What it concludes

• You need 36 inches of space in front, 30 inches across, and up to 78 inches of height to install a sub panel.
• A sub panel setup typically requires four wires: two hot, one neutral, and one ground.
• When drilling through load-bearing 2x4 framing, you can only cut a hole up to 40 percent of the depth of the studs.
• Conduit fill should be kept to about 40 percent to allow room for flexibility and maneuverability.
• Bus bars inside the panel require 20 inch pounds of torque, while neutral and hot lugs require 50 pounds of torque or 36 inch pounds depending on the specific Square D Homeline breaker manufacturer specification.
