Bussman Point by Point AIC Calcs
Bussman Point by Point AIC Calcs
(OP)
I've been evaluating the Point by Point method of AIC calcs that is in the Bussman Fuse book and also indicate in other literature. They have calculation for an f factor and an M factor. I'm trying to figure out where they come up with the M factor (the multiplying factor) 1/1+f.

Where f = some function of length, cable type, voltage, and and available fault current at the "beginning" of a system(in many casees this will be available fault current at the secondary of a transformer)

exp^-f(x)
where f is some real value of function f(x) and x > 0.
OR maybe its some kind of approximation for a summing series. I'll check into later this evening...I'm studying for the FE anyway.

As for your basic question, ask Bussmann.
