ps. Bedroom closet. Definitely cloths. How big is it. 8 fuses. With the two black pull outs on top of the fuses. I can't think what those are called. When you pull those out two round fuse bars are in each. Once again i can't think what those are called.
The round fuse bar what we called them cartage fuse and one of them is the main that useally on the left side of the pull out location while the right pullout is used for range.
The round fuse which it screw in what it called plug fuse.
And that is old style fuse boxes and they are pretty much done useable of their service life.
Check with your local codes if they can allow to remain the exsting location ( I really doubt it unless they say ok only in writing )
Normally I useally converted to the junction box by removing the guts and make a note on them saying " junciton box only no fuses inside "
