strap connections to the vertical bus to 65 in-lb. It may
be necessary to remove an adjacent breaker to allow
access to the bolted connections at the vertical bus.
9. Terminal cover installation. Install the terminal cover
[1] to the breaker with thread-cutting screws [18], as
shown in Figure 34. A
3 / 8 " x 3 / 8 " relief hole must be
made in the cover if the breaker is mounted as a main
with an accessory cable (such as ground fault and
communications) leaving the load end of the breaker.

configurations available with these strap kits. When
installing these strap configurations, be sure to use
standard phase rotation, as required.
