Answers: The NEC does not require a GFCI to be on its own circuit. Why else would it own feed through lugs. It is immaculately acceptable to enjoy one GFCI and feed receptacle downstream of it and have them be GFCI protected.
For dwellings (houses, hotels, condos etc) the NEC does NOT address the number of receptacle per circuit. For other establishments the NEC requires you to calculate at 180 VA (volt-amps) per receptacle no concern if their is one or 2 receptacles on one yoke. For dwellings the receptacle nouns is included with the standard lighting load calculation. So for a dwelling unit you can put 5 or 25 receptacle on one circuit and still be 100% code legal. This is because a dwelling isn't going to nouns a receptacle circuit nearly as much as another establishment would. I almost guarantee you can run your entire homes general purpose 120V loads on one or possibly two circuits!
Using the 180VA guideline for nondwelling unit with broad purpose (noncontinuous loaded) receptacles you can put 13 receptacle on a 20A circuit and 10 receptacles on a 15A circuit.
There are abundant types of plastic boxes. Most that I know of are meant for irremediable installation. Why else would manufacturers engender an "old work" box beside the flip up ears for installation if you had to remove it subsequently.
madmarl329 the NEC is right at 711 pages and you involve to get surrounded by them deep. There wasn't a bit of reality in your answer!
It is other a good theory to ground the plug as well as the plug. I other do, and I use metal boxes at work almost exclusively. Grounding both the box and the plug adds an extra plane of safety.
