3 wires and a # 6 wire from a run from my house to a 100 amp sub panel in a detached garage. It will be 2 inch PVC conduit. The run will start in my attached garage where the main panel is located. It will go inside that wall up about 10 feet into an attic space above my garage. It will run about 20 feet across the attic and then go outside into an LB fitting. It will go down to the ground on the outside of the attached garage for about 15 feet into a sweeping 90 then a straight run of 50 or so feet to my detached garage. The total run is about 110 feet. I will be mostly working by myself maybe the wife could help.
Anyway, is it best to start in the attic, run the wire down into the main panel then out through the outside wall. Will it be a pain to unravel this wire in the small attic?
Or would it be best to start at the detached garage, run it through the long straight run, then up the attached garage wall into the attic ect.
I will have LB?s above the main panel, Outside the top of the garage, and inside the detached garage just below the sub panel.
Any advice is appreciated! I have a small tractor if that helps but I am hoping I can do this by hand.
I can't advise you about all the pulls around the 90s and stuff, but I will offer one thing about laying out the wire. When wire is coiled, particularly stiff wire, unless it is rolled directly off a spool, it comes off in a spiral. In order to keep it from spiraling, it has to be laid out in a straight line, then taken in 2' diameter loops, one over, one under, nontypical of the usual way you roll up a garden hose in your hand. When the stuff comes off the roll, it will not kink all up on you in the attic after the second or third loop, making a big tangle.
This is used particularly for wire rope, but works well for garden hose, electrical cable, and anything you want to keep from spiraling. It takes a few minutes to learn and master, but once you learn it, it's impressive when you can toss out a big roll of something, and pull it all out without any spiralling, while your observers scratch their heads. It keeps all manner of stuff from kinking, good garden hose being the most common.
I watched a team of divers at a dock one time try to take down some wire rope. They had the spool laying on its side. They took off a little, and the diver started down. As he went down, they just rolled loop after loop upwards off the side of the roll. Within a few loops, they had such a tangle they had to pull up the diver with the wire rope and hose and all tangled into one big mess.
I just kept on walking, chuckling to myself. Wire rope can be a pure d bitch if you don't know a couple of tricks.
So, if you're using rolls, take it straight off the roll. If you are buying precut lengths, lay it out, and do the one up one down laying of it in your opposite hand, and it will come off straight. Just be sure that you don't take the end of the loop through the center of the roll at the start, or you will end up with a series of overhand knots.
I really need to learn how to post this stuff to youtube, as I have a great video camera, and could do this easily.
