6.3 Shielding Connectors shall have an electrically conductive shield and, where required, shall have provision for connecting an external ground to the shield. Except for nonelastomeric components, connectors shall meet the requirements of IEEE Std 592.76.4 Interchangeability 6.4.1 Complete interchangeability a) Complete interchangeability implies that parts from one manufacturer when mated with parts of another manufacturer meet all the applicable requirements of this standard. b) Complete interchangeability is demonstrated when: 1) A part meets the design test requirements when tested with any mating part meeting the dimensional requirements of this standard. 2) In addition, 200 A loadbreak connectors must demonstrate conformance with switching (7.7) and fault close (7.8) test requirements when tested with intermixed bushings and elbows of different manufacturers.
