What are the minimum required dimensions for clear work space around electrical equipment with exposed, energized parts?

The minimum required dimensions for clear work space around electrical equipment with exposed, energized parts is a critical aspect of maintaining safety in electrical installations. According to the National Electrical Code (NEC), adequate clearance is necessary to ensure that workers have enough space to safely access and work on electrical equipment without the risk of injury.

The correct answer specifies a height of 5 feet and a width of 6 inches. This dimension provides sufficient vertical clearance to accommodate the reach of an average technician while also allowing for proper access and visibility of the equipment. This height helps prevent accidental contact with energized parts when working in the vicinity. The width dimension, while narrower than other options, is still adequate for ensuring that workers can safely maneuver in the environment around the equipment.

Informed safety practices dictate these clearances to allow for potential maintenance and emergency access, reducing the risk of accidents associated with working near live electrical components. Proper clearance is vital for clear access routes and for ensuring quick evacuation from the area in case of a fault or emergency.
