It comes with enough wire to do two 10 ft runs for my system. I have it running through the a attic in my garage and was concerned about built up static electricity. It comes with a drill bit and connecting caps. I touch up the holes with caulk so it doesn't loose any of the suction.
I thought I could go to a home center and get some uninsulated wire cheaper but could not. I wadded up a piece of paper and taped the wire to it and turned on the dust collector and let the suction the wire through. Quick and easy. Three stars because I already have drill bits, screws and wire nuts.
