What is the maximum length of a portable flexible cable jumper provided for connecting terminals?

The maximum length of a portable flexible cable jumper provided for connecting terminals is 75 feet. This standard length is established to ensure safety and effectiveness in electrical systems. Longer lengths can lead to issues such as voltage drop, increased resistive losses, and difficulties in handling and stability. By limiting the cable length, it maintains manageable electrical characteristics and helps reduce risks associated with longer cable runs, like overheating or electrical interference.

Understanding this guideline is important in practical applications, particularly in scenarios where portable connection solutions are necessary, as they must adhere to safety and performance standards. Keeping the jumper within this specified length range ensures both compliance with regulations and the reliable operation of the connected equipment.
