When drilling a hole for electrical wiring, it is important to make sure the size of the hole is appropriate. Here are some guidelines:
- Drill a 1/2 inch hole for one or two 14-gauge wires and a 3/4 inch hole for two 12-gauge wires.
- When running more than two wires through a single stud wall, use an old work box that fits in the wall space you need to fill.
- If your project requires more than one wire, consider using conduit instead of fishing individual cables between walls and floors.
In all cases, be sure to follow local codes and regulations.
