How far from termination points may horizontal runs of EMT be fastened?

Horizontal runs of EMT (Electrical Metallic Tubing) must be fastened to maintain structural integrity and safety, preventing sagging or misalignment. According to electrical codes, the proper fastening distance for EMT runs is crucial to ensure that they are securely held in place.

The correct fastening distance from termination points for horizontal runs of EMT is 900 mm. This distance allows for adequate support along the length of the tubing, ensuring that it remains stable and secure, particularly in environments where vibrations or movement may occur. Fastening at this interval helps to prevent potential strain on connections, thereby enhancing safety and compliance with the relevant codes.

Distances shorter than this may not provide sufficient support, while longer distances could lead to an increased risk of the tubing becoming loose or damaged. Proper adherence to these fastening requirements is essential for maintaining the performance and safety of fire alarm systems and other electrical installations.
