Description
By applying electrical theory, electronic fundamentals, and refrigeration concepts, Utilities Systems Technicians perform organizational and intermediate repairs on electric motors, electronic modules, motor control circuits, electric power generation equipment, field refrigeration equipment, environmental control units, and electrical systems repairs of engineer equipment (to include ground equipment). Additionally, they install and operate field refrigeration units and environmental control units and thus must be certified by the environmental protection agency (EPA) to handle and recover hydro chlorofluorocarbons (HCFCs) and chlorofluorocarbons (CFC). Corporals through staff sergeants are afforded the opportunity to attend a skill progression course. The Advanced Utilities Systems Technician Course (M03A212) provides in-depth instruction in diagnostics and repair of complex electrical circuitry and integrated electronics, identification of personnel to support deployed equipment, infrastructure reconnaissance, and maintenance operations. An apprenticeship program, leading to U.S. Department of Labor certification as a journeyman worker, is available under the United Services Military Apprenticeship Program (USMAP).
