Pro tip: I zip tied every wire tight for 6 years and a panel in Mesa finally showed me why that was dumb
Early on I was proud of how neat my panels looked, every wire cinched down tight with zip ties at every stud, super clean. Then I opened a 12 year old panel at a house off Brown Road in Mesa and half the wires had tiny kinks right where the ties sat, plus the cat5 for the keypad was crushed flat. The old installer who trained me never cinched anything, he always left a little slack loop, and I finally got why. How much slack do you all leave behind the can?
