of ensuring that the circuit is not overloaded while fulfilling practical requirements in a residential setting. Additionally, any connected devices must be considered to ensure that the total load does not exceed the rating of the circuit. Proper circuit design and load calculations are vital to maintaining safety and functionality. Understanding the NEC's approach to receptacle outlet connections emphasizes the importance of considering both the specific requirements of the installation and the actual usage patterns in residential environments.
