This SAE Aerospace Information Report (AIR) is intended to provide guidelines to tightening methods and torque values as applied to electrical connectors, related hardware and switches, relays, circuit breakers and A-A-59125 type terminal boards. The connectors and associated hardware discussed herein, are typically manufactured from aluminum alloy, high grade engineering thermoplastics or corrosion resistant steel and typically plated with a protective/conductive coating. These guidelines may be used where no rules have been mandated either contractually or otherwise.
Rationale: Revision is required to incorporate torque values for attaching electrical wiring devices to switches, relays, circuit breakers and A-A-59125 type terminal boards. These torque values are currently listed in non-current ARP1928A and need to be in an active document.
