Lifting Circuit Breaker
CAUTION
DO NOT ATTEMPT TO LIFT CIRCUIT BREAKERS WITH ORDINARY
CRANE HOOKS, ROPES, CHAINS OR OTHER SUCH DEVICES. FAILURE
TO FOLLOW THIS CAUTION COULD RESULT IN DAMAGE TO VITAL
PARTS SUCH AS ARC CHUTES, BARRIERS AND WIRING OR THE
ENTIRE CIRCUIT BREAKER.
To closely examine, install or just become more familiar with
the circuit breaker, carefully lift and place the circuit breaker on
a solid work surface capable of handling the circuit breaker’s
weight (
Table 2
) or on the captive drawout extension rails of
the breaker compartment (
Figure 5
) . This is accomplished by
using the appropriate lifting yoke and lifter . The lifting yoke
consists of two steel hooks specially shaped to hook under
the integral molded lifting handles on both sides of the circuit
breaker (
Figure 5
) . Every effort should be made during lifting to
minimize circuit breaker swing and tilt .
If the circuit breaker is to be lifted onto compartment extension
rails, follow the instructions on page 11 entitled “Installing
Drawout Circuit Breaker .”
