  1. Stephen, what is your branch avg method? I was taught back in the 80’s we can make a 5% mistake on branch and estimate will still be sound, no mistakes on feeders, switchgear, fixtures. Do you agree?

    • In regards to averaging branch, The owner of ConEst taught me to measure the homeruns, and average the fixtures and outlets, such as 20′ per receptacle or fixture. Since I was trained to measure branch, I am still uncomfortable using the averaging method, but I use it when needed. Yes, you can be a little loose on branch takeoff, but never on feeders, switchgear and fixtures.
