Abstract
A modular bucket assembly of a low voltage switchgear includes a box shaped bucket having an interior bucket side wall, an exterior bucket side wall with vents in a first periphery, a bucket rear wall, a bucket top wall and a bucket bottom wall. All of the bucket walls define an auxiliary compartment of a switchgear cabinet. The vents in the exterior bucket side wall define an arc gas venting passage in communication with an interior of the auxiliary compartment for exhausting arc gasses to an exterior of the cabinet. The modular bucket assembly further comprises a metal enclosure mounted on the bucket bottom wall. The metal enclosure has a side opening with a second periphery such that the second periphery overlaps the first periphery of the exterior bucket side wall. The metal enclosure is configured to house direct power connected devices and protective fuses and withstand arc fault pressures.
