nuts for enclosures, bus bar hinges, and the cable bracket.
IMPORTANT: In AC power configurations, the bottom hinges for each bus bar are
installed into cage nuts and the ends of power enclosure rack rails. In these locations, the
rails have extrusions to align the hinges and holes to accept screws. In facility DC power
configurations, you must install cage nuts to support the bottom hinges. Refer to the
template for hinge locations.
