Wiring methods and equipment installed behind suspended-ceiling panels shall be arranged to allow access to the electrical equipment.

The statement is true because electrical codes and standards require that wiring methods and equipment be installed in such a way that they can be accessed for maintenance and inspection. When electrical equipment is hidden behind suspended ceiling panels, it is essential to ensure that there is a means for accessing that equipment safely and effectively. This access is critical not only for routine maintenance but also for emergency situations where timely access to electrical systems may be required to manage faults or hazards.

The design of a building's electrical systems considers future serviceability, safety, and compliance with applicable electrical codes. By ensuring that equipment can be accessed as needed, it helps to prevent potential issues caused by inaccessible wiring, such as damage or malfunction that could go unnoticed. This practice also aligns with safety standards designed to protect both the facility's occupants and maintenance personnel, reinforcing the necessity for proper installation and accessibility of electrical systems behind ceilings.
