What is the maximum length allowed for a power supply cord connecting information technology equipment to a branch circuit?

The maximum length allowed for a power supply cord connecting information technology equipment to a branch circuit is 15 feet. This specification is outlined in various electrical codes and standards, including the National Electrical Code (NEC) and guidelines from recognized standards organizations. The 15-foot limit is set to reduce the risk of potential hazards associated with long extension cords, such as overheating or tripping hazards, while also ensuring that devices receive adequate power without a drop in voltage.

While longer cords may be available in some contexts, the 15-foot limitation is established to promote safety and compliance with regulations that protect both users and equipment. This length strikes a balance between accessibility and operational efficiency, allowing for flexibility in device placement without compromising electrical safety.
