According to the NEC®, what is the smallest size permitted for branch circuit conductors suitable for supplying non-cooking appliances?

The National Electrical Code (NEC) establishes specific guidelines for the sizing of conductors to ensure safe and efficient operation of electrical systems. For branch circuit conductors that supply non-cooking appliances, the NEC permits a minimum conductor size of 14 AWG (American Wire Gauge).

This size is commonly used for 15-amp circuits, which are typical for general lighting and receptacle outlets in residential settings. When considering non-cooking appliances, which can include devices like vacuum cleaners or small power tools, it's important to ensure that the conductor size can handle the potential load without overheating and causing a safety hazard.

Using 14 AWG ensures compliance with the NEC requirements while providing adequate current-carrying capacity for most standard residential applications. Larger sizes like 12 AWG or 10 AWG are permissible but not necessary unless higher current capacities are anticipated or required by specific applications. Meanwhile, 16 AWG is not suitable for general branch circuits as it does not meet the minimum requirements set forth by the NEC for these applications.
