ABSTRACT:
A bonding screw is pre-assembled in a distribution panel in a non-bonding position that does not bond a neutral bar within the panel enclosure to the enclosure wall. This allows an installer of the panel to select between the option of maintaining the bonding screw in the pre-assembled non-bonding position and the option of positioning the bonding screw from non-bonding position to a bonding position. A basepan is disposed within the enclosure between the neutral bar and the enclosure's back wall. The non-bonding position is defined by the screw shank thread having a threaded engagement with a through-hole in a basepan, the head of the bonding screw being spaced from the neutral bar, and the shank of the bonding screw being spaced from the enclosure's back wall. The bonding position is defined by the head of the electrically conductive part being disposed against the neutral bar and the shank being threaded into an extruded hole in the enclosure's back wall.
