The access frame includes a mount selectively engagable with the electrical enclosure adjacent an edge of an enclosure sidewall, support legs attached to the mount and extending therefrom and an elongate support bar supported in spaced apart relation to an edge of an enclosure sidewall by the support legs. The access frame defines an access opening extending between the support legs and the support bar and the sidewall edge. The access opening facilities installing wire clamps having a wire clamp passageway in knockout apertures defined in the enclosure side wall.
