Abstract
A method and a door arrangement for a switchgear enclosure, with the enclosure having a top and bottom panel, a back panel and two opposing side panels. The enclosure includes an interior framework supporting a draw-out circuit breaker. The door arrangement comprises a front extension coupled to the enclosure. An exterior door is pivotably mounted in an offset position to the front extension and configured to move from one of a closed position and an open position on one side of the enclosure. The breaker door is pivotably mounted to the interior framework and configured to move from one of a closed position and an open position on another side of the enclosure and move clear of the offset exterior door.

A door arrangement for a switchgear enclosure, the enclosure having a top and bottom panel, a back panel and two opposing side panels and including an interior framework supporting a draw-out circuit breaker, the door arrangement comprising:
- a front extension coupled to the enclosure;
- an exterior door pivotally mounted to the front extension at an offset exterior door frame post and configured to move from one of a closed position and an open position on one side of the enclosure;
- and
- a breaker door pivotally mounted to the interior framework and configured to move from one of a closed position and an open position on another side of the enclosure and clear of the offset exterior door frame post.
A switchgear enclosure for a draw-out circuit breaker, the enclosure comprising:
- structure having a top panel coupled to a bottom panel with a back panel coupled to two opposing side panels defining an interior space;
- a framework mounted in the interior space of the structure and configured to support a circuit breaker;
- a front extension coupled to the structure;
- an exterior door pivotally mounted to the front extension at an offset exterior door frame post and configured to move from one of a closed position and an open position on one side of the structure;
- and
- a breaker door pivotally mounted to the interior frame work and configured to move from one of a closed position and an open position on another side of the structure and move clear of the offset exterior door frame post.
A method of housing a circuit breaker, the method comprising the steps of:
- providing an enclosure defining an interior space;
- providing a framework configured to support the circuit breaker;
- mounting the framework in the interior space;
- providing a front extension;
- coupling the front extension to the enclosure;
- providing an exterior door configured to move from one of a closed position and an open position;
- providing an offset exterior door frame post;
- mounting the exterior door on the offset exterior door frame post at one side of the enclosure;
- providing a breaker door configured to move from one of a closed position and an open position;
- mounting the breaker door on another side of the enclosure;
- mounting the circuit breaker on the framework.
