Power to moving door?

Building a bookcase door which will have LED strip lights on shelves. How can you run power to a door which opens and closes? What type of connection or harness would be safe and durable?

Powering the lights you will need a transformer (many times call a wall wart) that will change the 120 volt from the wall down to the voltage you need for your lights, likely 12 volts or less. The reason I was hopeing you were going low voltage is because you can pretty much wire it however you like using almost any type of cable/wire. You could even run it inside the frame of the door. Low voltage is just that safe. Of course the two wires/pieces of metal can't touch or the transformer will burn up.

If it doesn't have to be lit when open a set of contacts on the door jamb and on the hinge edge could be used. Heck, you could use one hinge for positive and one for negative. If the bookcase is wood and the jam wood there should be enough insulation.

I'd recommend 14ga SO wire (black rubber 2 or 3 wire cable). SO is flexible and intended to be moved. Even though it's low voltage, I'd still wire it "traditionally" so you don't have operational problems later down the road.
