NewInspector Posted March 9, 2007 Report Share Posted March 9, 2007 I am aware of the issues over old FP Panels, but have read reports of faulty or recalled Zinsco panels, Wadsworth & Push-matic breakers. Any info. on any (except FP) is appreciated. I'd also ask NE Inspector's if they'd ever come across Zinsco panels. It seems these are geographically limited to W & SW US. Thank you in advance for taking the time to reply. Link to comment Share on other sites More sharing options...
kurt Posted March 9, 2007 Report Share Posted March 9, 2007 Fair amount of Zinsco's in Chicago; problem is how the breakers attach (or don't attach) to the crappy aluminum bars. Wadworth are kinda cheesey, but I've seen hundreds, maybe >1000, and haven't ever seen any problems. The breaker connection to the bar seems adequate, unlike FP. Pushmatics are some of my favorite; I've "owned" a couple of them, and have seen hundreds of them. The breaker secures to the bar w/a screw. For reasons I've never understood, folks talk them down because they're old. I think they're excellent. Only problem is breakers are 2-3 times more expensive than new/conventional.

Mike's looked, I've looked. . . it just ain't out there. I rarely see Wadsworth equipment, but it seems decent enough. Its biggest problem is age. The Wadsworth panels I see are about 50 year old. Like Kurt, I think Pushmatic panels are great. They make me wonder why modern manufacturers gave up on the concept of bolted-on breakers in residential panels. If you ever run into any, the really, really old Square D panels are a disaster. I haven't seen one of those in many years though. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...
PAbernathy Posted March 10, 2007 Report Share Posted March 10, 2007 Yeah...basically in the 60's around the time the first series of AL wiring started to come out the makers of Zinsco swutched from CU buss to AL busses and they were awful in regards to pitting and causing arc's and overheating. They do make a copper retro-kit for the zinsco but you have to wonder....why even bother....Now the breakers ironically did not have a real problem with tripping....it was more to deal with the poor condition of the AL buss bars themselves. I have also seen my fair share of pushmatics and to be honest with you the biggest issue was replacement cost and limited capacity so really I don't have any research on their problem issues and I have not really witnessed any...that are more so glaring than the issues I find daily with Cutler Hammer, Square D and GE........breakers over time simply wear out with age and with age comes loose connections to the buss and possibly arc and heat issues.....age ends up getting us all in the end.

Les Posted March 10, 2007 Report Share Posted March 10, 2007 Same as all of the above. Zinsco was the preferred breaker for thousands of pre-cut and modular houses. Marketed by the old Wickes Lumber co, Miles homes, and many houses built under the FHA 230's program. My additional concern with Zinsco, not as scientific, was physical configuration and sizes made them difficult to keep aligned. Pushmatic from Bulldog Electric are great breakers, just costly. not a favorite of skilled homeowners, as they require a little effort to install and they look scary! Sometimes difficult to "see" if they are tripped. Recently "beat up" on an inspector that learned from a national school that Wadsworth panel were defective. Court ruled that inspector should have researched and had actual knowledge before writing it as defective. He paid - school got off hook! A layperson could confuse Wadsworth with FedPac if no labels were present and that was what the "inspector" was - a lay person! Good question - now you know.

Neal Lewis Posted March 10, 2007 Report Share Posted March 10, 2007 New Guy, There are still some Zinsco panels left in the NorthEast. Les, every Wadsworth I've seen has brown breakers with the sliding handle; might there be another style of Wadsworth to be confused with FP?

kurt Posted March 10, 2007 Report Share Posted March 10, 2007 There's big bunches of Wadsworth panels in Chicago apts. that look like FP's; they're usually little 6-12 circuit grey units. Link to comment Share on other sites More sharing options...

Brian G Posted March 11, 2007 Report Share Posted March 11, 2007 There was a wholesale electrical supply in my town who dealt Zinzco for decades. Lots of 'em still around, not getting any better. When I sold electrical stuff I used to see a few dozen Zinzco breakers per year with dime-sized holes burned in the sides or fried-black bus bar clips. I wish I had kept them now. Les mentioned alignment problems. Those long, straight bus bars they used meant there were no "designated spaces" for the breakers. You could plug one on and slide it up or down if you wanted to, which they sometimes do on their own if the twist-outs in the cover are missing below the breakers. Brian G.

hausdok Posted March 11, 2007 Report Share Posted March 11, 2007 Hi, Lots of Zinscos out here in Seattle land. Got one in the back of my car right now that's got a fried bus. I use it for demonstration purposes. For about 10 years it was pretty hard to get breakers for them. Then Thomas & Betts bought the tooling rights and the Zinsco name around 2000 and began making the breakers again. Now the prices are way down and they're pretty plentiful again. Still crap, but as long as they keep making parts for them people will continue to keep them. OT - OF!!! M. Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted March 25, 2007 Report Share Posted March 25, 2007 Okay ... what about a Magnetrip panel? Is it just another name for a Zinsco? I ran across one today in a very small closet in a Master Bedroom in a home built in 1958. 60-amp main breaker cutoff. All copper. No obvious damage, etc. under deadfront.

hausdok Posted March 25, 2007 Report Share Posted March 25, 2007 Hi, Yep, a Magnatrip is a Zinsco. See the photo below. It's a Magnatrip a client had yanked. I sent it to Douglas Hansen and he rewired it to use as a training aid. I carry around the guts of a Magnatrip in my truck, just to show folks the arcing on the bus bars behind those breakers. They're old, over 40 years. Most electricians and educators that I've asked, agree that electrical components have a service life of about 40 years. Besides its age, there's no bending room in the danged things and once you've got it fully wired you have to fight with the cover to get it on because the box will be so full. Besides, there's hardly enough room for an adequate number of breakers for a small apartment, let alone a house. MOFWIW ONE TEAM - ONE FIGHT!!!

PAbernathy Posted March 25, 2007 Report Share Posted March 25, 2007 Yep...here is a picture of the side of one of those breakers.. Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted March 25, 2007 Report Share Posted March 25, 2007 Mike & Paul, Tnx much. I've already keyed in that a qualified, licensed electrician needs to review. The panel I saw today looks like your image (Mike) ... save for the new wiring. Link to comment Share on other sites More sharing options...
