Dedicated Circuit Question

When you install a dedicated circuit, say for a washer or refrigerator, does the NEC require the receptacle to be a simplex rather than a duplex ?

I have a 20 amp circuit with two 15 amp duplex receptacles on it; can I also put a 15 amp simplex receptacle on this same circuit?
      
If you have a 20 amp circuit going to your bathroom vanity, can you have two 20 amp receptacles on it, one a GFI receptacle and the other a standard 20 amp receptacle wired to the load terminals of the GFI receptacle ?



Or does the code require each receptacle to be a GFI on its own circuit ?

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.
      
Hi all, this is my first post, so...my kitchen was just renovated and the electrical outlets are on the walls and I wanted them in plugmold under the cabinet. Why didn't it happen?  Long story, but I'm doing it myself now.  The electrical receptacles are on 2 separate circuits with a gfci receptacle on each and neither circuit has a receptacle outside the kitchen where I can put the gfci's, so I'm putting gfci breakers in the panel instead. I've run into a different problem on each circuit that'd like some advice on.



Circuit 1: this is a 20 amp circuit.  I have to plug this circuit's neutral wire into the gfci breaker, but I couldn't see which neutral wire matched the hot wire (buried in mess of wires) and I don't have a continuity tester so I just pulled one neutral at a time (tedious) until the circuit failed, but it never failed. So I did this again for every neutral...same result. This circuit shares a few boxes with other circuits so I'm wondering if the neutrals on different circuits are tied together somewhere, and if so I'm pretty sure, but not completely, that that's not going to work with the gfci breaker.  So I didn't install that gfci breaker since I'm not confident it would actually gfci (yep i verbified gfci).  What do you think?



Circuit 2:  this is a 20 amp circuit.  This circuit currently has the refrigerator, gas stove and range hood, and then a gfci in front of 3 electrical receptacles, which already sounds bad since I thought the kitchen receptacles required 2 dedicated circuits. I replaced that breaker with no problem, but it tripped after a few minutes and continued to trip every few minutes. I haven't changed anything else on that circuit yet and it's never tripped before, but now it is, so I put the old breaker back for now. The current gfci receptacle is only protecting the 3 outlets since the appliances are ahead of it. I know you wouldn't normally want the appliances gfci protected, so do you think the refrigerator motor may be a problem?  Do I need the appliances on a separate circuit?  What would you suggest I do?



Thanks, and if you're wondering "why all the effort?", it's partly because I'm meddlesome, partly because I'm bored, and partly because the backsplash tile is to be on showcase, not the electrical receptacles.
      
I am thinking of purchasing a WineKoolr used but after looking at the manual online it states that it must be plugged into a "Dedicated separately fused, grounded, 15 amp 100-120v line." The price I can get this at is awesome, but I live in apartment and am not sure, but think I only have 1 dedicated line at all, for the fridge. The previous owners said they just had it plugged into a normal outlet fine, but I want to know if it is a serious issue to do this? I really want a nice cooler for my beer cellar since I have no actual basement, so I am really hoping I can make this work in my home. Thanks for any help!





*Someone asked me on another forum what breakers I have for where I want to install it, and its in my second bedroom.  The breaker for those outlets is a 15A.  They also said that it probably says that in the manual to cover themselves legally but I should likely be just fine.





**

Well I turned off the breakers until I found which was for the outlets in the spare room.  As far as I can tell, the only things on this circuit are the spare bedroom outlets (not the lights), and 1 outlet in the hallway.  Nothing is plugged into any of these and its a 20A circuit.
      
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!
      
That means it applies to the entire country

Permits & Inspections are usually required for ALL electric work

It may not be legal for you to do your own work, Check with your local Building Dept

This thread will be added onto as a form of "Cliff Notes" for the NEC

If there is something that needs to be corrected, or if you wish to add to this thread; please let us know



The NEC is available online, you may have to sign up for an account to view it:

http://bulk.resource.org/codes.gov/



New Code book comes out every 3 years, it is not always fully accepted by States & sometimes not until 1-2 years later

Local codes can vary from the NEC



210.23 An individual branch circuit shall be permitted to supply any load for which it is rated (some think you can only load to 80%)



210.50 Required Branch circuits

14g wire is rated for 15a, 12g wire is rated for 20a

15a outlets ONLY on a 15a circuit

15a/20a are allowed on a 20a circuit

A single 15a receptacle is not allowed on a 20a circuit

AFCI protection is required almost every where under NEC 2008

Exceptions are GFCI required: bathrooms, kitchens, laundry (GFCI if sink within 6' of receptacle), garage & outside circuits



Bathroom requires a dedicated 20a GFCI protected circuit that can serve outlets in multiple bathrooms

OR

Outlets & Lights in One bathroom



Kitchen requires 2 dedicated 20a GFCI protected circuits for counter (no lights)



Laundry area requires a dedicated 20a GFCI protected circuit

Ya know when your g/f or wife says, 'Don't you DARE talk down to me?'... well, I AIN'T your g/f or wife but what i IS is so DYI challenged that anything but the most basic explanation will cause my brain to short circuit.



To prove how DYI-tarded I am, I bought a used staking washer/dryer because it was what I could afford.. but now I can't plug it in. The plug is a large crows-foot deal but my outlets are standard USA deals.



I know it can't be as simple as changing the cord to a standard 3-prong.





KENMORE STACKING WASHER/DRYER  MODEL NO:  417.90802992

WASHER 120/240V

DRYER   240V

APPROX 4 YEARS OLD

EXCELLENT CONDITION



... the part number on the plug is E11808



Any suggestions (unless i starts with 'shove it up your') are appreciated.

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
      
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.
