Product Code:SAE J2030
Title:Heavy-Duty Electrical Connector Performance Standard
Issuing Committee:Common Tests Technical Steering Committee
Scope: This SAE Standard encompasses connectors between two cables or between a cable and an electrical component and focuses on the connectors external to the electrical component. This document provides performance requirements based upon the mechanical and electrical environment and covers applications of connectors for direct current electrical systems of 50 V or less in heavy-duty applications typically used in off-highway machinery.
