Abstract
A seal assembly for an electrical enclosure having a draw-out circuit breaker and a number of conductors is provided having a movable first seal member and a movable second seal member. The circuit breaker includes a protruding nose portion that is engaged by the first and second seal members in a manner that sealingly engages the nose portion. The arrangement of the first and second seal members and the nose portion provides for the sealing engagement to be maintained when the circuit breaker is moved from a first position in which the circuit breaker is not electrically connected to the number of conductors and a second position in which the circuit breaker is electrically connected to the number of conductors.
