Is it permissible to have architectural appurtenances in the working space of electrical equipment?

The presence of architectural appurtenances in the working space of electrical equipment is generally not permissible because it can create safety hazards and impede access for maintenance and emergency services. The working space around electrical equipment is designated to ensure that technicians and personnel can safely operate, inspect, and maintain the equipment without obstacles that could lead to accidents or injuries.

By keeping this space clear of any obstructions, it allows for proper airflow, minimizes potential fire hazards, and ensures that emergency responders can quickly and efficiently access the equipment if needed. This standard is crucial for maintaining a safe working environment, particularly in locations where electrical control panels and other potentially dangerous equipment are present.

The other choices suggest varying degrees of permissibility for including appurtenances, which can compromise the integrity of the working space. The focus on maintaining a clear and accessible area reflects industry best practices and safety regulations.
