With SPT wire, you'll need one extension cord per element connected to an AC controller (like a CTB16PC or LOR1600). View the video in the item pages to see how to make custom cords. SPT wire can NOT be used as pixel extensions, or to provide power to your controllers. 

You MUST use the same SPT 1 or SPT 2 plugs as the wire you purchased - they are not interchangeable. The maximum amperages for both wires are 10 amps from 0-50 feet, 7 amps from 51-150 feet, and 5 amps for any length beyond 150 feet.

SPT 1 wire can withstand most weather conditions. If you are located in extremely cold or hot climates (like Alaska or near the equator), or are doing a permanent install you should consider SPT 2. 

Cat5e cables connect controllers in a daisy chain per network; you'll need one Cat5 cable per controller.
