One power plan, the switching, and the commissioning check
With every run measured and mounted, size the supply: published watts per foot times each run's installed footage, totaled, plus at least 20 percent current headroom, verified against the rated output of the driver you pick. Every part of this build shares one supply voltage: a 24V tape is fed by a 24V driver and switched through a 24V control, with no mixing. Every run returns in parallel on its own pair; series wiring splits the voltage and leaves the far cabinet dim.
Stop here and kill the breaker before any wire is joined, then confirm the circuit is dead. Everything on the line voltage side of the driver is work for a licensed electrician, following local electrical code, the NEC where applicable, and the manufacturer instructions supplied with the equipment: a hardwired driver, any junction box behind the joinery, in-wall cable, and the switch or dimmer box at the wall. Nobody probes or tests a live line voltage connection. Whatever this guide says about 24V, it hands nobody standing to take on that work unqualified.
Commission with the doors open and the room lights off, before any trim goes back on. Stand where you normally stand, then crouch to the lowest shelf. Check the back corners, check no emitter shows with the door at its widest, and check the pantry stile runs and the wall cabinet runs match each other for color. Room level questions sit in our pantry lighting guide and the in-cabinet lighting piece; if a run needs re-specifying, ask our team about your cabinet interiors.
Frequently asked questions
Where should the strip go in a deep pantry? Vertically on both front stiles, firing inward, so light reaches every shelf rather than only the top one.
Can I mount strip on an adjustable shelf? Better to light from the carcass. If you must, pin a service loop so the cable is never under tension.
Does a cabinet interior need a channel? Never mandatory. A channel helps dissipate the heat the strip generates, and it reduces but does not guarantee the disappearance of visible dots, which also turns on LED density, channel depth and diffuser type.
Will a door switch work with any strip? No. Confirm on the product page that the exact switch or controller supports door triggering with your strip and driver.
Should each cabinet have its own driver? Usually not. One driver can carry several runs if the combined load plus at least 20 percent headroom sits inside its rated output.
A pantry and cabinet interior lighting build passes or fails on one thing: the door opens, the shelf reads, and the strip never shows.
