Hi Peter;

I've seen this same problem with AGC glass and ceramic fuse holders. Old 
auto fuse blocks and Trace C30s were notorius for this problem. I could 
always tell with glass fuses because the link would blow on one end 
instead of the middle. I would just bypass the whole assembly with 
another type of fuse and holder. I've seen this also with some Manus' PV 
combiner fuse blocks too.
Class T & RK 5 fuses and holders don't seem to have this problem. The 
non listed ATC spade fuses are even better. I group the AGC, ABC, etc. 
fuse holders in the same category as 12 volt cigarette lighter 
connectors: generally junk waiting to overheat and meltdown. I stay away 
from all of those types except for low current applications (< 5 amps). 
I'm sorry to hear a relatively respectable Manu like Shell has put their 
name on this stuff. As always, its going to hurt the entire industry on 
the percieved reliability issue.
