An electrical system for use in a raceway includes a power cable and a junction block. The junction block includes junction block halves configured to form opposing halves of the junction block, a plurality of bus bars arranged within a bus bar cavity, and a hinged connector arranged on a face of a first of the junction block halves. The junction block halves are coupled to define a bus bar cavity within the junction block. Each of the bus bars are electrically coupled to a conductor of the power cable. The hinged connector is arranged opposite a second junction block half such that a portion of the hinged connector is rotatable about an axis that is parallel to a face of the first junction block half. The power cable is coupled to the junction block via the hinged connector.
