An enclosure for a circuit breaker that includes a particle trap that is integrated into at least one foot of the enclosure. The enclosure can be configured to house a circuit interrupter and seal a dielectric insulating medium within an interior region of the enclosure. The particle trap can include an opening that extends through at least an inner side of a wall of the enclosure and into an adjacent foot such that the opening is in fluid communication with the interior region of the enclosure. Additionally, the opening of the particle trap can radially extend within both the wall of the enclosure and the foot between a first side and a second side of the particle trap.

Apparatus and method for a modular switchboard provide an adjustable length bus bridge for electrically connecting two adjacent switchboards, where the length of the bus bridge can be adjusted on site if needed. The bus bridge comprises a first set of busbars, each being electrically insulated from one another, and a second set of busbars, each being electrically insulated from one another. The first and second sets of busbars are arranged such that the busbars in the first set of busbars and the busbars in the second set of busbars are slidable relative to one another to adjust a length of the bus bridge. A longitudinal slot is formed in each busbar in either the first or the second set of busbars, or both, to accommodate a through bolt in the bus bridge when the first and second set of busbars slide relative to one another.
