I am installing some L.V. puck lights on the bottom of some overhead kitchen cabinets. The receptacles for the plug-in xfmr's are located in the top interior of the cabinet. After looking at article 411 I realize I can not run the puck light leads into the wall cavity at the top of the cabinet and back out under the cabinet per 411.4. My question is how do you guy's hide this wiring mess and still meet NEC requirements?
