Connecticut Electric Zinsco replacement 2 pole 100 amp full size breaker
came in barely working order - had to "play" with both for at least 5 minutes and was thinking to send it back, due to the mulfunction, but than finaly got it to work (do not know how long it will last - used only one and the other was kept for spare) - paid express shipping as well to get it a.s.a.p. price was right, about 40% less than anywhere else, but - "you get what you paid for" - if i had to do it again - probably would not.

Nice positive click as soon as I flipped it let me know it was working great right out of the package. A quick continuity test and then loosening the screws and I know I could snap it in and it would solve the "only 110VAC flowing on one rail" problem. Popped right in and worked first time. I guess either I got lucky or the DOA problem was fixed in manufacturing.

Had not one, but two of these breakers arrive defective.
Amazon refunded my money right away.
Still lost 4 days with no power because of this junk. Home depot.com sells another brand that seems fine

We live in a house built in 1964. The help at big box retailers did not what it was, let alone carry it.

Product was defective. Only one side worked. When I emailed Connecticut Electric, they assured me all products were inspected and tested under camera supervision prior to being mailed to customers. They did refund me the purchase price, but further insulted me by writing their inspectors determined that the product had been used. Of course I had installed it, how else would I have know only one pole worked.

The first one I received only one pole worked. Amazon was great about getting me a second one.
I used this in an old GE panel from the 1970's and it fit on the bus bars, however I had to cut and modify the panel cover because it was deeper than the original breakers.

Used it to replace my neighbor's main breaker that kept tripping

Remember to use Noalox® Anti-oxidant Compound on ALL aluminum electrical connections that are exposed to humidity or rated 50 Amp and greater!

Amazon sent me a scuffed up "used" breaker not NEW as shown. Had to send it right back. I don't know if it works or not, didn't even bother testing it. Amazon quality & advertising is going down hill fast.
