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.

[ What is claimed is:] [1.] An electric distribution panel comprising:a walled enclosure comprising an electrically conductive wall forming a portion of the enclosure;an electrically conductive neutral bar disposed within the enclosure;an electrically non-conductive part disposed between the neutral bar and the wall to place the neutral bar in a non-bonded relationship to the wall;a through-hole in the neutral bar;a through-hole in the electrically non-conductive part in underlying registry with the through-hole in the neutral bar;an electrically conductive part adapted for optional bonding of the neutral bar to the wall, the electrically conductive part comprising a head and a shank extending distally from the head, the shank comprising a thread;wherein the electrically conductive part is pre-assembled to the non-conductive part in a non-bonding position not bonding the neutral bar to the wall so as thereby to allow an installer of the panel to select between the option of maintaining the electrically conductive part in the pre-assembled non-bonding position and the option of positioning the electrically conductive part from non-bonding position to a bonding position wherein the electrically conductive part bonds the neutral bar to the wall;wherein the pre-assembled non-bonding position is defined by the shank thread having a threaded engagement with the through-hole in the electrically non-conductive part, the head of the electrically conductive part being spaced from the neutral bar, and the shank being spaced from the wall; andwherein the bonding position is defined by the head of the electrically conductive part being disposed against the neutral bar, and the shank being disposed against the wall.
