I seem to remember reading this but can't remember where....can't even find it in the big blue book....
Are there rules about physical separation of circuits on different phases? IOW, do (say) outlets on different phases have to be a certain distance apart, for instance?
If so, can someone please give me a reference? No, it's not for my own wiring... it's a H&S query and I want to track down a document they can point to.
If it is in the Regs, which section please????
