Using 60 degree ampacity for less than 100A

[Dennis Alwon]

what is that rule this is a single fam dwelling with a 200 amp service i put a 100 amp brk in the main panel and put a main lug with a 90 amp brk and a retention clip in the garage that is detached so would you say that would safice for the rule

That would work but remember if you are under the 2008 NEC you would need 4 wires and you also need to use ground rods or other electrodes.

. . . and bonding bridge

If, by bonding bridge, you mean a bonding jumper between the neutral bus and the EGC/GEC bus and/or the enclosure, please remove it.
