Light Switches And Outlets Stopped Working.

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?

what the fudge sticks man?



I am not a DIY'er or a handy man but I gave it a shot..



I replaced an old a$$ receptacle with a brand new one and I wired it EXACTLY the same as the old one..



I know this because I did it WIRE BY WIRE!! i.e. I took 1 wire off the old receptacle and installed it on the new one.. wire by wire..



Power works and all that.. BUT NOW the ONLY light switch in the room does not control the bottom receptacle anymore?



what gives? i don't get it.. what changed?



Previously the light switch gave power to this outlets bottom plug, so I had the lamp plugged into it and turned it on/off with the light switch..



but that doesn't work?



I even triple checked my work and still not seeing whats up?





any ideas?





oNe.





p.s.  HOW do you release the wires on these new fangled outlets? It says push spring in slot to release but I am not seeing it?  any ideas?
      
Hello all.  I'm new on the forums and new to electricial.  I bought a house recently and found some outdoor outlets that don't work.  Only one does.  I've searched the forums and found some troubleshooting steps such as reset all the GFI outlets in house, but that didn't resolve the issue.  None of the outdoor outlets are GFI (they don't have a button).  I only have one circuit breaker and I've looked around and didn't find a second one.  None of the circuit breakers are label for the outdoor outlets and they are all in the "on" position.  All the indoor outlets work fine.  What other troubleshooting steps can I do before forking out $$ for an electrician?  Thanks!
      
I am working on fixing an issue with the wiring in one of the bedrooms in my older mountain home. Though I was not present for the cause of the problem, here is what was told to me by the tennant.  he claimed that he went to turn on the light in the closet, (a 3 lamp track bar light, wired to a switch) he heard a loud pop from the light in the closet and lost power to to the room. The room has 6 recessed ceiling lights on 2 separate switches, presently only half of the lights work.There are no breakers tripped, no obvious shorts at outlets. I have opened the drywall following the wires around hoping to find a short but I have found nothing. I decided to try something, and I bridged the working switch to a dead outlet and everything turned on. I am waiting til the daytime to follow the wires outside to the breaker box, but so far no breaks or anything.. curious if anyone has any pointers.. could the pop he heard from the track lighting have killed a breaker? its about the only thing left.
      
I'm trying to fix a problem with a track light installment over the a bar I've just put in. I've done it before. never had issues. but this particular problem is driving me nuts. It just defies logic.  The electrician who actually installed the associated dimmer switches with this dining room area was called as it seems it may be a flaw with his wiring, but he's blown us off and I have to try and solve this myself.



This is how it's all set up. I've been rehabbing our home from top to bottom, and converted our old kitchen into a dining area. Within this dining area are four sets of lights, all controlled from one box containing four dimmer switches. I set up all the new wiring and installation of the lights in the ceiling, and we paid an electrician to come in, check everything out, set up the multiple switches, and connect it all to the board. It's all new copper wiring from beginning to end, as I didn't want to connect or splice in to the old aluminum wiring that was in place. All the new wiring and lights are on a dedicated 15 amp breaker. Three of the sets of lights were set up to be available from the day the electrician came around. The fourth, for the track light over the bar, was left hanging from the ceiling capped off and with the switch off, as I still had work to do installing an overhead wine rack, under which the track was going to be set.



Two days ago I finally got around to putting the track up, but after setting it in place and connecting the power up the lights wouldn't work. I took the lights out to our kitchen, where I installed another track light system some time ago, plugged one of the lights in, and it worked just fine. I then went back to the bar area and used a spare track, then a spare connector, to see if I could isolate the fault, yet neither of the items provided a solution. Now here's the weird bit - every time I tried checking the system out, I'd get 120 volts showing from the wiring and from the track when I'd test with the multimeter. But the second I'd put a light into the track, the multimeter would drop to zero on the voltage reading on either the wiring or the track. Take the light fixture back out, and the voltage would pop back up. Inserting the light was thus completing some kind of odd loop. It wasn't just one light - I double checked by grabbing working lights from the kitchen track and inserting them into the other track - the same problem would pop up. Finally, having come to the conclusion that there was nothing wrong with the track at all, I took the whole assembly over to a nearby wall outlet, used some spare electric cable to connect up to the appropriate slots - presto, the light came on! I even double checked all this by grabbing another light fixture destined for our bathroom, and tried connecting it to the wiring over the bar. Nothing. Yet as with the track light, the minute I took it over to the wall outlet and connected it, the light worked.



So everything logically points to the fact it has to be something to do with this individual circuit, right, because a) the light fixtures work when plugged into another circuit and b) the other three dimmers and lights hooked up in the same box work fine and draw power from the same wire cable/breaker combination. The only things left that I can think of is that the electrician has either wired the dimmer switch up incorrectly or that there's some kind of flaw inside the switch itself. Does this make sense?



A friend also told me to double-check to make sure that the black wire feeding power to the light was indeed the hot wire, and it is.  If I touch it with the black test lead from the multimeter and put the red one to the neutral I show 120 volts. If I keep the black test lead on the black wire and put the red test lead to the ground - I also show 120 volts.



A final point. I know I'm not overloading the circuit - not even close. With all four dimmers maxed and every light on - including the test light on the track - I'd only be drawing 8 amps on a 15 amp breaker, besides which I'm only using one set of lights while I'm working on this problem anyway. This is a dedicated circuit, so there's no additional power being drawn away by something else.



