Pulling electrical cable through conduit requires a systematic approach to ensure safety and prevent costly damage. Our recommended professional process is as follows:

1. Plan the Pull: Before you start, measure the conduit length and identify all bends. Calculate the total bend angle, which should not exceed 360 degrees between pull points (as per international standards). This planning step is crucial to avoid excessive friction and over-tensioning.

2. Inspect and Clear the Conduit: Use a conduit brush or a "conduit mouse" with a vacuum to clear any debris, such as dirt, water, or small stones, that could snag the cable or cause friction.

3. Feed the Pulling Line: For long or complex runs, use a fish tape, pulling line, or conduit rods to thread a line through the conduit from one end to the other. A vacuum is a highly efficient method for sending a line through the pipe.

4. Lubricate the Cable: Apply a generous amount of wire-pulling lubricant to the cable as it enters the conduit. This is the single most effective way to reduce friction and minimize pulling tension.

5. Connect the Cable: Securely attach the cable to the pulling line using a suitable attachment, such as a wire mesh grip or a specialized pulling eye. Always include a pulling Swivel to prevent the cable from twisting during the pull.

6. Pull the Cable: Use a manual or motorized winch to begin the pull. A motorized puller with a built-in tensiometer is the safest and most efficient option, as it provides a constant, controlled force and allows you to monitor the tension in real-time.
