According to the NEC®, what is the smallest gauge permitted for branch circuit conductors for appliances other than cooking appliances?

The smallest gauge permitted for branch circuit conductors for appliances other than cooking appliances, according to the National Electrical Code (NEC), is 14 AWG. This size is chosen based on the requirements for branch circuits and the maximum load they are expected to carry. For most general-purpose circuits that are designed to supply household and similar loads, 14 AWG provides adequate current-carrying capacity while ensuring safety and compliance with NEC standards.

Using 14 AWG wire allows for a safe operation up to 15 amps, which is typically sufficient for many household appliances that are not cooking-related. It also adheres to NEC guidelines that ensure that conductors are adequately sized to prevent overheating and to limit voltage drop within permissible limits. This balance between safety, efficiency, and compliance is crucial for the effectiveness of electrical installations in residential and commercial contexts.

The other gauge options, while having their own specific uses, either do not meet the requirements for non-cooking appliance circuits or are designated for different applications within the NEC. Thus, 14 AWG is the correct answer and is aligned with the prescribed standards for branch circuits serving a variety of non-cooking household appliances.
