A utility cross arm assembly for supporting electrical wires from a utility pole. The entire assembly is constructed from insulative materials. It is provided with easily replaceable wire support members or protective caps to enhance convertibility from a single phase delivery configuration to a three phase delivery configuration. The assembly frame provides left and right cross arms with an upper support neck. Various arms and legs provide structural support and a way to mount the assembly to the utility pole. Large open spaces between the arms and legs provide a lightweight construction with low air resistance upon mounting to the utility pole.
