Specifies requirements for the safety, performance and interchangeability of sockets rated 500 V, 125 A a.c. and associated components; also for plug-in meters and devices intended for insertion in two orientations (normal and 90 degrees anticlockwise), or in only the normal orientation.

This Standard specifies safety, performance and interchangeability requirements for sockets rated 500 V, 125 A, for plug-in devices, for retaining covers, and for blanking plates. This Standard also specifies standard connection arrangements (see Appendix A), and standard arrangements for multiple sockets (see Appendix B).NOTES:1 Where a socket is to be used with a device rated at more than 100 A, the socket should be wired with a minimum of 35 mm copper cable to terminals A and L.2 To facilitate the specification and purchase of sockets and other components, the Standard lists information which should be supplied with enquiry and order (see Appendix C).
