What is the minimum vertical rise for work space above energized parts?

The minimum vertical rise for work space above energized parts is essential for ensuring safety during electrical work. A vertical space of 5 feet is the standard requirement to provide adequate clearance for personnel working around energized components. This height helps to reduce the risk of accidental contact with live parts and allows technicians to operate safely without the risk of coming into contact with potential hazards.

Having this minimum clearance also facilitates the use of appropriate tools and equipment, ensuring that workers remain at a safe distance from energized conductors and devices. This regulation emphasizes a precautionary approach to handling electrical installations, ultimately contributing to safer working conditions in environments involving electrical systems.

Other heights such as 4, 6, or 7 feet may not meet the established safety guidelines that the National Electrical Code (NEC) specifies, which are designed to protect workers from electrical hazards.
