Step 16: Installing the Retrofitted Breaker
in the Cell
Do not leave the Breaker in an intermediate
position in the switchgear cell. Always leave
it in the CONNECTED, DISCONNECTED, or
(Optional) TEST position. Failure to do so could
lead to improper positioning of the Breaker and
flashover, causing death, serious personal in-
jury, and / or property damage.
NOTE: It is the responsibility of the Retrofitter
to insure proper Breaker / Cell fit. When
racking the Breaker into the Connected
position, the Retrofitter MUST FOLLOW BOTH
the manufacturer’s instructions and the
customer’s safety standards and procedures
for racking a Breaker into the Connected
position.
A. With the Breaker in the Open position and the
springs discharged, slowly rack the Breaker into
the Connected position, making sure there is no
interference or binding. The Breaker should rack
smoothly and without mechanical interference
between any Breaker and Cell parts. The
Retrofitter will feel some resistance when the
primary fingers connect onto the stabs of the
Cell. This is normal.
However, if any unusual resistance is detected
that could be abnormal interference between
the Breaker and Cell parts, stop immediately
and move the Breaker out of the Connected
position. Examine what is causing the
interference and correct the situation.
