The correct height requirement for the entrance to a working space around electrical installations over 600V is indeed 6 feet. This standard is important for ensuring that electricians and other personnel have sufficient vertical clearance to safely access the working space without the risk of injury.

The National Electrical Code (NEC) specifies this minimum height to provide a safe working environment. A height of 6 feet is adequate for most individuals to perform tasks without having to crouch or bend excessively, thus reducing the risk of accidents or injuries. The provision of this specific height not only encourages compliance but also aligns with safety practices in electrical installations.

In contrast, choices that propose heights below or above this requirement would not meet the established safety and practical working conditions outlined in the NEC and may lead to insufficient access or increased risk while working near high-voltage installations. Therefore, knowing and adhering to the 6-foot height requirement is essential for anyone involved in electrical work under these conditions.
