Step 5:
For a breaker
with
an 1150 trip unit only, find the rust-
colored connector in the vicinity of where the spring release
device is mounted. This two-piece connector will easily separate
by pulling apart on the two ends. Insert the spring release
wire marked “B12” into the connector until it snaps into place.
Re-connect the rust-colored connector. Insert the spring release
wire “B13” into the breaker secondary block “B” at position 13.
