What is the smallest size permitted for branch circuit conductors supplying appliances other than cooking appliances?

The smallest size permitted for branch circuit conductors supplying appliances other than cooking appliances is 14 AWG. This size is commonly used for general lighting and receptacle circuits. It is important to ensure that the conductor can safely handle the load without overheating or causing a fire hazard.

Branch circuits are designed to carry specific loads, and the proper sizing of conductors is crucial for safety and compliance with the National Electrical Code (NEC). The 14 AWG size is rated for a maximum of 15 amperes, making it suitable for a variety of general household lighting and outlets.

When selecting conductor sizes, one must also consider the appliance's operational current, the circuit's length, and any voltage drop that may occur, which could necessitate a larger conductor. However, for typical non-cooking appliances, 14 AWG is the minimum size, ensuring safety and efficiency in electrical systems.
