Thank you, Jim Katen. Yes, I suppose I mean "two-pole 50-amp breaker" -not- "double-throw 50-amp breaker." Appreciate the terminology correction. One detail I forgot to mention: the cabin's fuse panel schematic shows the Range Block being fed at its bottom from the Main Block's top. Thus, I suppose it is a 100-amp panel as its schematic is identical that way to the schematic in this thread. Next time I'm there I'll pull the Range Block and see what's what. Thanks again. -Jake in Durham, NC

My apologizes for reopening a very old thread, but the pictures and diagrams herein are most illustrative of my question. My thanks to the original posters! I'm trying to understand the electrical system in my friend's old mountain cabin. There's been extensive electrical work done to the place over the years. I'll provide as much detail as possible, then ask my question at the end of the post. There's a new circuit panel in the kitchen. And there's a Main/Range fuse block in the utility room that powers a water heater and the lights for that part of the house. The kitchen circuit panel has a double-throw 50 amp breaker labeled "Utility Room." Turning OFF the "Utility Room" breaker in the kitchen circuit panel removes power from the utility room. Looking at the Main/Range fuse block... there are wires connected to all 4 terminals on top (the 2 designed for supply and the 2 designed for a range). The wires to the 2 Supply terminals are old. The wires to the 2 Range terminals look new. The water heater is powered from the bottom terminals in the normal fashion. There is no range in that part of the house. Here's my hypothesis and question: Is it possible that the 2 wires connected to the Range terminals are actually supply lines from the kitchen circuit panel? And that the 2 wires connected to the Supply terminals are unused? (Where the ends of those latter 2 wires are is another question.) Looking at Jim Katen's above-posted schematic, this looks possible, given the (what I'll call) "backplane" connections between the Main and Range sides of the fuse block. Thanks very much. -Jake
