Adding under-cabinet lighting? Plan the gaps and power source first

Decide whether a visible plug and cord are acceptable

Kichler's cabinet-lighting guide identifies plug-in systems as an option that uses an existing outlet, while noting visible cords and the loss of an otherwise available receptacle. Show which outlets you use for countertop appliances and where you would accept a visible cord. An outlet being nearby does not establish that it is suitable for the proposed installation.

A hardwired arrangement needs an electrical connection assessed by a qualified electrician. Ask for that work to be identified separately from fitting the lights. Do not assume a plug-in kit can be converted simply by removing its plug. The exact product's instructions determine its permitted supply arrangements.

Map the interruptions, not just the total length

On a sketch or wide photo, label the cabinet stretches A, B and C. Add accessible measurements without moving appliances or dismantling cabinets. A total such as “twelve feet” hides the gaps that the installation must address.

Armacost's connector guide distinguishes connections used between tape sections from those used to cross gaps or turn corners. Treat that as a reason to have the route designed for the selected system, rather than buying a generic connector assortment.

• Mark the length of each cabinet stretch and every corner.
• Show the sink, range hood, microwave and any break between cabinets.
• Photograph the cabinet underside, including projecting edges or dividers.
• Label the counter areas you want illuminated and any places where visible lighting hardware would bother you.

Check the whole system before buying extra sections

For a system using a separate LED driver—the power supply—Armacost identifies voltage, power demand and dimming method as selection factors. More tape is not automatically supported by the driver supplied with a starter kit. Have the proposed lengths and distance from the power supply checked against the exact products' limits.

Include model numbers for the tape or bars, driver, connecting accessories and proposed control. Armacost offers different connector arrangements for different lighting types; a matching brand name alone is not a complete parts check. State whether you want a wall switch, a local control or remote operation, and whether separate cabinet areas should operate together.

Agree where the equipment and finished work will go

Ask where the driver will sit and how it can be reached later. Armacost's driver guidance calls for installation conditions and ventilation to follow the selected product's requirements. Include storage use and access in that discussion rather than treating the driver as something to hide anywhere.

Before accepting the scope, confirm the visible cord route, any proposed cabinet openings, removal of old lights and any finish repairs. Send Coast & Craft the marked layout and product links together. Electrical suitability and the accepted work need review before a requested visit becomes an agreed appointment.
