M27500 Wire Spec

M27500 | Mil C 27500 | NEMA WC 27500 is a mil spec wire that is commonly single or multi-conductor. M27500 cable can have both single or double shields & jackets. M27500 cable is designed to perform in the most challenging conditions and environments and are commonly used in military and aerospace applications.

Basic wire size, type, numbers of wire, shield, and jacket styles may all be spelled out under the M27500 spec.

• M27500 RC-06
• M27500 RC-09
• M27500 TG-14

The M27500 specification allows for a wide variety of construction choices. Simply build your cable from the tables below, or contact Ryan Electronics for more information.

Table 3A: M27500 Color Coding

For “preferred method” color coding, colors are stripes on white insulation (wire #1 has no stripe). Wires 11 - 15 have double stripes as indicated.

For “optional method A” color coding, colors are solid insulation color. Wires 11 - 15 have a stripe in lighter shade of base color.

Table 3B: Color Coding

For “preferred method” color coding, colors are stripes on white insulation (wire #5 has no stripe), for wires 1 - 10. For wires 11 - 15, color pairs indicate insulation of the first color, with a stripe of second color.

For “optional method A” color coding, colors are solid insulation color, for wires 1 - 10. For wires 11 -15, color pairs indicate insulation of the first color, with a stripe of the second color.

For either method, the color of the wire in a one conductor cable is white.

Table 3C: Color Coding

For “optional method B” color coding, wire insulation color is based on AWG size, with color bands per Table 4D to indicate wire number (circuit ID).

For “optional method C” color coding, wire insulation color is based on AWG size, with numbers printed on each wire to indicate wire number (circuit ID).

Table 3D: Color Coding

For “optional method B” color coding, band groups are printed on wires to indicate wire number (circuit ID).
