PRODUCT REAL SHOT

Copper Building Wire THHN

14 AWG THHN/THWN-2 – Compact and Reliable for Control Panels and Lighting

Installing wiring in crowded control cabinets demands a wire that fits without forcing. This 14 AWG THHN/THWN-2 copper building wire delivers that advantage. Its small diameter leaves space for other conductors and makes pulling through tight conduit bends easier. The PVC insulation with nylon jacket resists nicks and abrasion during installation, while the pure copper conductor ensures consistent conductivity for low-current circuits. UL83 certified with a 600V rating, it is specified for lighting branch circuits, control wiring, and small appliance loads with 15A protection. The dual THHN/THWN-2 rating accommodates both dry indoor runs and damp location installations.

FAQ

When should I pick stranded 14 AWG instead of solid?

Stranded handles vibration better and bends more easily, making it the right choice for control cabinets and equipment connections. Solid works well for fixed conduit runs.

How many 14 AWG conductors can fit in a 1/2" conduit?

Typically up to 9 conductors depending on conduit type. Always check conduit fill tables before installation.

What is the most common use for 14 AWG in commercial buildings?

Lighting circuits and control wiring. It is well-suited for low-current applications where space is limited.

Does 14 AWG maintain its rating in high-temperature environments?

Yes, when installed as THHN it is rated 90°C in dry locations. For wet locations, the THWN-2 rating provides 90°C performance.
