Darn Former Owners/contractors (monkeys) - Kitchen

My wife and I are doing some minor kitchen remodeling in a few months (new sink, countertops, backsplash, adding disposal).  I was looking at the electric to see what I was in for.  There is currently a switch located where you would locate the switch for a disposal... but it shuts off the dishwasher.  WHAT?  WHY?



So I look into the dishwasher circuit.  20a at the panel, wires run in conduit to the switch location.  Out of the switch box comes 14/2 NM-B (WHAT, undersized!) comes out under the drywall and over to the junction box on the dishwasher.



So, what do you guys see as the solution here?  I was thinking to run a new 20a circuit, with 12 gauge THHN from the panel to the switch box, then splice that to a new piece of 12/2 NM-B to the dishwasher.  Question: can the NM-B just lay behind the dishwasher like that?  Should it be BX? 



The 14/2 NM-B would be removed and 12/2 run from the switch to a new outlet under the sink for the disposal.  So, I would end up with 2x 20a circuits: one for disposal, one for dishwasher.



Does this sound like a solid plan?

Hi Everyone! I ripped out my old dishwasher to replace it and found a hardwired cable consisting of RED and WHITE but NO ground wire. Weird, right? How should I hook up my new one? I have an available outlet adjacent under the sink. It contains my undercabinet lighting which is low voltage. Also, when I disconnected the old dishwasher and turned the power back on, HALF the kitchen outlets are dead. Is it a coincidence or is the hardwired dishwasher somehow linked to other outlets. Since the hardwire it's not connected to anything at the moment (it's capped off while I decide what to do) the subsequent outlets have no power? What gives?
      
I am new to the forum so kindly bear with me.  I live in Mesa, AZ and have just had a PEX repipe done to bypass my copper hot water lines.  (God don't ask!  A real problem here with slab foundations.  I already had my kitchen jack hammered once.  It is NOT pretty!).

It seems really odd to me that just because it is a dedicated circuit  that code would not require that circuit to be GFCI protected.

I have a dedicated 20 amp duplex 12 AWG wire outlet under the sink and it is within a few inches of the water lines.  The outlet serves a switch for the garbage disposal and serves my dishwasher which is always hot. 

  Now that I have all my maple cabinets pulled out I thought I might change the outlet to a GFCI just to be safe.  I have a ground wire, a red wire, a black wire and a white wire.  As it is dedicated I think I should use the LINE sided instead of the LOAD side but I am not sure where the wires should go.

Could someone give me info on this?  It would be greatly appreciated.  Thank you.
      
I completed my whole house rewire last Fall (took 2 years and severely tested my wife's patience). I read 5 wiring books in the early stages but read Rex Cauldwell's Wiring a House with his above code suggestions near the end of the project and now im obsessing about some of the stuff I didnt do. What do you guys think of some of the suggestions, specifically,



1. Driving 8 ground rods and the wire must be continuous (I drove 4 but the #6 copper wire from the panel to rod 1 is 1 wire and the #6 wire from rod 1 through rod 4 is another wire but both are properly clampled to rod 1 with an acord clamp). Funny, even with 4 rods there is almost no current through the rods versus 2-3 amps through the traditional cold water pipe ground



2. 1 circuit for each duplex receptacle in bathrooms. Since I have a quad in each of the batchrooms, that would be 4 circuits instead of 1 (code allows an unlimited number of bathroom receptacles on one circuit which does seem odd)



3. Nothing shared with kitchen counter receptacles (ie kitchen wall and dining room on their own)



4. Dedicated circuits for everything - I added dedicted circuit for fridge, microwave and dishwasher/disposer, but did not separate the dishwasher disposer onto 2 circuits. There used to be what I called "Circuit X" which did kitchen counter, microwave, dishwasher, disposer, fridge, 2 kitchen counter outlets, dining room and 1 outside outlet. Wife frequently blew that one. Circuit X was divided into at least 5 circuits during the rewire



5. No switch loops - did 5 of these to save on carpentry/avoid certain box fill problems. Now 2011 code says no switch loops without a neutral. Oops?



Just wondering what you guys think.
      
I was going to put this in this thread  Junction box in stud wall behind drywall?  but, decided to start a new one.



