Apparatus and systems described herein provide for a randomly-accessible electrical busbar with a protective cover and an associated mating connector. Both the busbar and the associated mating connector have multiple, electrically conductive bristles protruding from a surface. The busbar is protected by a nonconductive fabric cover to reduce the risk of a person from accidentally contacting the electrically conductive bristles. A connection is made between the mating connector and the busbar by the bristles of the mating connector penetrating the protective fabric cover and interdigitating with the bristles of the busbar.
