ABSTRACT:
An enclosure for electrical switchgear is a box like structure made up of side panels, front and rear panels and external panels. The panels define chimneys which are connected to the enclosure via apertures at their lower ends. Thus if the gas filled circuit breaker chamber explodes as a result of a fault developing, the enclosure is relieved of the resulting pressure generated by the expanding gases by venting to a ventilation system via the apertures and the chimneys.
