The neutral and the ground in the main box in my house were put on a common bar. The bond screw to the box housing is in place and it appears the box has holes for a ground bar to attach, this just seemed to be an easier? solution to whoever originally wired it. This setup passed inspection at the time (1984). There appear to be enough spaces on the bar for everything going to it (however some of the neutrals are double-tapped anyway:confused: -- looking at the circuits they appear to be part of the house originals too). Is there any reason to add a proper ground bar to the box at this point and pull all the grounds over to it, other than just making the inside of the box less spaghetti like? This is complicated by the fact that the box was made by Sylvania, whom I understand quit making boxes and would make finding the proper ground bar difficult, if not impossible.

Were are in the process of installing a new duel fuel range. The information the the stove states that it has a 3.6KW / 240 rating and that 20amp 12 guage wire is okay. To be safe I ran 10/3 and was going to put it on a 30 amp 240 breaker. I was told that even though this maybe true, code requires that 8/3 needs to be run for ranges regardless if the stove draws that high of amps. Is this true? Idaho follow NEC. Thanks, Clay
