Machine Tool Wire (MTW)

Machine Tool Wire (MTW)

Description

Machine Tool Wire (MTW) consists of stranded, soft annealed copper conductors insulated with Polyvinylchloride (PVC). MTW is UL rated for 600 volts. #10, 12, and 14AWG are 19 strands, all others are “highly flexible” stranding constructions. The Appliance Wiring Material (AWM) constructions may be solid or stranded and are available in 1000 V ratings.

Canadian Standards Association (CSA) listed AWM-IA (Class I Group A) and TEW products are 600 V FT-1 rated. All our standard products are compliant and multi-listed as types TW, THW, MTW, TEW, and the applicable AWM Style Number.

Application

Type MTW/TEW is most often found in general purpose wiring circuits, for machine tool wiring and the internal wiring of appliances, such as 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. Larger MTW products are marked AWM 1028 or 1283. The governing standard for application of these products is the National Fire Protection Association (NFPA) Publication #79.
