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 90ºC
• THWN-2- Wet or dry locations not to exceed 90° C or locations not to exceed 75ºC when exposed to oil
• THWN- Wet locations not to exceed 75ºC or dry locations not to exceed 90° C or locations not to exceed 75ºC when exposed to oil
• TWN75- Wet locations not to exceed 75ºC
• MTW- Wet locations or when exposed to oil at temperatures not to exceed 60° C or dry locations not to exceed 90ºC (with ampacity limited to that for 75ºC conductor temperature per NFPA 79)
• AWM- Dry locations not to exceed 105ºC only when rated and used as appliance wiring material
• ASTM B3: Annealed or soft copper wires.
• ASTM B8: Concentric Layered Copper Stranded Conductors.
• ASTM B787: 19 Wire Combination Unilay-Stranded Copper Conductors for Subsequent Insulation.
• UL 83: Wires and cables insulated with thermoplastic material.

+Allowable ampacities shown are for general use as specified by the 2014 Edition of the National Electrical Code Sections 310.15 and 240.4(D). Unless the equipment is marked for use at higher temperatures the conductor shall be limited to the following per NEC 110.14(C):
75ºC - When terminated to equipment for circuits rated over 100 amperes or marked for conductors larger than 1 AWG.
90ºC - THHN dry locations and THWN-2 wet or dry locations for ampacity adjustment purposes using NEC section 310.15.
