Maintenance 7 - 3
Open
Distribution
Breaker
A distribution breaker which should be closed may be in the
open position for one of three reasons.
1. A distribution breaker may have been inadvertently turned
off manually. If this is the case, follow the proper
procedure to restore power to the load equipment. If a
distribution breaker is no longer needed, it may be
unplugged from the panel or left in the OFF position.
2. A distribution breaker may trip due to a short circuit in the
load equipment or wiring. The fault must be cleared before
resetting the breaker, except when the trip is suspected to
be caused by inrush current during equipment start up. The
handle will be between the ON and OFF positions when
the breaker has tripped due to overcurrent.
3. A circuit breaker may fail such that it cannot be reset.
Replace a failed distribution breaker per procedure on page
7-5.
