I am selling my house that was built in 1964. It has a Square D fuse panel. The buyer's inspector wrote it up for having double tapped fuses. Double tapping is allowed by the NEC if the panel is listed for that. The only thing I can find is that each terminal says "8-14ga". Does anyone know if double tapping would be allowed in this case so long as the total area of wire in the slot doesn't exceed that of an 8ga?

I have fixed several already by pigtailing so I have only one wire per fuse, but I am curious if anyone knows the answer to this. Thanks!

No, it doesn't matter if the area adds up to #8 or less. The device has to be listed for more than one conductor. This info may be found on the sticker on the panel door, assuming it is still there. The best bet is to pigtail them. Also, since you aren't changing it out to a breaker panel, be a nice guy and put in the type S adapters so that only the right size fuse can be inserted.

Most Square D breakers are listed for one or two wires. They started putting the listing on the side of the breakers in the late 1990s. Before that, you had to look it up in their book.

I would agree with InPhase above, and simply pigtail the wires with a wirenut, and land only one wire under each breaker. It's likely the easiest way to satisfy the home inspector.

If it were me, I'd likely argue it, but I also have a copy of Square Ds spec. book in my van. Plus I have a copy of the NEC, and know where the part about double-lugging is.

Thanks for the info. I couldn't find anything one way or the other and it's too old to find any specs on Square D's site. I'll just finish pigtailing them. I know with the neutral bar you can't double up regardless of the size of the slot but I wasn't sure about these fuse lugs.

I know before early 90's it was common to see double up netural conductors on netural busbar but now it no longer allowed to do that for safety reason.
