- Clear the hole of debris. Use a vacuum cleaner or compressed air to remove any dust or debris from the hole.
Determine the Length of Cable Needed
To determine the length of cable you need, follow these steps:
1. Measure the Distance
Using a measuring tape, determine the distance from the source of the cable (e.g., the electrical panel) to the destination (e.g., the outlet). Measure along the path where you plan to fish the cable, taking into account any obstacles or detours.
2. Account for Slack
Add additional length to the measured distance to account for slack. This is important to prevent the cable from being taut, which can put stress on the connections and increase the risk of damage.
3. Consider Future Needs
If you anticipate adding additional cables or devices in the future, consider getting a longer cable to accommodate those needs.
4. Calculate and Round Up
Add the distance you measured, the slack you added, and any future needs. Round the result up to the nearest standard cable length. For example, if you need 25 feet of cable, round up to 30 feet.
| Cable Type | Standard Lengths |
|---|---|
| Coaxial | 10, 25, 50, 100, 150, 200 feet |
| Network (Ethernet) | 10, 25, 50, 100, 200, 300 feet |
| Electrical | 10, 25, 50, 100, 150, 200 feet |
Pull the Cable Through the Pilot Hole
5. Pull the cable through the pilot hole using a fish tape or cable puller:
