As mentioned in an earlier post, my primary job is low voltage installations, but I am currently remodeling my home and handling rewiring a lot of the electrical into a more organized, clean, and (current) code compliant manner.
To that end, I have a couple questions on the NEC code that I am hoping some clarification / confirmation on.
1. There is an exterior door that swings open against a short wall that is around 3 feet in length. At the end of the 3 ft, there is another 3 ft interior doorway between rooms. Since the wall behind the doorway is over 3 feet, I am guessing that I am stuck adding a receptacle to the wall, correct? There are not any exceptions for walls that doors essentially open against huh? Because of the door opening, I see no situation where the outlet would ever be used, but I also don't see any exceptions to it. Since this is a remodel and there is no outlet there now, can it not be installed because I am technically not making any changes to that "circuit" or wall section, even though I am running a brand new circuit for the rest of the room?
2. Is it ok to put a hallway receptacle on a bedroom circuit?
3. I have attached a visio of my current plan for the layout of the SABC for he kitchen / dining area. Can anyone see any issues with the current plan or have any suggestions for laying it out in a better way?
4. I have attached a pic of a shallow old work box I found that is 17 cubic inches. I have an interior wall constructed with 2x3 and standard old work boxes are 14 cu inches which would not allow a plug to be installed in it on a 20A circuit (Box fill, 2.25 * 7 [2 device, 2 conductors in, 2 conductors out , 1 ground] = 15.75). Can the "flat, enclosed" portion of the box be placed behind the drywall and still be code compliant of being accessible because of the opening exposed through the drywall for the receptacle?
5. When running a switch loop with 12/3 or 14/3 wire now that a neutral is required at the switch box, is there a particular requirement (or general recommended standard) for which wire supplies the hot to the switch box or is either way used since both black and red are "hot" "color codes"? IE, the old way you sent the hot to the switch box using the white wire in NM cable provided it was taped black at both ends and the black HAD to be used to return the power to the fixture. With 3 wire cable does it matter which cable sends power to the fixture? I intend to use the red to supply the switch and the black to the fixture, but I was just curious if there was any established rule regarding this.
I appreciate the time to quickly answer these questions.
