To remove the exiting breaker follow instructions provide with the legacy breaker and or switchgear/
switchboard. Note that one must remove the two ½-13 bolts holding the breaker down on the drawout tray
assembly found at the front of the tray. Notice how the breaker is located at the rear by two pins passing
thru the old breaker frame. Notice how the rejection plates underneath the legacy breaker align with
rejection pins on the drawout tray assembly. Verify the correct breaker is being used. Compare the rejection
plate arrangement on the new breaker to those on the old breaker

horizontal plane.) Installation in upper compartments may not be possible with limited overhead
space or the GE switchgear hoist.
