Electrical Control Panel Layout
I don't think there is really a science to how to layout a control panel, but here are some examples of various control panels we have built that may help you lay out yours. If you have a specific question about planning your control system feel free to ask at firstname.lastname@example.org.
Here's a quick video introduction to control panels, below it are examples of various control panels.
