Rockwood 2290 fuses ? What to use

[Philandviki]

I bought a used rockwood 2290. The fuses the owner had in it when I bought it are 75 amp fuses ! They seem way to big . What should I use ? 15 amp ? 20 amp ? I really don't know ? Thank you !!

I would replace them with the correct fuse.
Something that large IMO should not be in a TT.

How do I know what the correct fuse size is ? I can't find that info anywhere ?
Thank you

Here is an example of fuses sizes for TT in power panel....

Great thank you ! So it seems I really couldn't go wrong if I put 15 amp fuses in there ...
I can't imagine why this person we bought it from had 75 amp fuses !! That's crazy !!

Are you sure that they weren't 7.5 amp. That size is used but infrequently...control boards for the fridge or A/C. The DC panel is usually 15A fuses.
