  • Green colour coding identifies ground or equipment-bonding circuits
  • 500 ft reel supplies enough length for whole-house wiring
  • Nylon jacket protects conductor from damage during pulling

Application Scope

This THHN building wire is designed for general-purpose indoor wiring projects such as control circuits and appliance connections. It carries electrical current from a power source to outlets or light fixtures in commercial, industrial, and residential properties. The wire is typically run through conduit, cable trays, or raceways. It is not suited for direct burial or outdoor exposure without additional protection.

Insulation Properties

The thermoplastic high-heat-resistant nylon jacket provides a durable barrier that resists abrasion and protects against shock. It shields the underlying thermoplastic insulation and solid metal conductor from physical damage during installation and use. This construction supports standard indoor thermal environments without special cooling requirements. No noise or power-draw characteristics apply to this passive component.

Sustained Operation

Under continuous load the nylon jacket maintains its protective qualities and the solid conductor delivers consistent conductivity. The 500 ft length allows extended runs without splices, reducing potential failure points in long circuits. Performance remains stable within the wire's rated temperature and voltage limits for the duration of the installation. The 14 AWG gauge sets the safe current-carrying capacity for sustained use.

Questions about this item

How is the 14 AWG solid THHN wire pulled through conduit without damaging the nylon jacket?

Feed the wire slowly by hand or with a fish tape, keeping bends gradual so the nylon jacket does not kink or scrape against sharp conduit edges.

What maintenance or replacement will the green THHN building wire need over time?

Inspect periodically for cracked insulation, discolouration, or exposed copper; replace any damaged sections rather than taping over them.

What limit appears first when the 14 AWG solid conductor runs continuously at full load?

The solid copper conductor reaches its ampacity ceiling before the THHN insulation hits its temperature rating, so voltage drop and heat become the limiting factors.
