What is the maximum pull on cables pulled through cable trays using a basket grip not attached to the conductor is?

The maximum pull on cables pulled through cable trays using a basket grip not attached to the conductor is typically governed by the manufacturer's specifications for the basket grip and the type of cable being used. Generally, the pulling tension should not exceed 25% of the cable's rated tensile strength or the limits set by the National Electrical Code (NEC). Additionally, factors such as the number of bends, the length of the run, and the weight of the cables should also be considered to ensure safe handling and installation. Always consult applicable codes and standards for specific guidelines.
