A grommet has a body that includes a longitudinal axis and has a passageway therein. The grommet further includes a collar and a box prong. The collar extends from the body and away from the longitudinal axis. The box prong extends at least partially around the body. The grommet also includes a plurality of openings that extend through at least the box prong.

A cable sealing device including an attaching part securable to the cable; a fixation part adapted to be mountable on the attaching part; and a sealing part. The attaching part includes outer locking faces. The fixation part has inner abutment faces adapted to co-operate with the outer locking faces to axially and rotationally lock the fixation part relative to the attaching part. The sealing part includes an inner seal and an outer seal. The sealing part also includes a second securing arrangement that is configured to engage a first securing arrangement of the fixation part to axially and rotationally lock the sealing part to the fixation part.

A flange fitted around a round cylindrical condenser core of a bushing is described. The flange comprises an annular lower flange part arranged to fit around a radial shoulder of the condenser core such that a lower shoulder chamfer of the shoulder rests against lower flange chamfer of the lower flange part around the circumference of the condenser core; and an annular upper flange part fastened to the lower flange part and fits around the condenser core above an upper shoulder chamfer of the shoulder. An upper flange chamfer of the upper flange part is between an upper sealing element and a lower sealing element, forming an annular chamfer space is formed between the upper flange chamfer and the upper shoulder chamfer between the upper and lower sealing elements. The flange comprises an injection through hole for a filler material to be injected there through to fill the chamfer space.

A feedthrough module for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof contains hardwood, softwood or mixtures thereof and is intended for installation in a tested and/or approved wooden wall and/or wooden ceiling construction in buildings. The tested and/or approved wooden wall and/or wooden ceiling construction has an equal or lower burn rate than the feedthrough module. The feedthrough module has a cuboid body having edge lengths a, b, c, wherein c represents the edge length corresponding to the installation thickness (D) of the feedthrough module, and wherein the feedthrough module has a nominal burn rate of 0.7 mm/min or less.

A connection arrangement includes a first and a second assembly, and an elastically deformable locking element disposed on the first assembly. The locking element is configured to releasably interlock the two assemblies and, during mounting of the two assemblies, to deform into a mounting condition and, after completion of the mounting, to form an undercut which counteracts detachment of the two assemblies. The first assembly has a stop which is movable between an operative position, which assists in maintaining the undercut of the locking element and in which the locking element bears against the stop and/or in which the locking element is deformable against the stop, and a detachment position, in which the stop, in relation to the operative position, is spaced further apart from the locking element and in which the locking element is deformable into a detachment condition for detachment of the two assemblies.

Methods for installing electronic connections into a Factory Mutual certified cabinet may comprise providing a double walled cabinet. The double walled cabinet ay comprise an outer cabinet wall, and inner cabinet wall, and an airgap between the inner cabinet wall and the outer cabinet wall. The method may comprise the steps of including a first large hole in a surface of the outer cabinet wall and including a first small hole in a surface of the inner cabinet wall. Methods can additionally include the steps of inserting a first bulkhead fitting into the first small hole in the surface of the inner cabinet wall via the first large hole and covering the first large hole in the surface of the outer cabinet wall. Methods may additionally include the first small hole at least partially overlapping the first large hole when viewed from a plane normal to the first large hole.
