How to Add Electrical Wiring for a Outlet and Light Switch
Electrical Question: How can I put a junction box into the circuit wiring before a light fixture so I can add an outlet light and switch.
- I would like to continue an electrical circuit by adding another outlet and a light switch and light, and I have run into a problem.
- The only access to the end of a circuit I can tap into is from a 3way light fixture.
- The existing 3-way switch has the power coming into it and then to the light and then to the second switch.
- My question is, is there a option of how to put a junction box on the wire before it hits the light because I would like to have continuous power to future outlet and light and switch.
- I don’t want the new branch to be controlled by the 2 existing switches.

Extending Electrical Circuit Wiring for an Outlet and Light Switch
Common Problem when Installing Circuit Wiring from a Light Switch
- Extending Electrical Circuit Wiring
Jake, you cannot extend the wiring form the light fixture that is controlled by the two three way switches unless the switch box is the location of the power source.
- Adding onto an Electrical Circuit
To add circuit wiring for another light switch or outlet a power source must be located which contains a circuit power source which includes the white neutral wire, the black power wire and the ground wire.
- Locating a Power Source
With this question, it may be best to extend circuit power from another source, such as a wall outlet or a wall switch that has both a neutral and hot as needed for the continuous power source.
- Available Circuit Capacity
The circuit must have available capacity to provide additional power for the devices that will be added.
- Electric Circuit Cable Type
When extending an electrical circuit the cable type and size must be the same as the existing circuit wiring that will be spliced into.
