Just realized why my panel wiring looked like spaghetti, thanks to the inspector in Mesa
Had an inspector walk a 22-zone residential job I finished in Mesa about six months ago, and he pointed at my can and asked flat out, open quote, "did you dress these before or after you landed the hots?" I had been pulling all my zone wires in and tying them off at the top, then landing them any old way, and it showed bad. He spent maybe 90 seconds showing me how he wanted the grounds swung first, hots down the left, commons down the right, and a clean service loop at the bottom. At first I figured he was just being picky, but then I had to come back the next week for a zone fault and finding the bad wire took me 4 minutes instead of 30. Now I bundle and dress as I go, one zone at a time, and it slowed me down maybe 10 minutes on install but it pays back the first time anything trips. Funny thing is my old lead guy in Tucson taught me the opposite, just get it landed and move on to the next can. What is your go to layout in a can when you got 20 plus zones and not a lot of room?
