The maximum extension allowed for electrical equipment within a working space is 6 inches. This regulation is in place to ensure safety and accessibility, preventing obstructions that could hinder maintenance or emergency access. When working with electrical installations, it is essential to maintain a clear working area, as this reduces risks related to accidents, allows for easier inspections, and ensures that personnel can operate safely.

In many electrical standards and codes, including those observed by the NYC Department of Buildings, maintaining this specified distance helps facilitate effective workflow in environments where electrical equipment is prevalent. Keeping extensions to just 6 inches ensures that equipment does not protrude excessively into the designated working area, allowing for safe and efficient operation.
