If I was going to label a fuse box, I'd do what I do when I label things. Use my Brother P-Touch. Easily one of the most useful purchases I have made in the past five years.

Of course it won't document a fusebox, but because I don't work with fuseboxes for a living and fuseboxes are not a hobby I am likely to take up, I can't see myself ever needing to do that enough times that finding a fusebox document would be easier than looking at a fusebox I already labeled.

It appears that "fuse box" is used as an anachronism here, as those most certainly look like circuit breakers, and I was expecting something more related to automotive fuse boxes.

Have you considered adapting this to Ethernet switches?

They have a similar layout…

Labelling ports of managed switches seems kinda useful, though never seen it done. (I do it at home)

Does this also support the normal north american vertical fusebox?
