What size must the accessible hand hole in high poles be?

The size of the accessible hand hole in high poles, specified as 2 inches by 4 inches, is outlined in the National Electrical Code (NEC) to ensure safe and adequate access for maintenance and inspection. This size is designed to provide enough room for workers to maneuver tools and equipment effectively while maintaining safety standards.

Having a standard size for access openings is crucial for consistency across installations, allowing technicians to work without the risk of damaging equipment or causing safety hazards. The 2 inches by 4 inches dimensions strike a balance between being large enough for practical use while still being manageable and unobtrusive.

Other sizes, such as those that are either smaller or larger than the specified dimensions, may not meet the functional and safety requirements set by the NEC, leading to potential issues in maintenance operations. Adhering to the requirement ensures that access points serve their intended purpose efficiently and safely.
