Circuit Breaker manufacture dates

M Gilmore
Hi, I am currently working on a project and I require the manufacture dates of various circuit breakers. I have contacted Schneider (Square D), Eaton (MEM, Memshild etc) and Electrium (Crabtree, Volex, Siemens and Wylex) Schneider have come back but that's it. Does anyone have any old catalogues that are dated? Have any data sheets or have any other evidence of such dates? I'm after information on all types of circuit breakers, so Federal Electric and Dorman Smith included!


Thanks in advance, hopefully someone out there can help me in my quest.

    Andy,

    Apologies, I did not mean to put words in your mouth, I just wanted to make sure nobody read it that way. I have had many occasions where I had to look at modifications to an old installation with limited information on the installed equipment and had to make use of old catalogues to reverse engineer the system design. This is unlikely on a domestic installation but can happen on an industrial one - one recent installation I looked at had a switchboard dating from the 1990s, and that was the new one. The old ones were from the 1960s. Needless to say the design information available would fit on a post-it note (with room to spare)..
