G u id e Form S pecifi cations
General
The individually mounted low voltage power circuit
breaker shall consist of an electrically and mechanically
trip-free circuit breaker element.
The circuit breaker shall be of the draw-out type capable
of being racked to the disconnect position with the door
closed .
The circuit breaker shall meet ANSI C37. 1 3 , C37 . 1 6 and
C37 .50 and be UL listed.
I nterlocks will be provided to prevent connecting or dis­
connecting the circuit breaker u nless the breaker is open.
The breaker shall be prevented from being closed during
any racking operation. A test position shall be provided to
permit operating the breaker while it is disconnected from
the power circuit.
