Ergonomics Specification for Electrical Connections USCAR25-2

This document describes the design relative to assembly force, and hand clearance guidelines for conventional hand-plug, mechanical assist and twist lock electrical connectors, as well as Connector Position Assurances (CPAs). The minimum values associated with this design guide need to be evaluated against other critical characteristics that impact quality, efficiency and other traits of assembly feasibility.

All possible designs and applications could not be anticipated in creating these guidelines. Where there are questions of adherence to this document, such as use of an “off-the-shelf” design, always consult the responsible Ergonomics Department.
