Abstract: Electrical enclosure assemblies, electrical service enclosures, and methods of assembling an electrical enclosure assembly are presented herein. An electrical enclosure assembly for housing electrical components of an electrical distribution system is disclosed. The enclosure assembly includes a plurality of sidewalls interconnected to define therebetween a mounting space within which are mounted the electrical components, and define at one end thereof an open endface. An endwall guide extends from one or more of the sidewalls into the mounting space. The endwall guide includes a plurality of elongated slots, a plurality of projections, or both. The enclosure assembly also includes an endwall configured to at least partially close off the open endface. The endwall includes a plurality of elongated slots, a plurality of projections, or both. Each of the projections is configured to fit into and secure with a respective elongated slot to thereby removably mount the endwall to the sidewalls.
