Rewiring a Basement for Additional Light Fixtures
How to Install Basement Electrical Wiring: Basement Wiring Methods for Switches and light Fixtures, Code Compliance, Top Down Wiring Method.
Wiring Switches and Light Fixtures in a Basement
- Does every switch go to a junction box in the ceiling and then to the main junction box for power.
- Or with the one main junction box break the feed lines coming out with just a switch then the light and back to the junction box?
- This is the hex box in the ceiling that goes to a main switch and circuit breaker box.
Thanks for any help.

Thanks for your electrical wiring question Allan.
How to Install Basement Electrical Wiring
- Skill Level: Intermediate to Advanced.
- Tools Required: Electricians Pouch of Hand Tools for Rough-In Wiring, Electric Drill and Auger Bits, Extension Cords, and a Ladder as needed.
- Estimated Time: Depends on the extent of the basement wiring project and available access to the project area.
- Precaution: Any existing wiring in the immediate area that may interfere with the new wiring should be identified, turned OFF and Tagged.
- Notice: Installing additional electrical wiring in the basement should always be done according to local and national electrical codes with a permit and be inspected.
Basement Wiring Methods for Switches and light Fixtures
- Observe the Existing Wiring Methods
- The wiring method is up to you as long as it is compliant with your local electrical codes.
- Code Compliance
- Electric Codes now require a neutral wire in light switch boxes.
- It also depends on the type of construction materials or structure, obstacles etc. that are found in the basement area.
- Common Methods for Basement Wiring
- I personally like to bring the power to the switch box and then take the wiring to the fixtures and loop them. I keep the number of junction boxes down to a minimum.
- If the wiring is planned out correctly then there will not be any junction boxes at all, only wall switch boxes and fixture boxes.
- Top Down Wiring Method
- The Top down wiring method is where the circuit power is installed into the ceiling fixture boxes first.
- Next the switch wiring is installed from the fixture box down to the wall switch box.
- The circuit power loops from fixture box to fixture box.
- NOTE: Circuit power must be installed into an approved junction box.
- Smaller wiring boxes that are built into light fixtures may not be designed or large enough to serve as the circuit power junction box.
- Junction boxes must be installed in an accessible location.
