I went to pull wire for the circuits in the front of my boat today. Didn't go as smoothly as I'd've liked since I used 1/2 PVC for my wireways (bigges I could fit through the space I had) and I had to pull through a couple of 90 degree fittings. My fishtape wouldn't go through, so after scratching my head a while I raided my wife's knitting bag and stole about 20' of her yarn. I tied a bit mess of knots in the end and put the shop vac on the other end of my wire run. Pic is of the end of the yarn after sucking it through the pipe with the vacuum. Following images are of the other steps to pull 4 hots and 3 grounds through. 14 gauge wire since all I'm planning up front is lights. I have another wireway under the deck for additional pulls if I need them.
