I have inherited a house that has been in my wife's family since 1860. I do not know when it was electrified, but it seems to have skipped knob and tube. There is a lot of fabric-covered wire, and also some more modern romex wire. On examining the fusebox (yes, fuses, no breakers) I see that both the hot leg and the neutral leg have fuses in them.
My long-term strategy is to replace the fusebox with a modern panel with breakers. In the short term, I have purchased 30 Amp fuses which I intend to install in the neutral fuse positions. (The hot-leg fuses are 15 or 20 Amp.) My thinking is, since the hot-leg fuse is of a lower rating, it will blow instead of the neutral leg fuse.
Is this an acceptable solution? Is there a better way to ensure a continuous neutral leg connection?
