Reauirements. The connectors shall be rated for a three pole, three phase ungrounded 600 volt, Delta electri
3、cal distribution system. The connectors shall be rated for an alternating current (ac) load of 500 amperes, 60 Hertz, and shall be capable of attachment to a 3/C THOF-500 MCM Navy cable. The connectors shall be designed for an in-line, quick lock slide sleeve, type of connector. The connectors shall
4、, as a minimum, consist of mating male and female plugs, protective caps with chains, grommets, clamps, couplings, set screws, sleeves, raceways and other hardware parts as needed to effect a completed connection. The connectors shall be of a design that allows field assembly, and shall be manufactu
5、red to be water tight, when assembled with mating receptacle or protective cover cap. 2. Material. The connectors shall be constructed of molded neoprene and shall have rubber coated manganese bronze shells. The current carrying contact material shall be copper conforming to ASTM B-301, alloy no. C1
6、4500 or C18700. Current carrying parts shall be silver plated, in accordance with Type II or Type III, Grade A, of Federal Specification QQ-S-365.

Contract number c. Serial number (alpha-numeric sequence at option of contractor) d. Field assembly instru
9、ctions e. Phase rotation identification (A,B,C) Marking shall be on identification/information plates or directly on the item at the option of the manufacturer. Qualitv assurance Drovisions. 1. 2. 3. 4. 5. Responsibilitv for tests. Unless otherwise specified in the contract, the contractor is respon
10、sible for the performance of all test requirements as specified herein. Unless disapproved by the Government, except as otherwise specified in the contract, the contractor may use his own or any other facilities suitable for the performance of the test requirements specified herein. Qualitv conforma
11、nce tests. The quality conformance tests shall be performed on sample connectors selected in accordance with the inspection lot and sampling requirements. This inspection shall include examination and operational tests as specified herein. Inspection lot. All units offered to the Government at one t
12、ime shall be considered a lot for purposes of inspection, A sample unit shall be one complete connector (male and female). Examination. Each sample selected in accordance with the inspection lot and sampling requirements shall be examined for compliance with the salient characteristics requirements
13、specified herein. This element of inspection shall encompass all visual examinations and dimensional measurements, Noncompliance with any specified requirements or presence of one or more defects preventing or lessening maximum efficiency shall constitute cause for rejection. Contact resistance test
14、. Mated units shall be tested to comply with method 307 of MIL-STD-202. The connectors shall show no Contact resistance above the limits shown in table I. The following details shall apply: a. Test current: 300 Amperes (A) through each bus lug. b. Number of measurements: Three (minimum) to determine

17、lternating current (ac) b. Magnitude of voltage: 2500 volts (V) root mean square (rms) c. Points of application: The potential shall be applied between each phase and metal part and between each phase and all adjacent phases. 7. Pull-out strength test. Individual connectors, attached to the 3/C THOF
18、-500 MCM Navy cable, shall have sufficient force applied to pull the cable out of the connector. The force required to pull out shall not be less than 1500 pounds. 8. Engaging and disengagina forces test. Engaging and disengaging forces shall not exceed 50 pounds. Contractor certification. The contr
19、actor shall certify, and maintain substantiating evidence, that the product offered meets the salient characteristics of this CID and that the product conforms to the producers own drawings, specifications, standards, and quality assurance practices. The government reserves the right to require proo
