[RE-wrenches] 120% rule applying to conductors

[mac Lewis]

Hello wrenches,

I am looking for advice on how the 120% rule applies to feeders for a
subpanel.  I have this scenario:
150A bus rating on subpanel with main breaker of 100A.  The conductors
feeding this subpanel are 100A rated conductors.  Can I backfeed with a 40A
breaker?

Thanks
