I have a cutler hammer fuse box. The main box # 4336h1312 it is missing what I believe is the fuse distribution box or circuit breakers. 100a on top (2 spaces), 30a (2spaces) on bottom and 60a (2 spaces) on bottom. I really am not sure what the part is called. The fuse box was made in may 1957.

What are you trying to do? Do you have an old box that you are trying to install, or are you having issues with your current box. Please try to explain a little more.

How about a picture. Sure it is a fuse box? Does it have tube fuses and screw in glass fuses?
