MxSlick: This old theater may well have been wired by some ancient electrician who stayed around to haunt the joint. It had some very strange wiring. The main service equipment was located in a mechanical/air conditioning room at the back of the building. There were two enormous main EXO disconnects. I remember one contained three poles and three fuses, plus neutral. The other switch had three similar poles, but a single line/load conductor to only one fuse (?). I never did find out what kind of voltages were coming out of this stuff - it made me nervous to go anywhere near this mess. Both of these switches dumped their load conductors into a large wire gutter with more exo's than you could shake a stick at.
I wish I still had one of those strange glowing fuses. I don't even know who manufactured it. It had a glass body, and the small cardboard label that resides behind the fuse link was gone (burned away, maybe?). The only identifying mark was a "30" stamped into the center contact.
