Ben H Posted February 13, 2010 Report Share Posted February 13, 2010 1: Had a home this morning that has what I believe is nickle/copper clad branch wire on a few circuits. The reason I think this is 1) built in 1941 2)Cloth(ish) jacket on the wire. I was hoping someone could clarify what style jacket was used on Aluminum wiring? I was thinking it was never that braided cloth like stuff? No? 2: What do you guys do when you're uncertain about "that silver looking wire in the panel"...I have not made a call about the wire/breaker size due to the fact I'm not 100% sure of what metal I'm looking at[:-bigeyes Link to comment Share on other sites More sharing options...
Robert Jones Posted February 13, 2010 Report Share Posted February 13, 2010 Hey Ben, Do you have a pic? Is it a grey/silver jacket? Could possibly be NM. Link to comment Share on other sites More sharing options...
msteger Posted February 13, 2010 Report Share Posted February 13, 2010 All of the solid conductor AL Romex wiring I've seen had a plastic outer sheathing like like modern copper Romex. You would see "AL" printed on the jacket. Base upon what you describe, I don't think it's Aluminum wiring. Link to comment Share on other sites More sharing options...
plummen Posted February 13, 2010 Report Share Posted February 13, 2010 is it knob/tube wiring? Link to comment Share on other sites More sharing options...
Neal Lewis Posted February 13, 2010 Report Share Posted February 13, 2010 If the house was built in 1941 with a cloth jacket, it's not aluminum. The date range that aluminum was used for branch circuits is not even close to 1941. Link to comment Share on other sites More sharing options...
Ben H Posted February 13, 2010 Author Report Share Posted February 13, 2010 It's not K&T. The house had a 3 wire service, 100-amp panel. All but three breakers had copper wire. I'm leaning heavly toward clad... if you look closely you can see a nick in the bottom wire that shows a tiny bit of copper shinning through. But the other two do not. Do the same rules apply to clad, 14g to 15amp / 12g 20amp ? If so looks to me I've got 14g wire on 20 amp breakers. Click to Enlarge 48.68 KB.
