New guy on the block here, have lurked and read for a year or so, just wanted to add my .02 ..... I have wired houses in SOCAL, Denver, St Louis and most recently Oklahoma. I actually wired a bunnch in SOCAL that looked just like the one pictured wouldnt happen to be a KB build would it?? Bundling wires through a TA is common and encouraged in Cali and Colorado, forbidden in St Louis, and "not encouraged" in Oklahoma. St Louis goes so far as to ban multiple wires through any KO or even a hole drilled in a 2x4. Makes the top plate look like swiss cheese when feeding all home runs into the panel.
