The ETC DBEC 24/250 Insulated Protective Cap is an accessory device designed to electrically insulate and mechanically seal deadbreak bushing interfaces. Is also protects the de-energized interface from dust and damp. The cap can be used for permanent or temporary installation on 250A bushings. If there is a reserved interface in the bushings, the insulated protective cap must be used. This cap is molded of high quality EPDM insulation. When mated to a deadbreak product and the drain wire is attached to ground, the insulating protective cap provides a fully shielded insulating cover for energized deadbreak bushings.
