Conductors to the Secondary C/B follow 'tap' rules.
Hard to believe they are undersized.
Look for OVER TORQUED -- hence stripped lugs on dependent C/B...
As a foreman, I saw that again and again.
Even j-men skip the torque wrench and lay on with a will.
Hence, broken lugs -- loose connections -- hot spots -- trips.
I got to the point that I had to personally intervene, time and again. Clown after clown figures more torque is better. That they've managed to CRACK the lug -- Well, that's a secret best kept from the boss.
Just another reason I started megging everything in sight.
