Which of the following is NOT a type of branch circuit covered under NEC guidelines?

• A. General purpose circuit
• B. Dedicated circuit
• C. Branch circuit for refrigeration
• D. Nominal circuit

Answer: (D)

The term 'nominal circuit' is not recognized as a specific type of branch circuit in the National Electrical Code (NEC). In the context of electrical systems, branch circuits are defined and categorized based on their usage and load requirements. General purpose circuits are designed to provide power to various outlets and can supply multiple loads. Dedicated circuits are used for a specific appliance or equipment, ensuring it has a reliable power source without sharing the load with other devices. Additionally, branch circuits for refrigeration specifically cater to refrigeration equipment, taking into account its unique power requirements. Unlike these clearly defined categories, 'nominal circuit' lacks a standardized definition within NEC guidelines, making it an invalid choice in this context. By understanding the specific definitions and applications of the recognized types of branch circuits, one can better navigate the requirements laid out in the NEC.
