How to Wire a Kitchen Cabinet Light Fixture
Electrical Question: I have wall cabinets in the kitchen up to the ceiling.
- I have Romex coming into the back of the over-the-sink kitchen cabinet for a switched light fixture to be mounted under that cabinet for the sink area below.
- What kind of junction box should I use inside the cabinet to make the wiring connection to the wiring from the light fixture?

How to Install Electrical Wiring for Kitchen Cabinet Light Fixtures
- The electrical wiring inside the cabinet should be protected by installing it into flex conduit.
- The flex conduit can be run to a metal junction box such as a handy box, or single gang box.
- The box can be mounted above the fixture and a metal nipple can be installed between the fixture and the metal junction box.
- Depending on the type of light fixture, if there is a built in junction box which will contain the wiring connections then the flex conduit could be run directly to the light fixture location and a 90 degree flex connector can be installed to make the connection to the light fixture wiring area.
- Additional nipples or fittings may be added as required.
- Place a blank cover over the box after the wiring connections are made.

Can I have a junction box on the inside of a kitchen sink cabinet that only services outlets in the island? If so, does it need to be a junction box approved for wet or damp locations? And do the wires coming in and out need to be in Romex? Thanks very much.
Hi Thomas,
A junction box may be located inside the kitchen cabinet where it will be accessible and the junction box is not required to be water proof because this cabinet is typically a dry location. With projects like this a deep 4-square metal junction box may be installed and a connecting EMT conduit which is used to carefully penetrate the cabinet and the flooring to provide protection for a Romex or Type NM cable as you have described if this type wiring is approved and used in this location. Keep in mind that kitchen island receptacles are required to be GFCI protected and typically they may be part of the counter top receptacle circuits. Sharing the island outlet circuit power with the garbage disposal circuit is not recommended and is not acceptable by code.
