Section 2: Receiving, handling, and installation
2-4 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 cir-
cuit breaker’s weight (Table 2-1) or on the captive drawout
extension rails of the breaker compartment. This is accom-
plished 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. Every effort should be made during
lifting to minimize circuit breaker swing and tilt.
If the circuit breaker is to be lifted onto compartment exten-
sion rails, follow the instructions in Section 2-7, “Installing
drawout circuit breaker.”
2-5 Circuit breaker inspection
All circuit breakers, once removed from their shipping
containers, should be visually inspected for any obvious
damage.
The current rating of the rating plug installed in the trip unit
should match the current rating of the sensors mounted
on the lower primary stabs of the circuit breaker. Check
to make sure that this match exists. The sensor rating can
be viewed through the viewing windows at the rear of the
circuit breaker (Figure 2-2).
