How to Install Kitchen Cabinet Lighting

Updated July 20, 2017

Lighting in the kitchen is essential. Many homeowners have turned to under-cabinet lighting to achieve a decorative and utilitarian aspect in their kitchens. Today's under-cabinet lighting opens the door to a perfectly coordinated kitchen. The installation of under-cabinet lighting in the kitchen is a moderately easy and straightforward process. The result is a kitchen with task lighting exactly where it is needed and a decorative flair that helps convey your personal design tastes.

Locate the electrical breaker that feeds the electrical line. Turn the breaker to the "Off" position.

Remove the glass light covering.

Remove the included wiring cap nuts from the light's wiring.

Place the lighting fixture up against the underside of the wall cabinet. Use a pencil to mark on the cabinet where the screws will need to be installed. Mark the narrow part of the screw keyhole.

Use a drill or screwdriver to secure the supplied screws in the marked spot on the underside of the cabinet. Leave 1/2 inch of the supplied screw exposed from the upper cabinet.

Use the back of the screwdriver to remove the plate in the power supply housing of the fixture. Insert a Romex connector into the hole.

Use the supplied terminal screws to secure the housing near the electrical supply hole.

Insert the electrical wire though the electrical supply hole and Romex connector.

Match and secure the wiring to the light fixture. Use wire connectors, and connect the black wires to each other. Connect the white wires to each other. Connect the ground copper wires to each other. Make sure that each connection is secure and complete with a wire connector.

Place the light's housing unit keyholes over the exposed screws. Slide the unit until the screws are covered by the narrow keyholes. Use a screwdriver to further tighten the screws, if necessary.

Use the supplied cap nuts to secure the wiring compartment of the light to the rest of the lighting fixture.

Install appropriate and manufacturer-recommended light bulbs.

Replace the glass lighting covering on the light housing.

Turn the electrical breaker to the "On" position.

Check that the light is working by using the operation switch on the light fixture.


Working with electricity should be done with caution. If you feel that these instructions are beyond your personal scope, employ a professional to complete the electrical work for you.
