We were doing some industrial work (www.atcoflex.com) in an old building and i found an old panel hidden away behind some boxes, the tag said "Trumble Electric Manufacturing Co." and the breakers had a T with a circle around it...anyways has anyone heard of this company? any info on it? btw, this panel was UL listed, it has the red ul sticker on it.
We have quite a few Trumble fused disoconnects in many of our Browning EOT cranes at my mill. I think they were installed around the forties or fifties, long before I was there.
I have seen and worked with Trumble breakers before. I believe that they are now obsolete and you might be able to get T&B breakers that are UL listed for replacements.
