Front Doors - GE AKD-20 AR Installation And Maintenance Manual

DEH-41473

Front Doors

The front access doors, auxiliary and circuit breaker doors, on
all AR switchgear are hinged and equipped with a self-
latching system (Figure 8.4). To open the door, rotate the
handle clockwise. To close the door, push on the outside of
the door directly behind the self-latching mechanism (Figure
8.6).
To verify that the front door has latched, pull on the door
handle without rotating the handle. Both the upper and lower
door latches should keep the door in place.
Any front access door that is required to be closed to
maintain the integrity of the arc resistant enclosure is marked
with a warning label (Figure 8.5).
The AR switchgear is rated per IEEE standards for a type 2B
class rating. The type 2B classification allows the auxiliary
door, unless otherwise marked, to be opened without
impacting the arc resistant rating of the enclosure.
WARNING: The breaker compartment door must be
closed and latched to maintain the integrity of the arc
resistant enclosure. The breaker compartment door should
not be opened when the circuit breaker is closed and in the
connected position when the equipment is energized.
WARNING: When a circuit breaker is removed from its
compartment. The future cassette barrier and the future
breaker door cover must be installed and the circuit
breaker compartment door closed and latched to maintain
the integrity of the arc resistant enclosure.
