Just kinda curious.... Does anyone else consistently see this everytime they open a Zinsco panel?? Seems like everytime I walk up to one.... I gotta change it out because the bus & the breakers just didn't get along & arc-ed themselves unto uselessness!
Thats why they sell replacement buss bars for some of those POS panels,the only good use of a Zinsco/Sylvania panel is scrap metal. With the cheesy lugs on their twin breakers that must have been fun for whoever double lugged that 20A breaker in the top photo.
P.S. What is amazing is that there are installations from the 50's still in service.
This is original equiptment from a house built in 1972... Just in the past year I've ripped out at least 40-50 of these... also in that time, I think I replaced about 10 FPE, another 10 Bulldogs, maybe 4 or 5 Bryant/Westinghouse, a Square D "XO", a Trumbull, & a seriously prehistoric one that had an "E" with a diamond around it as the only legible marking left.
For some reason, Zinsco was a seriously popular brand out here in So California in Tract-Homes built anywheres from the 50's - into I think the early 80's..
I think Zinsco is the only brand I have ever seen that uses (or used) the "push and pray" style wire connections . I guess their rationale is ... why should poor connections be limited to wiring devices only...
My parents finished the basement in the place where we lived in the late 50s - early 60s. The original FPE inside was full so the electrician added a Zinsco beside the meter outside and the FPE became a sub. Now that I look back, it is a miricle the place survived
I find FPE panels here & there... I came across some tract houses in San Diego & Oceanside which had FPE panels AND aluminum wiring! (Talk about bad getting worse!), & they were from the early 80's... I think the EC that did the original build must've gotten them on clearance or something Another peculiar thing I found was a supply house in San Diego which STILL had FPE 100A meter/mains in the box! (You know a good product when it's still on the supply house shelf 20 years later!) Most of the FPE panels I get called to replace are the old 6 circuit/no main style from the 40's & 50's..
Another peculiarty with a specific manufacturer... I've come across 3 or 4 Cutler-Hammer "CH" style panels where the 100A main breaker actually caught fire! No damage occured outside of the panel can except for some blackend stucco, but it was strange & kinda eerie seeing that more than once, in different cities & build era's at that!
I come across FPE, Square D "XO"'s,Bulldog "Pushmatics", even Wadsworth & Trumbull boxes that are pushing 50-60 years old that are still in basic "working" order & get changed out mostly as an upgrade.... But the Zinsco changeouts are alomst always due to equiptment failure.. As I'm writing this, I just came back from replacing a Crouse-Hinds 100A main that refused to reset.. Albeit there was enough dirt in that panel to grow an orchard.... 5 minutes, a brush & some "Lectra-Clean" & the bus looked new again
