North Carolina ElectriCities Intermediate Lineworker Practice Exam

MAD is used to determine safe clearance from energized equipment based on which factors?

Voltage level and task Weather conditions Time of day Equipment color

Correct Answer:

Voltage level and task

Explanation:

Minimum Approach Distance is the closest you can safely approach energized equipment without risking shock or arc flash. The two factors that set this distance are the voltage level of the system and the task you’re performing. Higher voltages create a greater potential for electrical arcing, so more clearance is needed. The specific task matters because some actions (like connecting, testing, or manipulating equipment) have a higher chance of causing arcing or unwanted contact than simple observation, so they require larger clearances. Weather, time of day, and equipment color don’t determine MAD, though weather can affect other safety aspects.
