Strange Gfi

OK, I'm an electrical dummy ...



I have finished basement w/a bathroom. We have an ejector pump off the bathroom that has been plugged into an outlet w/gfi since I've owned the house (10 years). There is also a booster fan for my electric dryer plugged into the outlet (has been the same for 10 years).  The only thing that has ever tripped up that outlet is using a hair buzzer in another outlet within the bathroom (but once you hit the reset its fine).

   

  This morning I realize the ejector pump was not sucking down the water from the drains. I looked at the outlet and realized it needed to be reset. When I reset it, the pump would run for a few seconds and the outlet would trip up again. Tried this a few times. Thought maybe it was an issue w/the outlet altogether. Neighbor suggested maybe it was an issue with the pump. Went thru various scenarios and bottom line is when I plug the pump into other outlets it works totally fine and once I do that and reset the outlet it was on, the booster fan works fine and the outlet does not trip. So, basically this outlet is tripping when the pump is on it but the pump is not tripping other outlets and the outlet works fine as long as the pump is not on it.

   

  What could be causing this? Why would an outlet that housed the two things on it all of a sudden continue to trip when the pump is on it but the pump is fine on its own in another outlet and the outlet is fine on its own w/o the pump?
      

I am in the process of installing a submerisble pump into my well, but I have a few questions I'd like answered first.



The pump is a 1HP, 230V pump with 8.2amps and KW 0.75.  It is rated at 12/2 w/ ground. 



1) Is there any reason I shouldn't install a 230v wall mounted switch to turn this on/off if I want to kill the power.  For now a pump start will control it for my irrigation system, this would just be in addition if I ever wanted to shut things down and not have to rely on using the breaker, which I understand shouldn't be used as a switch.



2) What about installing this on a plug, so that I can plug it into a receptacle vs. hardwired.  (*I'll explain my reason later)



3) My understanding is 12gauge wire is rated for 20amp, but it looks like the owners manual calls for a 25amp fuse.  Should I use 20amp or 25amp?



*The reason I ask about the switch and the plug is because I plan on using some wiring that is already in place.  I already have 12/2 w/ground installed in the location of the pump start.  It is currently wired for 110v as it was placed there for a 3/4hp jet pump I planned on installing, but ended up going with a cased well instead, so I figure why not utilize the existing wire, but switch it to 220 instead of 110.  Basically, swap the 20amp 110v switch out for a similar rated 230v switch and replace the receptacle with a 230v receptacle and just plug this pump in. 



I question the use of the plug because I thought I had read somewhere it was ok to use one, but when unpacking the pump last night, I thought I read never to install it on a plug, so now I'm unsure.  Why would they not want it on a plug?  I guess it's not a big deal as I can always run wire into the j-box, but I hate using pigtails if I don't have to.



Thanks for any info on this...heading to the parts store in a while to grab the fuse and anything else I need.
      

My house has 240v outlet from the previous owner for a kiln of some sort. Im putting a tanning bed in its place. The plug on the tanning bed is a L6-30. I checked specs on the tanning bed and it requires a L6-30 recepticle and a 30amp circuit breaker. I went to the local home fixit store and found the correct recepticle and bought a 2-pole Siemens 30a circuit breaker. After shutting off the main breaker and using testing equipment I pulled out the 50a breaker and replaced it with the 30a..no problem. Heres where Im not sure....The L6-30 recepticle that goes in the wall has a X and a Y and a G marking on it. The G is grounding per instructions, w is white or grey, and X,Y,Z are black, red, blue or etc etc.The wires that come out of the house are red, black and a bare aluminum bradied type wire. Looking at the back from the top counterclockwise  I hooked up the red, then black, then the bare nraided to the G (has green screw) Is the black and red correct? And why doesnt it say red, black and gound?  Can anyone shed some light on this? Thanks!!!
      

I'm new to this site.  But would appreciate some troubleshooting.  I just renovated my kitchen, gutted and all, finished in the Fall.  I did not replace wiring to the dryer, nor tamper with it, to my knowledge.  We did have an electrician add a small fuse panel.  We did not add more appliances then before, added some lights, but mostly used the room to separate things out.  Had a mentor do the wiring, many years of experience, very tidy and careful work, though not electrician by trade.  We have a standard 200 amp box as far as i know.  The house is 100 years old, but the wiring isn't.



In October my mother in law heard a very loud bang.  The electric dryer had been running.  She smelled smoke.  At the dryer receptacle was molten plastic sprayed onto the wall, caused by overheating at that point, due to I don't know what.  I thought maybe I had knocked something loose in the receptacle when i was drywalling around it.  I can't remember now if the breaker had tripped.  The receptacle and plug were toast. 



