FAQ
What is 14 AWG THHN wire used for?
14 AWG THHN wire is commonly used for branch circuits, lighting circuits, and general-purpose power wiring in residential, commercial, and industrial buildings.
How many amps can 14 AWG THHN wire carry?
practically, it is limited to 15 Amps. While the THHN insulation is technically rated to handle up to 25 Amps (at 90°C) for derating calculations, the National Electrical Code (NEC 240.4(D)) strictly requires that 14 AWG copper wire be protected by a circuit breaker no larger than 15 Amps for general wiring to ensure safety.
What is the difference between 12 AWG and 14 AWG THHN wire?
12 AWG: Thicker (2.05mm). Rated for 20 Amps. Required for kitchen, bathroom, and laundry outlets; 14 AWG: Thinner (1.63mm). Rated for 15 Amps. Used for general lighting and bedroom outlets.
