the inspector to determine compliance with applicable standards and to
determine if hazardous or potentially hazardous conditions exist, with
attention to safe access, guards, equipment condition, fire suppression
systems, combustible materials, fire protection, condition of trailing or power
cables, circuit breaker settings, cable conduit, braking mechanisms, reflective
materials, and safety devices. If an inspector finds that wiring of electric
equipment is in a rundown condition, with many violations existing on one
unit of equipment, and if there is evidence that thorough and complete
examinations are not being made or that the required tests are not being made,
a citation should be issued under § 75.512 (Electric equipment; examination,
