Abstract
A touch safe electrical panel (100) includes a bus (110) having a branch connector (130) with a vertical stab (132) and a touch safe connection assembly (150). The assembly includes a dielectric housing (152) for the stab. The housing (152) includes a slot (180) through which to receive the stab, and an opening (190), arranged away from the slot, through which to receive a terminal of a plug-on circuit breaker configured to engage the stab. A dielectric barrier (170A, 170B) is arranged in the housing between the slot and the opening. The barrier partially blocks a passage way between the opening and the slot to prevent direct user contact of the stab while enabling the terminal to pass through the partially blocked passage way and engage the stab.
