Cutting Off Part Of A Circuit

In my older home i just founf out that all the upstairs ( 2 bedrooms) outlets are installed on the same 20 amp circuit breaker for my kitchen. which might be a reason that when too many things are running this breaker trips. My question is I want to add a 15 amp breaker and isolate all the upstairs on this breaker so the kitchen stays seperate. i Found the romex that is installed to a downstairs outlet that is connected to all the other outlets upstairs but since it is hidden in the walls and i narrowed it down to 3 possiblities upstairs, but i am not sure. How can i test to see which one of the romex wires it could be so i can attach my new romex from the new breaker and just abandon the old wire all together.

PS. when i disconnnect the romex from the outlet downstairs in the kitchen all the outlets upstairs stop working, that is how i know that is the one that brings the electriity upstairs.
      

Can you install 6 recessed light off of one circuit by starting at a switch that is designed to turn an outlet on and off for a lamp that sits on a table.  i've determined all of the outlets in one room are on the same circuit.  The max wattage that will be used in that room if all recessed lights and TV etc are on would be approx. 1,500.  the electrical wire in place is 14 g.
      

I am remodeling my basement and I have a dilema with the wiring. Upstairs I have a switch that can turn on/off the basement lights. Downstairs i currently have a switch that can turn off/on the lights, I guess they both are 3 way switches.



My problem is that I want to install two different zones of dim-able lighting downstairs, but want the upstairs light-switch to turn on both zones. Once downstairs I can have the option of dimming each zone.



How would I go about wiring this?
      

I have 3 bedrooms on 15 amp circuits, 14 gauge wire. Original wiring is one bedroom is on one circuit and the other 2 bedrooms on another circuit. The wall switches in each switched the top half of an outlet in each room. I converted the wire at the wall switch to a 110V feed from the outlet and ran 14/3 from the switch to the ceiling for a ceiling fan. I replaced the outlets since the jumper was cut to isolate the 2 plug ins for switching. Is this whole scenario code compliant?
      

Going through a crazy heat wave here in SoCal, and one of my tenants called to tell me that the electricity isn't on in some of his rooms. He turned on his portable AC unit that he has been using all summer and something may have happened.



Downstairs:The dining room light switch, downstairs light switch do not work. All outlets around them do work though, which is odd cause I would have thought they'd be on the same circuit.



Upstairs: The side bathroom light switch does not work, but outlets all work. In the master bedroom (where the AC unit is located), the master bathroom light switch does not work, nor does the master bedroom light switch. All of the outlets do not work either. I used my outlet tester and it gave me the hot/ground reversed lights. I think this means that the white/black wires are reversed on the outlets (has not changed recently).



I went over, checked all of the breakers. Switched them to off, then back on, did not fix the issue. All breakers stay in the on position without tripping, so no shorts?



Checked all GFCI's, hit test, then reset, did not solve the problem.



We unplugged everything from all outlets, and retried, but it didn't work.



I checked continuity between the main power lines, and the output of the circuit breakers, and all were fine. I did NOT check the voltages though, and will do so in the morning when I stop by again.



Is there anything else I should check?
      

I want to run a new 12/3 to wire a room added on the back of the house. One circuit will be 6 wall outlets. The other will be a ceiling fan and 4 recessed cans. Can I add 2 outdoor lights-using standard outdoor bulbs-to the same circuit as the ceiling lights? Do I use the wall switch(box properly sized) as the junction for the outlet wiring and feed to wall switch for outdoor lights?
      

just wondering if someone can give me a quick answer.  I currently have 7 receptacles and 3 lights on one circuit.  the receptacles are in the living room and the lights are in the basement.  I have just installed 6 recessed lights in the living room. does anyone think that that is too much to add to the circuit.  not much gets plugged in in the living room    T.V.  couple of lamps dvd player, occasional vacuum cleaner.
      

We are just beginning to start with our kitchen remodel. Today, I mapped out all the circuits and this is what I found.



Circuit # 7 - 20 amp circuit to 1 back splash outlet then to 3 kitchen wall outlets, then to a closet outlet and closet ceiling light and then to a side  porch light!



Circuit # 8 - 20 amp to Dishwasher and Disposal



Circuit # 9 - 20 amp circuit to microwave and kitchen ceiling lights. 2 patio recessed lights and dining room ceiling light.



Circuit # 12 - 20 amp circuit to another back splash outlet then to 2 dining room wall outlets.



Circuit # 14 - 20 amp to Refrigerator only



Circuit # 18 - 15 amp to GFCI outlet in garage then that feeds 3 outlets for 3 bathroom outlets and 1 outside patio outlet.



I going to have to add 1 more back splash outlet due to increase in counter space. I'll put the microwave on a dedicated circuit. So I need 2 additional breakers but I only have 1 blank spot in the breaker panel. I guess I can add one of those slim tandem breakers.



So my question, is it ok to have additional wall outlets on the same circuit as a back splash outlet?  If it's ok I'll lighten up circuit # 7 by putting some of those wall outlets on the additional back splash outlet.

Oh, I have 2 20 amp circuits I did not get identified yet! I'll get to those tomorrow.



thanks!
      

Just pulled 7 home runs for kitchen remod. All come across the attic and come out in a 1.5" hole in a rafter blocking. I have about 15' hanging on each 12-2.



The problem is I have farther than 24" to get into the panel, so i dont get the nipple exception to my conduit. Since they're required to be 20A (except the lughing circuit?) i dont have any room for derating.



Is my only choice to run three separate EMT 3/4" and drill new holes in the side of my panel?



Edit: would a junction help me at all?
      

hi...



my electrician walked out on me because i asked him to itemize everything since i wasn't happy about his "extras" that he's charging me for...  i already paid him $9500 of the original $10k bid but he only finished about 80% of the work...



there were a number of extras that he recommended as well as some that i requested...  he decided to jack up the bid to $16.3k...  which included a charge of $1650 for cat6 wiring to 6 locations, $500 for a dedicated 15a circuit for a whirlpool bath...  there were 7 more switches, 13 more receptacles, 5 more recessed lights, 16 more lighting locations and 1 more smoke detector...  is that $6k worth of "extras"?



anyway, i've decided to go with someone else to finish up but so far nobody wants to finish up others' work...  worst case i'm thinking is i'll do it myself...  i already wired a 15a dedicated circuit for my whirlpool tub with no issues so i think i'm up to the challenge...



i just need some guidance to make sure i don't electrocute myself...



here's a photo of the panel...  what's going in the circled area?





also, other than the hots not being connected to the breakers (for the most part) does anyone see anything amiss with this panel?





thanks
