At what point do you start/stop disassembling items. I think you have to at least go by the SOPs, but those are the SOPs regardless of what >than 50% of inspectors in your area do. The SOPs are the minimum and of course some people do more than the minimum. We all pull covers on electrical panels, water heaters, etc. but I would venture to say most people arent dismantling all wall switches/receptacles/plumbing clean outs/etc. Without manuals etc from the manufacturer, Im not sure you can say what is/isnt an inspection panel.
