Abstract: A tool for cleaning electrically energized equipment. The tool has an elongate tubular body having a fluid input at a first end and a nozzle adapter at a second end. A first end of a nozzle is securable to the nozzle adapter. A bore extends through the body and terminates at a fluid output at a second end of the nozzle. The bore through the body, the fluid input, and the nozzle adapter has a generally circular cross-section. The fluid input has a fluid input transition to reduce the cross-sectional diameter of the bore therethrough in a direction toward the tubular body. The bore through the nozzle has a transition to alter the cross-sectional shape of the bore therethrough from generally circular to generally rectangular at the fluid output. Pressurized cleaning fluid delivered to the fluid input passes through the fluid output in a stream having a generally rectangular cross-section.
