Hello Sixer

It’s been my experience that fuse rejecters come in 15, 20 and 25 amp models. There is no need for a 30 amp rejecter as you have so rightly pointed out that 30 amp is the largest plug fuse made. 25’s are rarely seen as they are really only necessary in certain specific situations where a calculated load on an A/C system or a heating load or the like calls for a 25 amp fuse. It’s becoming increasingly difficult to find even the more common fuse rejecters are most insurance companies are insisting on upgrades to breaker panels. Hope this helps.

I am old enough to remember new installs of fuse panels and typically they would use a pullout for a 30a load like a dryer. The last one I saw installed was 1971 tho.
If you use the S adapters, there is no code reason why you can't install one today. I think I would fight an insurance company that screwed with me if it was code compliant.
One thing you need to watch for is there is an S adapter that will take a 20 and a 30. If it is installed on a 20a (12ga) circuit, it looks legal but it is not. I found a box stuffed with these adapters and a 30a fuse in half of them. Some were even on 14ga wire so it was impossible to be code compliant. I strongly recommended a replacement panel.

Greg:
I'm in agreement with you that there are no code restrictions on installing a fuse panel. However, one would have to look really hard to find one I believe.

Plug fuse panels are becoming very rare, however I do come upon one occasionally. A 12 circuit plug fuse, 60 amp service was 'discovered' on inspection of a solar install. I strongly suggested to the HO that the funds she 'saves' from the solar she should invest in a new 100 amp service. LOL

Back in the day, "fusestats" (S-Fuses) were 'stock' in the trucks of the EC I worked for, as he did a lot of 'inner city' work, and most of the multi family dwellings had fuse panels. 30s were a common find, lots of blown 15s and 20s on the floor, and yes, there were a few fires due to overloads on the 14 Ga. conductors.

Fusible panels were still in the catalogs in the 1970's.
