3.4 Lifting of Circuit Breakers
Always consider the center of gravity of the breaker
may induce the breaker to tip over.
If a breaker has a single hole on each side and a
picture of a lifting hook, as shown in Fig. 3-1, use lifting
straps and hooks to attach to the circuit breaker at
those points to lift the circuit breaker. When the circuit
breaker has a single lifting hole with two additional bolt
holes, use the lifting attachments shown in Fig. 3-2 to
attach to the breaker. Then attach the lifting straps and
hooks to the attachments. When using any lifting
equipment, remove the lifting equipment before
installing the circuit breaker into the switchgear.
