As a diesel electrician, your job is to install, maintain, and repair diesel electrical systems, which in this case generally refers to electrical systems powered by one or more diesel generators. In this role, you may ensure user safety by checking for wear and tear on the system, patrol each site, report noted issues, and otherwise maintain the entire system. Fulfilling the duties and responsibilities of a diesel electrician often involves working with both mechanical and electrical systems, making this job similar to a cross between regular electricians and engine mechanics. Some diesel electricians work in moving environments, such as on boats or trains.
