Circuit Breaker as a distribution block/stud
Can a Stud Style Circuit Breaker be used as a power distribution block?

Re: Circuit Breaker as a distribution block/stud
Yes, it will make a dandy distribution block. The terminals are pretty exposed, and vulnerable to accidental short to ground from a wrench or belt buckle. To avoid shorts, I would cut the studs as short as practical, and cover the exposed part of the stud with a plastic cap or "liquid electrical tape" or plastidip.

Re: Circuit Breaker as a distribution block/stud
I like the idea of 20A and 30A fuses to the ignition box and alternator. The 40A breaker will protect all of the wiring downstream from it's location. In addition, if the alternator fuse, alone, blows because of an alternator wiring fault, you will still have ignition until your battery runs out of juice.
However...First, I am not as knowledgeable about the required fault protection as others here (VetteVet, are you listening? Gmachinz?) Secondly, by wiring direct from the alternator to the battery -- bypassing the main junction point described in other current posts -- you are disabling the ammeter gauge functionality. Maybe that's OK. I suggest you read recent posts by Mick Je and OregonNed, if you haven't already. Then post back here with a description of your proposed battery/alternator wiring and get comments from the group about the overall plan. Good luck and stick with it. We'll help you figure it out. Especially those other, smarter guys.

Re: Circuit Breaker as a distribution block/stud
I looked at those posts. Vettevet had a good schematic. it has a gen/reg vice alternator but I will use it for good reference. MSD box requires a hot wire. I am eliminating the fusible link thinking I would rather replace a fuse and not have to further cobble up the wiring. A common distribution block is a lot more expensive than a circuit breaker. I hope to get my electrical straightened out, then on to carb and column shifter probs.
