But do you know how to size wire based on whether it serves a continuous load or not? How much wire can you put in a pipe? Can you bend pipe so that it is located exactly where it is needed without sawing it to pieces and using a bunch of couplings; i.e.....wasting material? How deep do you bury pipe under a roadway.......a sidewalk.......a flowerbed? How do you avoid derating every circuit in a pipe? How often do you have to support armored cable? How many circuits can share a neutral? What is the smallest wire you can use for an equipment ground? How do you overcome harmonics? Why do you have to use 90 degree C rated wire at the 75 degree C rating? There are similar bodies of knowledge for plumbers, carpenters, boilermakers, elevator techs, pipefitters, millwrights, sheetrockers yadda yadda yadda Having a hammer doesn't make one a carpenter any more than having funbags makes one a mother, n'est'pas? xponent And Just A Journeyman Maru rob _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
