Standard Interfaces For Separable Connectors, Components & Equipment Bushings

IEEE Standard 386 defines the specific interface dimensions that 200 Amp and 600 Series elbows, inserts, junctions, equipment bushings and any mating components must conform to ensure interchangeability. The image below provides information concerning the types of interfaces supplied by Elastimold for various applications and is useful to ensure proper matching of components.
