APPENDIX A
CLASS L CONNECTORS - ENGINEERING APPLICATION INFORMATION
A.1 SCOPE
A.1.1 This appendix provides engineering application information for the benefit of users of
MIL-DTL-22992, class L connectors. This appendix is not a mandatory part of this specification.
The information contained herein is intended for guidance only.
A.2 DESIGN APPLICATION
A.2.1 These connectors are a special design for power distribution using portable power cable. They
are designed for use where they will be subjected to severe impacts such as, dropping on concrete, run
over by vehicles, or subjected to extremes of field service use. They are arc quenching, if inadvertently
separated under full load. They are waterproof when mated or unmated, capped or uncapped. They are
designed to meet all OSHA and National Electric Code requirements for grounding connectors.
A.3 SAFETY SELECTIVITY
A.3.1 These connectors are designed with mating polarization for specific current rating, voltage,
frequency (Hz), phase, and grounding requirements. This prevents mating with a connector of
incompatible power characteristics.
A.3.2 These connectors are designed in the sizes based on current rating as shown in table A-I.
