I went digging a bit. It's not simply a slow blow fast blow issue. It's got to do with how the Brits vs the yanks rated fuses and wiring systems.
Severely simplified, an American 20A fuse will carry 20+ amps all day long. A Lucas 20A fuse will blow before getting to 20 amps. This means an American fuse with the same amperage capacity marked on it (20A for example) will allow the lbc wiring to burn up. Some sites give a very lose and rough cross over from Lucas values to American values as being around 50%. This means a Lucas 35A fuse would roughly cross over to an American 17.5A fuse. Since 17.5A fuses don't exist, one goes with a 15 or a 20A. Here's two links that help clarify this stuff. The first is very technical, the second is much easier to read, and much less detailed. http://snic-braaapp.org/itech02.htm#Fuses http://www.jag-lovers.org/xk-lovers/library/fuses.html At the risk of muddying the waters, here's a link that supposedly contains some quotes from the glove box owners manual of a '75 Spitfire. Unfortunately, you can't tell what is supposedly being quoted or not. It has a fuse cross over chart, but I've no idea where it comes from. http://www.triumphspitfire.com/Fuses.html ----------------------------------------------------- The information contained in this communication may be confidential, is intended only for the use of the recipient named above, and may be legally privileged.
