TW/THW Wire

TW/THW is most often used in general purpose wiring circuits, for machine tool wiring and the internal wiring of appliances. Common applications include control panels, wiring for refrigeration equipment, air-conditioning equipment, control wiring of machine tools, automatic washers, etc. It can be used in dry locations up to 90°C (ampacity is limited to 75°C conductor temperature per NFPA 79); or wet locations or other applicable locations when exposed to oil or coolant at temperatures up to 60°C. CSA Type TEW rating permits use in dry locations up to 105°C; or wet locations or other applicable locations when exposed to oil or coolant at temperatures up to 60°C. Our standard circuit size (#10, 12, 14 awg) products are marked Style 1015,Maximum voltage rating 600 V
