Type TFN and Type TFFN (or MTW or AWM) may be used as fixture wire, machine tool wiring, or appliance wiring material as specified in the 2008 National Electrical Code. When used as Type TFN, conductor is suitable for use at temperatures not to exceed 90°C. When used as Type MTW, conductor is suitable for use in wet locations or when exposed to oil or coolant at temperatures not to exceed 60°C or dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 75°C conductor temperature per NFPA 79). Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as appliance wiring material. Voltage for all applications is 600 volts.
