NEVER replace a British fuse with the same rated American fuse

The British Standard for fuses rated fuses by the current that was guaranteed to make them blow instantly.

The American fuse standard rates fuses by the current that they will carry forever.

Back in the days before British Leyland imploded and British cars were common in the US the Bussman fuse catalogues had equivalency charts for people looking to replace blown British fuses.

Bussman Conversion Chart from an old Bussman catalogue:

English Type	American Standard Replacement
50 amp	AGC 30
35 amp	AGC 25
30 amp	AGC 20
25 amp	AGC 15
20 amp	AGC 10
10 amp	AGC 7 1/2
5 amp	AGC 3

Conversely you can just buy the correct British fuse. Pretty much all the British parts houses carry the original spec fuses. This includes the LR parts houses.