Two nights ago while sitting in my kitchen the can lights in my soffits above my cabinets suddenly went out. At first I thought my daughter or her boyfriend was messing with me and reached around the corner and flipped the switch. Nope. Tried the other switch near me and nothing. Everything else in the kitchen worked.



Thinking tripped breaker for a moment...nope other lights work on the circuit. Can't be 6 CFL's burnd out at the same time. Hmmmmm?



Background:

Kitchen was remodeled 12 years ago. Drywall was in good shape so not removed. Added circuits for Fridge, Microwave, Garbage disposal, Stove (gas),Dishwasher, range hood, and countertop recepts. None of these are tied to lights. Original task lighting was 4' tubes over countertops above cabinets. Remodel added sofits and can lights from these two feeds



Started tracing circuit path to look for loose/broken wire. Found no power at lights. Checked power at breaker...Good. Follow wire to kitchen, no junctions. Wire disapears up into wall below the switch area. Check for power at switch box. Yep, power there. Power off and pigtail Neutral/hot  wires at a can light together. No continuity on the load side of the switch circuit. Broken wire somewhere between the switch and the lights. Fortunaly there is an attic space above the kitchen. Unfortunatly, it is a short headroom ~3' or less and full of blown ihn insulation. In I go to trace the wire.  after about 10 min up there I found the burried junction box. At some time in the past there used to be a single light in the center of the "U" shaped kitchen cabinets. This was abandoned and the box was drywalled over...still in the location for the light hookup so the cover was not readily accessable. found a tightly twisted Ground, Neutral and Hot with nuts. All looked good untill I Started messing with them. found that one of the hot leads had broken right at the insulation on the wire. Looking at it closer I could see some arc burn at the break. I am thinking that when the handy hack that did the job nicked the wire he did not know or care and tristed it together anyway. It took over, to my best guess, 20 years for it to fail.



Moral... It can happen
      
New appliances coming in. No change in service, so I believe that existing wiring can be considered grandfathered. Please correct me if wrong. BTW: we're under 2005 code in my locality, but I go with 2008.



Currently, the kitchen is wired all 15-amp except for non-counter-top receptacles. (I know, opposite, and wrong, but that's the way it is)





Can dishwasher and disposal be on same 15 amp circuit? (This will be a new circuit, so perhaps I need to run 20-amp?)


Current range wiring is 3-wire on a 40 amp breaker (3-pole). Can I still utilize a 3-prong receptacle here?


Does the kitchen wiring have to be upgraded to provide for 2 SABC (currently, only 1), and 20 amp?



      
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!
      
Hello,  what could be the cause of the kitchen sink faucet stream feeling a slight tingling sensation when the garbage disposal is running?

Can't be good, I know!

Possibly a grounding issue?  200 Amp service w/ two subpanels.

House is about 25 years old.

Thanks for any help how to start troubleshooting.
      
I have a mwbc where one is running my kitchen outlets, and the other is running a dedicated circuit for the disposal. the breakers are adjacent in the panel, so they are on opposite phase and share a common neutral and ground. I was updating the outlets and so turned off only one of the breakers. when I tested the line to make sure it was off, my voltmeter still read about 10 volts. Is this normal? there were no appliances connected to either circuit.
      
I'm renovating my 1960's ranch house and the kitchen circuits alone are causing me to put in a new breaker panel. The house is 1200 square feet with a 1200 square foot daylight basement -- 3 BR, 3 BA all together. And everything is electric, including the heat.



Please check out my proposed circuit plan for the kitchen and laundry areas. I am trying to figure out which circuits I can combine so that I will still have room in my new 40/40 200A Siemens panel to wire the rest of the house.



FYI, the house is located in Washington state and I have pulled a permit. Thanks in advance for your guidance!
      
Hello all, and thank you in advance for any help you can provide! Here is the deal I wanted to put a bathroom exhaust fan in and was told I could come off the existing switch to cut the wire, install a junction box, tie the wires all back in adding the wires for the fan. Trouble is the bathroom light stays on with the switch off. Turn the switch on light dims and the fan now runs, switch off fan shuts off light goes bright used black to black white to white where oh where did I go wrong!?
