Abstract
A method for passing an electrical cable through a hole in a housing of a unit of electrical equipment is provided. The method may include: fitting onto the cable a tubular, mushroom-shaped male member comprising a stem with a threaded portion and a portion with enlarged head; inserting into the hole the cable having the male member fitted thereon extending through said hole with said portion with enlarged head abutting against the periphery of the hole externally to the housing and said threaded portion protruding inside the housing; and retaining said male member in the hole by coupling with said threaded portion that protrudes inside the housing an annular female member in the form of a nut co-operating with the periphery of the hole inside said housing to counter the movement of the female member with respect to the housing.
