Specifies standard shapes and dimensions for palm terminals for a range of assigned standard current ratings up to 3150 A for copper and 5000 A for aluminium, and dimensions for cylindrical terminals with assigned current ratings up to 3150 A. Appendices deal with preparation of joint surfaces and the design of bolted connections.

This standard specifics dimensions and configuration for terminals intended for use on indoor and outdoor switchgear assemblies for alternating voltages above 1 kV such as are employed in connection with the generation, transmission and distribution of electric power. It also applies to the ancillary equipment used in conjunction with the switchgear.
