MTL_Inspet_Man Posted March 30, 2010 Report Share Posted March 30, 2010 See a couple of pics from yesterdays inspection. Triplex, construction circa 1971, the main floor unit is wired using a combination of copper and aluminum wiring. i know it's ok to have both copper and aluminum inside the same box. However I am concerned on how the ground copper and aluminum wires have been weaved together. I am recommending further investigation and yes I know its a pushmatic panel. I am just wondering if the Alum and Copper wires should have been kept separate. Your help and insight is always greatly appreciated.

I'd be more concerned that a bunch of the equipment grounds don't terminate anywhere. There's no problem with having the aluminum equipment grounding wires touching the copper grounding wires in the panel. They shouldn't be terminated together under the same lug, but otherwise there's no problem with incidental contact. Each and every equipment ground should terminate under a lug. Get rid of the double tap at the left breaker third from the top. Nothing wrong with Pushmatic panels aside from their age. They were among the best ever made. How did the neutral terminal bar look? - Jim Katen, Oregon Link to comment Share on other sites More sharing options...
MTL_Inspet_Man Posted March 30, 2010 Author Report Share Posted March 30, 2010 The neutral bars looked good. and yes due to the grounds not all being properly terminated there were some open grounds on some outlets that are energized from this panel. Yes the double tap is written up. as for the pushmatics they do operate well i tripped a couple removing the panel cover...lol thx i am recommending further evaluation by an electrician. thx for the help Link to comment Share on other sites More sharing options...
