Ken and list:
The SAE fuses are rated at their holding current. That
means a 20 Amp fuse will carry 20 amps forever and will open at a
current level of 40 Amps or less (usually somewhere between 30 and
40 Amps). A Lucas fuse is rated at the current that will cause it to open.
For example, a 35 Amp fuse will carry 17 Amps forever and open at 35
Amps. Therefore when replacing aLucas fuse with an SAE fuse divide
the current rating by 2.
