The GFCI outlet (A) by the vanity in my bathroom is not working. When I tried to push in the reset button, it would trip the breaker that controls the bathroom. I checked every single outlets in the house (including the ones outside and in the garage) and all of them works except the bad GFCI. The only other thing that may be connected to this GFCI (A) is the other GFCI (B) near the other vainity in the same bathroom. They are about a few feet away. I knew that because every time I flipped the break back on after pushing A's reset button, B's reset button is always depressed (was pressed before). So I opened up the GFCI (A). Two lines are hooked to Load and two lines on Line. Ground is fine, not touching anything. When B is working (reset pushed in), both Load and Line of A have power. However, if I push test button of B and then test A again, Line has no power but Load still does. This is confusing, since I thought Line is the power source. If Line does not have power, Load should not have either. Does this indicate GFCI A is broken? Should I replace it?[ATTACH]58885[/ATTACH]

Hello, We just bought a home - a 1920's 4 bedroom, two-story house with basement and unfinished attic. The main floor and upstairs are knob & tube wiring. I would like to work on rewiring the upstairs first - which is three small kids bedrooms and a full bathroom on the end of a hallway. The bedrooms have no overhead light, and the only receptacle in each bedroom is built into the wall sconce which has switch for the light - all located away from the doorway...oh, and all plaster walls!! Here's my plan I've been dreaming about: The breaker box is in the basement. I think I have a strategy of running cable up to the attic through interior walls and then back down to the bedrooms and bathroom. I was thinking of doing the three bedrooms receptacles and lighting on a 20amp circuit, a 20amp circuit dedicated to the bathroom receptacle and light, and a 14/3 dedicated to interconnected smoke detectors (dedicated required by code, IC HW smoke detectors desired by the better half). So about 15 receptacles and 3 overhead light fixtures for the bedroom circuit. Is that overloading it, or should I pull a second 20 amp bedroom circuit and split the bedrooms? The hallway I was going to do on a main floor circuit, since I would like to have a 3 way switch for the light over the hallway/stairs (only switch is upstairs right now). My thought was that this would allow for some lighting if the one bedroom circuit should trip. An idea came to mind on how to deal with cutting in all these receptacles - would it work to put an abrasive wheel on a skilsaw, and cut a 8 inch wide track out of the plaster all the way around the room, install electrical boxes and wire, and then patch the track with drywall and mud? Assuming I can manage the dust? What do you guys think? I appreciate all questions and input!