So how am I getting 120 volts from this wiring, according to my multimeter, yet it won't light up ANYTHING and keeps giving off the indication that some kind of loop or short is being created every time I actually plug a light into the track? It's got me totally stumped.



Anyone have any ideas?
      
I have two 3-way switches in my master bath that have never worked properly. The house is very old and has been worked on over the years by many different people with greatly varying levels of skill. I was finally fed up with these switches and tried to fix them. I tried to follow instructions I found online, so with the power off I disconnected all the wires from both switches, then turned the power back on and used my volt-meter to discover which wire was hot. It turned out to the a red wire at switch #1. The other two wires are white and black (and yes, there also is a ground). I connected this hot wire to the darkest screw, connected the white and black to the other two screws and tried to test for continuity at the other switch. I couldn't get a reading on any of the wires at the other end. I tried turning the power back on and testing to see which wire was now hot at the second switch. It was the white wire, so I attached that to the darkest terminal, and attached the red and black to the other two terminals. The switches don't work any better than they did before I started - that is, both switches have to be turned on for the light to come on. What is my problem here? Thank you!
      
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!
      
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.
      
I have a 1960s house with EMT throughout. 



I recently replaced 2 florecent fixtures in my basement with 4 LED lights in their own J-Boxes in the drop ceiling. I did the following:



1. Rerouted the the conduit from the light switch to the main j-box for the lights. (previously it was going directly into the fixture) 

2. Ran 4 foot whips to each jbox holding the LED (metalic 14# wires)

3. Cut the old spliced wire (that was just twisted and taped) and used a wire nut

4. Replaced the switch with a dimmer



The lights work great.  Noticebale improvement and the dimmer is excellent.



The issue is that the circuit for the kitchen is now tripping.  I told my wife its just a coincidence, but she is sure I caused it.  Its only happened 2x (1 day apart.  Nothing unusual running on the circuit, only the fridge and the gas stove which as not in use)



Can my "new" work possibly impact another circuit?   What should I check?  Any way to avoid re-doing my work?



Things I noticed / may or may not be relevant:

1. Some of the EMT is directly in contact with a copper water pipe

2. The switch / dimmer isn't grounded

3. The wires in the jbox were nasty and old.  There was corrosion on the jackets and the jbox.  Looks like some water leaked down fromt the laundy above at some point in the last 40 years.

4. At some point (months ago) when I was in the basement I touched some of the EMT and something that was plugged in I swear I feld a shock. (just listing everything I can think of).  I didn't think much of it at the time, but now my whole electrical system is suspect.

5.  The tripped circuit (fridge, MW, stove) didn't appear to be tripped.  The fridge wasn't on.  When I turned off and back on the circuit the aplliances came back to life.  Appliances less than 1 year old. 

6. The clock on the range was reset at one point but I didn't think I turned on or off the circuit.  The lights for the basement were switced off but still worked with the fridge circuit tripped.

7.  We had a huge electrical storm right before I did the work

8.  We have a "stablock" panel that the home inspector got all bent out of shape about.  Other than truning on and off breakers I have never touched it.

9.  Kitchen breaker and basement light breaker are adjacent in the box

10.  I believe kitchen and basement share the same EMT in places.

11.  I think I now have too many connectors in my j-box.  Will likely add an extension.

12.  I didn't use the red "bushing" on all my whips as I ran out of them, but I was careful with the metal sheath and really don't think any wires were cut. (besides if there was a short wouldn't my LED lights fail and that circut break?)



HELP.  I am happy to call a contractor to come in, but I don't have an electrician I trust yet and I'm scared bringing someone in before I isolate the problem a little.
      
hello

I am dealing with what seems like a strange issue with a single pole switch, and I am royally baffled even after reaching out to someone a little more knowledgeable than me.



Yesterday: Replaced with a single pole switch with an identical one that I painted (for decor reasons). Two wires were going into the old, and the same 2 wires are attached to the new one. However, the light it controls fails to come on despite light bulb being good, and outlet located 4 feet below the switch fails to operate. With voltmeter in hand I tested voltages.

At the switch: 3 wires feed into it, all whites capped together, and 2 of the 3 blacks (A,B,C) are hot with 110. A is hot and was/is connected to one of the terminals of the single pole switch. B and C (hot) are capped together with a jumper that goes to the other terminal of the single pole switch. So I am royally baffled as to why a switch would be wired with 2 hot wires going into it. I swear it has been like that since we bought the house a year ago, and the light worked fine. I simply replaced the switch with the same wiring, and now it doesnt work. I even touched both hots (A and C) independently to wire B which (using common sense) should be the load wire to the lamp, but the lamp did not come one.



Other outlets in that circuit do not work either. They get 110 to line and ground, but not across the outlet.



I hope I was clear in explaining, and I hope someone can possibly shed some light so I can resolve this.



Thank you
      
Hi all,



I have two outdoor receptacles that are wired into a junction box in the crawlspace under my house. They are actually ran into a spare bedroom's circuit...therefore not gfi protected.  There is a switch above the access (indoors) to the crawlspace that powers these outlets and also light that runs off of the junction point also.



Would I be able to replace the switch with a dead front gfci switch to get these outlets protected. Would doing this be safe and up to code?



Would I be better off undoing all of the previous owner's work and putting these on a dedicated gfci circuit?



House was built in '87 and I am in the US.