I replaced the receptacle, I replaced the dryer cord, not the breaker.   The dryer worked fine until february, when it stopped heating.  I found a bad thermal fuse and replaced it, the very common two pronged white one. 



The dryer worked fine until early April when it stopped heating again.  I checked all the fuses/thermostats on the back and the heating element, as I had done the first time.  Nothing was bad.  I checked the voltage coming out of the wall, as I had done the first time, only this time I did it correctly and got a reading that told me to check the breaker in the panel, which had not thrown.  When I checked the voltage between the Nuetral Bus and the two terminals on the Dryer's 30 amp breaker I only got a good reading on one of them, telling me that the breaker was bad.  While at the box, i noticed that to the main breaker, from where the conduit comes into the box from outside, the nuetral wires are bare all the way up, no insulation, and at the terminal of the main breaker they appear to have all melted together, even a couple small pieces have melted off of the "bundle." 



Switched the range 50 amp breaker with the dryer, dryer worked fine, nothing was back fed either.  Bought a new 30 amp breaker for the dryer and installed it on Saturday.  Also on Saturday we were given a dryer, about 4 years old, same as ours, so i hooked it up and saved ours for a spare, which I deemed still good since it seemed the breaker was the issue.  New Dryer worked fine from saturday until today.  Now it won't turn on, though it didn't cut out mid load yesterday either.  The breaker did not trip.  I repeat, no tripped breaker.  I just checked the voltage at the wall and it seems to have that same problem where one side of the receptacle gets a reading of 120, and the other a reading of about 5.  The problem must be bigger than the breaker.  I am not an electrician, I am a welder.  I have gone as far as I could on my own.  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 have a home that I only use from time to time.  At Christmas one of the GFCI outlets kept tripping.  This outlet has a TV/reciever/cable box/xbox/lights, etc. on the load side.  When I reset it, everything would be OK for 20 minutes or so, then it would trip.  I did not have time to investigate the problem so I just left it.  When I returned a week or so ago, the outlet was tripped and would not reset.  As soon as I pushed the reset button in, it would pop back out.  I replace the GFCI outlet but that did not help.  I removed all load outlets and inspected them.  Everything looked OK.  Anyone have an idea.  The strange thing to me is that the problem seemed to get worse over time.  (I.e. it stayed reset for 30 minutes at Christmas and now it will not reset at all).  Ideas?  Thanks in advance.
      

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.
      

I have an outdoor light fixture that I am trying to replace.  The house was built ten years ago.



When I removed the original lamp, I noticed one of the two leads was wired to the ground, and one was wired to the black wire, which is hot per my current sensor.  There are three wires in the box - black, ground (bare copper), and white or neutral, all from a single romex cable.  Unfortunately, I do not recall where the white was when I removed the original. 



I wired the new lamp per the instructions, something I have done many times before - black to black, white to white, and bare copper ground to ground.  Nothing.  The lamp and bulbs are brand new, and I have tried four separate bulbs.  I checked the black and neutral with my current sensor and with the switch on and the lamp installed this way, both show as hot. With the lamp not installed, the switch on, and the wires disconnected only the black shows as hot.  The switch is single pole, and appears to be wired correctly with a black to each screw on one side and a copper ground on the other.



Assuming the new fixture was bad, I reinstalled the old fixture correctly -  black to black, white to white, and bare copper ground to ground.  Still nothing. No light, and I confirmed the bulb is good by putting it in another lamp.   The only way to get it to light is to connect the neutral in the lamp to the bare copper ground.



I capped the wires, turned the circuit back on, and identified all the outlets, switches and fixtures on the same circuit.  I opened every one of them up (four lights and eight outlets) and found three (one switch and two fixtures in another room) where multiple commons connect.  All were properly connected.  My outlet tester shows all outlets as "correct".  I found no instances of grounds connected to commons or vice-versa.



Any ideas?  Is it proper to wire this thing the way I found it?



Thanks for any and all advice!
      

In most homes I've noticed that there is always a receptacle right next to the electrical panel and is usually the only thing on that circuit. 

Why is this?

And is there any reason you couldn't add additional items to that circuit, for instance, if you were finishing the basement?



Thanks in advance.
      

Hello!



In a house I recently bought I have a strange situation.



There is a three way switch on one side of the wall with two sets of wires coming in:



Red, Black, White

Black, White



and then one stray Black that goes to the duplex receptacle on the other side of the wall (on the OUTSIDE of the wall!  Clearly an afterthought.)



Into the receptacle goes this strange black single wire from the light switch and the usual black and white wires + ground wire.



I went to change the ugly receptacle to a decora and now it doesn't work, though I'm not 100% sure it worked before.



I've wired the new receptacle as I remember it being wired before, any idea what is wrong? 



I've attached a diagram!



Thanks in advance for any input.
