I got 200' of 14AWG wire and none 16AWG left. I was thinking about using it for all rocker switches. Including lights, bait well and manual bilge pump switch. The wires that come out of the pumps are 16AWGWhat are you powering? If it's just lights, gauges, and stuff, you should be fine. If is's a bait well and/or bilge pump, check the item to see what gauge wires come out of it and don't go lower.
