Re: outlets and junction box
Well, I can certainly understand why the OP hasn't returned. He asked a question about outlets, a commonly used term to refer to the receptacle, cover plate, mounting box, mounting hard ware, and associated wiring. It may not be a scientific, engineering, code, or nit picking individual part name but is prevalent in everyday language used by home owners and trades people alike just like saying they want a switch installed and meaning the switch, the box wiring etc.
The NEC requirement is based on the assumption that electrical appliances will have standard 6 foot cords and no mater where you place it on the wall the cord should reach an outlet without and extension cord. That allows receptacles to be 12' apart. However, as I said before it doesn't matter what the NEC says, what matters is the interpretation and requirements of the locale jurisdictions and their inspectors. Most I have dealt with require the outlets to be no more than 6' apart and one even required them every 4'.
