Figure 4.16 depicts the breaker lifting device assembled on
indoor equipment. When supplied with indoor equipment, the
breaker lifting device is shipped in a separate carton
completely assembled, Figure 4.17.
WARNING: The maximum lifting capacity of the
breaker lifting device is 500 pounds. The breaker lifting
device is design specifically to raise or lower EntelliGuard

beam referenced in Table 6.1. Use of the circuit breaker
lifting device for other functions is not recommended.
Before attempting to install the breaker lifting device
assembly onto the switchgear equipment, it is necessary to

The breaker lifting device can be lifted into position on top of
the switchgear so that the end with two rollers is toward the
