If anyone else on here likes discussing and tweaking electrical plans [read: is as much of a geek as me], here's your big chance. I feel I have it about where I want it, but welcome input. I read the RVIA and ANSI publications and have adhered to them as far as I can see, but there is always room for improvement. As to my experience level, I own a handyman-type business and have years of construction-related experience but no formal training. I do sit around and read the NEC and other publications, as well as books on electrical theory and application, but I am still an amateur.
I tend to over-plan things, because it is easier to make changes on paper than in the field. I therefore spent quite a bit of time designing a complete schematic for my coach. I am not ready to install all of the included loads or circuits yet, but the idea is that if I have a map I can build it in stages without painting myself into a corner. It includes 110V circuitry (from the point of entry into the bulkhead) and 12V circuitry (not inclusive of all OEM chassis circuits or of chassis grounding portions of circuits). It does not include wire size or type information, and load wattage is largely absent, except for some sticky notes regarding large appliances. There is a legend included (but you may have to rotate the image to read it). I designed it on a 24"x34" pc of posterboard, and then scanned that plan to a PDF file, which allows the addition of sticky notes.
