I have one of these Frank Adam panels (a smaller one, fortunately - 20 circuits, 120-240 volt single phase) in my collection of vintage electrical equipment. It was given to me by a friend on the occasion of demolition of an old country club building. A couple of the fuse sockets were nearly incinerated from the intense heat of overfusing/overloading for many years. I remember doing sound jobs in this old building and having to replace a burned out fuse every once in a while. You could literally feel the heat radiating out of this panel while standing four feet in front of it (even worse when the door was open...
). I'm amazed that there were never any fires resulting from the bad wiring in this place.
Aside from being deadly, the panel shown in your picture is a fascinating piece. Looks like 30 circuits distributed over three phases, with very small feeder conductors at that. Wonder what all the contactors at the bottom are for? The bussing arrangement beneath the fuse sections would be interesting to examine.
Are any of these panels labelled as to purpose/use? What kind of MDP is in use here?
I recently purchased a panel like this, made by Bulldog Electric Products Corp. These things, if given reasonably good care, were made to last to the end of time!
A very interesting picture!! Thanks for sharing it.
