Final answer:
Flexible connectors, such as ropes or cables, are used to aid in wire pulls in electrical systems. They are designed to have high breakage strength and minimal stretch. Common diameters for these connectors include 1/2 inch, 9/16 inch, 5/8 inch, and 7/8 inch.
Step-by-step explanation:
Wire pulls in electrical systems are aided by flexible connectors, called ropes or cables, which exert a pull parallel to their length known as tension.
These connectors are designed to have high breakage strength and minimal stretch, making them suitable for wire pulls.
They often have a factory-spliced pulling eye at each end to facilitate the pulling process.
Common diameters for these connectors include 1/2 inch, 9/16 inch, 5/8 inch, and 7/8 inch.
