Thanks guys.

A-Line,
Did you buy or make that book?

Do you have a way to account for fluctuating material prices (i.e. automatically tie into purchasing etc.)?

What if I decide I can put (3) #10 & (2) #12 in a 1/2” EMT?

How do you account for the drastic price difference between a GE 2-pole 30 and a Stab Lock?
