Ideally, wire groups are installed in layers and wires are bent at. Learn how to professionally wire and organize an electrical distribution board in this step-by-step guide designed for DIY enthusiasts, electricians, and anyone looking to ensure a neat, safe installation. We cover everything from separating color-coded wires and securing them with ti Neat Wiring:. If you want your distribution box to look neat, there's one step you shouldn't skip: properly preparing and routing the copper wires before final fastening. A tidy distribution box starts with planning the conductor paths so each cable follows a clear, logical route to its terminal without crossing. Start with all your wires at a uniform length. 8 inches out of the box is good. You are using switches that have stranded wires, so you don't need to add stranded pigtails.
