I have a 200 amp panel that is pretty crowded. I just ran 3 12/2 lines to the box. One is for a series of 110 outlets and 2 will be dedicated 220 outlets. All of the current wiring comes through the top of the panel. Should I try to squeeze the new wires in the top and run them down to the open slots or just come in through a knock out in the side of the panel?
How many wires can go through each knock out? Should I use the plastic piece in the knockout or the traditional metal clamp?
I would like to keep the box clean and professional
Thanks
