FIG. 4A is a perspective view of electrical enclosure 100 with circuit board 120 positioned in housing 130; FIG. 4B is a close up perspective view of portion 4B shown in FIG. 4A; and FIG. 4C is a close up perspective view of portion 4C shown in FIG. 4A. Circuit board 120 is shown positioned within side walls 132, 134, 136, and 138 of housing 130. Backplane connector interface 133 is shown extending through opening 181 above side wall 134. In FIG. 4B, protrusion 140 is shown inwardly extending from side wall 132 and cutout 160 of circuit board 120 extends around an exterior of protrusion 140. Connector through hole 125 in circuit board 120 is shown near cutout 160 and a capacitor lead 170 is shown extending through an opening in circuit board 120. Similarly, in FIG. 4C, protrusion 150 is shown inwardly extending from side wall 136 and cutout 162 of circuit board 120 extends around an exterior of protrusion 150. Connector through hole 127 in circuit board 120 is shown near cutout 162 and a capacitor lead 172 is shown extending through an opening in circuit board 120.
