SECTION 3. DISASSEMBLING THE
BREAKER

A Westinghouse® DB-15 breaker conversion consists of
removing certain breaker components and replacing
some of them with the new GE conversion kit
components. After the GE conversion kit is installed, the
breaker is ready for testing and return to service.

The first step is to remove the breaker to a clean, well-
lighted work bench and place it upright, so that both the
front and back are easily accessible, as shown in Figure
1.

1. Remove and save the load terminal draw-out fingers

on all draw-out breakers. They can be easily
removed by inserting a flat-blade screwdriver under
the back edge of the top finger and prying the fingers
back, as shown in Figure 2.
