Is there a limit on how many #12 wires can be bundled together inside a panel with (electrical Ty-Rap) zip ties? Assume no limit for grounds, but what about neutrals and hots? Have 19 max on a side.
I use zip ties and wax string.
You kick at old school. I like the looks of wax string in the old control panels. I feel guilty about having to snip those.
My Dad was an artist with safety wire. He had several tools he made and he never owned or used safety wire pliers. WWII era and on.Yes! kinda like a nice safety wire job in the aviation world!
