Wire barriers for separating the load wiring from the hot components of an electrical distribution panel board are integrally molded from an elastically deformable resin with a tapered elongated member projecting axially from a base member. Attachments for securing the barriers to the backpan of the panel board include at least two hook members having hook fingers projecting laterally outwa rd in divergent directions. In one embodiment, the hook members are formed in opposite sides of the elongated member and spaced from the base so that as the elongated member is inserted through an opening in the backpan from behind, the fingers gr ip the backpan and hold the barrier in place until the base is clamped between the backpan and back wall of the panel board as the backpan is installed. In another embodim ent of the invention, a pair of opposing facing hook members and a third laterally f acing hook member project axially from the base member. The barrier is tilted while th e third hook member is inserted in the aperture in the backpan. The pair of opposi tely facing hook members are then squeezed together for insertion into the opening wh ile the barrier is rotated upright, so that they also engage the backpan when releas ed.
