You guys have alot of interesting old things here and after spending a couple of hours looking through the threads I was thinking that you guys might apreciate my pieces. One is an old 250v 3000a 3-phase ITE main switch manufactured in 1924 (actually 5-13-1224, it still has the original tag with date and serial number on it). It is still in my van seeing that it weighs about 700 pounds and I have'nt figured out how to get it out yet. I have not been able to find anything like it anywhere on the net. The other thing I saved from the demo crew is and old 250v single phase Trumbull fuse board with knife switch disconnect and a pair of old 200a main fuses. I also saved a few old fuses(600a and 150a). The first two picyures are when it was in use before I shut it down. The closeup one is a thumbsrcew that slides something inside it under a copper label that the numbers go from 3000 to 4500. Any Ideas what that does? This is a great site and I'm glad I stumbled across it.
More stuff to come!

I'll take a wild guess.
It's an open air circuit breaker and the knob is for ampacity adjustment.

Very cool looking stuff.

I'll bet the sparks that thing throws out when the contacts open or close is impressive . I hope a really long operating stick goes along with it . I kinda wonder what they used for PPE back then?

Those big ol' live front switchboards are neat pieces of work!
