3. Locate the proper side of the interior to mount the straps.

Locate the side of the panel interior bus at which the
distance from the vertical bus face to the inner face of the
bus support rail is 2.75 inches, as shown in Figure 3. The
circuit breaker straps will be mounted on this side of the
vertical bus. The assembly views show the 2.75-inch
distance on the right. When the 2.75-inch distance is on
the left, the proper view is upside down.
