A conductor should never be payed out from which type of reel?

The choice of a non-rotating reel as the type from which a conductor should never be paid out is based on the functionality and design of such reels. Non-rotating reels are typically fixed in place and do not allow for the natural unwinding and management of the conductor as it is being paid out. This can lead to issues like tangling, excessive wear, or damage to the conductor, as it does not provide the necessary freedom of movement during use.

In contrast, rotating reels are designed to allow conductors to be unwound smoothly and safely while enabling the reel to turn, thereby preventing twists and kinks. Standard and manual reels often incorporate features that facilitate easy and controlled unwinding of conductors. Thus, using a non-rotating reel can significantly increase the risk of operational hazards and equipment damage, making it unsuitable for such tasks.
