Frame Installation Instructions

Stationary, Moveable, and Fixed-Mounted Drawout Elements

To correctly engage the moveable drawout element with the

racking mechanism, the crank pins on the sides of the move-

able drawout element must be in the Unlocked position as

illustrated and the release lever must be in the Up position.

During shipping and handling, the crank pins may have rotated

out of position. If so, rotate them to the correct position. The

moveable drawout element may now be moved/racked into

the stationary drawout element. Racking instructions start on

page 18.

Installing Fixed-Mounted SB Breakers

Prepare the switchboard for installation of the SB breaker in

accordance with the outline drawings at the end of this sec-

tion. The outline drawings are located in the Outline Dimension

Drawings section starting on page 36. The locations of the

mounting holes and the recommended screws are depicted

on the drawing. All four, six or eight mounting screws will be

used to secure the breaker to the switchboard.

Carefully uncrate the breaker and remove all packing material. If

the breaker is secured to a pallet, remove the securing device.

Lifting straps should go between the stabs.

Attach the lifting straps as illustrated. The breaker should not

be lifted by the primary stabs; the lifting straps should go

between the stabs. In this arrangement the breaker may be

easily balanced while it is being lifted by a crane or hoist.

Lift the breaker into position and secure it with 4 mounting

screws for 1200A and 2000A frame sizes, 6 mounting screws

for 3200A frame size, and 8 mounting screws for the 5000A

frame size torqued to 13–15 ft-lbs. Remove the lifting straps.
