12 AWG THHN Cable 600V PVC Insulated Nylon Jacket Oil Abrasion Resistant Flexible Durable Suitable for Electrical Branch Circuit Feeder Wiring

12 AWG THHN Cable — 600V, PVC Insulation + Nylon Jacket, Oil & Abrasion Resistant

This 12 AWG THHN cable is a 600V rated building wire with PVC insulation and a tough nylon jacket. Rated for 90°C dry locations, it resists oil, abrasion, heat and chemicals, making it an ideal choice for conduit and raceway wiring in residential, commercial and industrial power distribution.

Key Selling Points

• 600V Rated — suitable for general-purpose branch-circuit and feeder electrical applications.
• 90°C Dry Location — high heat resistance for enclosed indoor installation.
• PVC Insulation + Nylon Jacket — durable dual-layer protection with low smoke and flame retardant performance.
• Oil & Abrasion Resistant — resists oil, grease, chemicals and mechanical wear.
• For Conduit & Raceway Wiring — flexible and easy to pull, reducing installation time.

Specification

General purpose wiring in accordance with the National Electrical Code, maximum conductor temperature of 90°C in dry locations and
75°C in wet locations, 600 volts, for installation in conduit or other recognized raceway. Also used for wiring of machine tools
(stranded), appliances, and control circuits not exceeding 600 volts.
These conductors have multiple ratings. Depending upon the product application, allowable temperatures are as follows:
• THHN or T90 Nylon- Dry locations not to exceed 90℃
• THWN-2- Wet or dry locations not to exceed 90° C or locations not to exceed 75℃ when exposed to oil
• THWN- Wet locations not to exceed 75℃ or dry locations not to exceed 90° C or locations not to exceed 75℃ when exposed to oil
• TWN75- Wet locations not to exceed 75℃
• MTW- Wet locations or when exposed to oil at temperatures not to exceed 60° C or dry locations not to exceed 90℃ (with ampacity
limited to that for 75℃ conductor temperature per NFPA 79)
• AWM- Dry locations not to exceed 105℃ only when rated and used as appliance wiring material
