Circuit breaker positioning
Magnum PXR and PD-SB drawout circuit breakers have four
normal positions:
•
REMOVE (withdrawn) (
)
•
)
•
TEST (
)
•
CONNECT (
)
The REMOVE position is a position outside the compartment
on the cassette’s drawout rails where the circuit breaker is not
engaged with the levering mechanism . The DISCONNECT,
TEST, and CONNECT positions are reached by means of the
levering mechanism .
With the breaker solidly positioned on the cassette’s extension rails
and the levering-in mechanism in the DISCONNECT position, carefully
and firmly push the circuit breaker into the compartment as far as it
will go . The outer (recessed) portion of the circuit breaker faceplate
should align with the GREEN target line (labeled DISC) on the inside
top left wall of the cassette (
) .
