What is the minimum depth requirement for a working space around electrical equipment?

The minimum depth requirement for a working space around electrical equipment is indeed 4 feet. This distance is essential to ensure that personnel have adequate space to safely perform maintenance and other work tasks on electrical systems. The working space needs to be clear of any obstructions, allowing for safe access to electrical equipment, which is crucial for minimizing the risk of accidents or injuries.

This requirement not only facilitates safe operation but also assists with effective circulation of air around equipment, which is important for cooling and equipment longevity. Maintaining this space helps ensure compliance with safety standards outlined in the National Electrical Code, promoting a safer working environment for electricians and maintenance personnel.
