1.1 These requirements cover all-thermoplastic Type MTW, 600-V, machine-tool wires and cables for use as specified in the National Electrical Code (ANSI/NFPA 70), and in the National Fire Protection Association Electrical Standard for Industrial Machinery (ANSI/NFPA 79). These wires and cables comply with a flame test and are for use at 90°C (194°F) and lower temperatures in dry locations and at 60°C (140°F) and lower temperatures where exposed to moisture, oil, or coolants such as cutting oils and the like.

A conductor is appropriate for use with a cross-sectional area that does not correspond to one of the AWG or kcmil sizes in when the finished wire or cable complies with the marking requirement in 2 and with each of the following:

a) The conductor shall have a dc resistance that is not larger than the resistance determined by interpolation (by cross-sectional area) between the resistances of the next larger and smaller sizes shown in the applicable or .

b) The number of strands, the thicknesses of insulation, the thickness of any nylon jacket, and other particulars shall comply with the requirements applicable to the next smaller size shown in .

1.2 The two single-conductor constructions covered are described in . Both are PVC-insulated and one includes a nylon jacket over the insulation. These single-conductor constructions may be optionally shielded and jacketed. The multiple-conductor constructions covered consist of assemblies of these single-conductor constructions (sizes and styles may be mixed) enclosed by a PVC jacket.
