Peter your thoughts need to be relooked at, to consider the fact that it is new construction and nothing is live, is far from the truth (its gotta get powered up sometime for you to get paid or your boss!! secondly if you are willing to only front out $10.00 on a tester to chance your life you need to go get your head checked!! And as far as the vice thing i have seen many of plumber trucks with vices on the rear bumbers and i have used them my self. I have seen many comments on this web site , for the most part all are great, And there are always a few that make you just laugh and say what the Hel* is this person talking about. And no offence to you, but that was for sure one of the dumbest replies i have ever seen on this site. As for the new girl best of luck, buy things as they are needed, a good mech. will help you in picking what to buy! Welcome to the the sparky world.
