Hello. I'm looking to build a control panel using the diagram thats attached. My question is this... I'm no electrician, but, I'm good at following directions. What gauge wire is used within the box for each run? Like I said my electrical knowlege is slim and what I do know I've learned from watching other people. I understand each component of this system and what its used for but it's just the gauge of wire that confuses me. Thanks in advance.
