WIRE AND CABLE, HOOKUP, ELECTRICAL, INSULATED, GENERAL SPECIFICATION FOR
Year: 1992
Abstract: This specification covers single-conductor, synthetic-resin insulated, electrical hookup wire and cable for use, at temperatures from −55°C to +90°C (see 6.4.3), in the internal wiring of electrical and electronic equipment. For the purpose of this specification, single-conductor hookup wire and cable are hereinafter referred to as wire.
Part numbers shall be of the following form, as specified (see 6.2.1).![ILLUSTRATION]()
The military specification designation consists of a prefix M which indicates a military specification item, and the specification number. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commanding Officer, U.S. Army Communications Electronics Command and Fort Monmouth, ATTN: AMSEL-ED-TM, Fort Monmouth, NJ., 07703-5023 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
The type of wire is identified by a three-letter or two letter symbol which indicates its application characteristics (see table I).
Note: The letter "P" designates type IP Polyvinyl Chloride (PVC) Insulation, and the letter "R" designates type IS Styrene Butadiene Rubber (SBR) Insulation.
The conductor material is identified by the letter "C" for copper or the letter "S" for copper-clad steel (see tables II and III).
The conductor size is identified by a one- or two-digit number which indicates the American Wire Gage (AWG) size (see table I).
When a range of AWG sizes is indicated herein, the sizes embraced are even-numbered. However, in the case of types MWP and MWR wire, AWG size 7 is included, and in the case of types HWP and HWR wire, AWG sizes 1, 0, and 00 are included, when applicable, in addition to the even-numbered sizes. TABLE I. Type of wire and conductor sizes.
Stranding is indicated by a single, double and triple digit number, which indicated the number of strands permitted by table II, irrespective of the number of strands actually used. For solid conductor, the number shall be a single digit number (1).
The construction of finished wire (see 6.2.1) is identified by a one-letter symbol which indicates the type of covering over the insulated wire, as follows:
The identification numbers assigned to color shall be as specified in Standard MIL-STD-681.
Intended Use: Wire covered by this specification are intended for use in the internal wiring of electrical and electronic equipment.
Part numbers shall be of the following form, as specified (see 6.2.1).

Conductor size Voltage rating Type of wire range (AWG), Application maximum inclusive, nominal characteristic (see 6.4.2) Volts, RMS ----------------------------------------------------------------------------- LWP ........... 30 to 20 General purpose 300 MWP ........... 24 to 6 1/ General purpose 1,000 HWP ........... 22 to 16 General purpose 2,500 14 to 00 600 HF ............ 24 to 16 Radio frequency 1,000 LWR ........... 30 to 20 General purpose 300 MWR ........... 24 to 6 1/ General purpose 1,000 HWR .......... 22 to 16 General purpose 2,500 14 to 00 600 1/ In sizes 10, 8, 7, and 6, the permissible constructions are limited to B, E, and H (see 1.2.1.6).
Stranding is indicated by a single, double and triple digit number, which indicated the number of strands permitted by table II, irrespective of the number of strands actually used. For solid conductor, the number shall be a single digit number (1).
The construction of finished wire (see 6.2.1) is identified by a one-letter symbol which indicates the type of covering over the insulated wire, as follows:
Symbol Covering over insulated wire A..... None. B..... Jacket. C..... Braid. D..... Shield. E..... Jacket and shield. F..... Braid and shield. G..... Shield and outer jacket. H..... Jacket, shield, and outer jacket. I..... Braid, shield, and outer jacket.
The identification numbers assigned to color shall be as specified in Standard MIL-STD-681.
Intended Use: Wire covered by this specification are intended for use in the internal wiring of electrical and electronic equipment.
