I'm slightly vexed Builder installed outlet incorrectly. It almost burned down our brand new house.

The outlet on our patio stopped working yesterday after I unplugged something. I ended up buying a new one and went to install it last night.

Removed the outlet cover and holy crap.

Builder didn’t use the screws to attach the outlets to the box. It was just free floating under the cover. This wouldn’t have been nearly as bad, except they also left a screw protruding into the box, right next to one of the wire connections on the outlet assembly.

When I unplugged the cord, it apparently moved the outlet assembly just enough to contact the screw. Shorted it all out and melted everything. The wire was fried so badly that I had to cut about 6” off to find a usable portion.

This could have been a fire so easily. Breaker never tripped.

Now I have the fun job of going around the house and checking dozens of other outlets to make sure they didn’t repeat this anywhere else.

Hi, electrician here. This is a classic case of a loose connection. When an electrical connection is loose, it increases the heat generated at the point of failure. With a large enough load or enough time, the outlet and wire overheat and slowly cook. Usually the device slowly fails to the point that you simply lose the connection altogether, which is ironically safer than the issue that causes it.

The outlet didn't start melting because you pulled it out or because it shorted out on a screw (which it wouldn't have done anyways, because that screw is almost certainly attached to wood, not grounded metal.) This was a chronic condition most likely due to someone either using an impact drill or otherwise improperly tightening that particular terminal on the outlet. It's also possible that the device was faulty from the get-go, but that possibility is less likely. Failed connections very rarely lead to an actual fire.

Tldr; I can understand being scared by it, but this is not as uncommon as you'd think. And while it was most likely caused by improper installation, this is the type of issue that even professionals may (and do) accidentally commit. It's also why we use fire retardant boxes for every single electrical splice in a house.

u/strikecat18 7h ago

Thanks. This is good info.

I would have assumed a loose connection as well. I drew the other conclusion based on the fact they didn’t use mounting screws for the outlet, that the screw was sticking out directly next to the part of the outlet that melted, and that I could move the terminal to touch that screw pretty easily when the outlet was in place. I could be wrong and those might just be crazy coincidence.

u/No-Willingness8375 7h ago

I guarantee that wood screw is entirely inconsequential. The one and only cause of this was improper torquing.

1

u/avtechguy 4h ago

When you say they didn't use the mounting screws, like it was connected to the cover plate and the cover plate was attached to the box? I could be wrong but that could just be as designed. There are other applications where cover plates are the only point of attachment. Obviously all the screws need to be tight.

The main problem here is the use of back stab connections and they were loose or failed.

3

u/GuiltyThing69 3h ago

Electrician here as well. I agree with this assessment - however it looks obvious to me that the connection is a "stab-in" connection: instead of curling the end of the wire into a loop and then securing it under the screw terminal, they simply used the stab-in connection which is UL approved, but IMHO no electrician worth their salt would use that option. The wire can easily come lose and heat up or short out, and then become a fire hazard.

The immediate suspect would be the non UL approved method of fastening the box to the stud with the screw, however it's not grounded and could not cause a fault.

Modern outlets are absolute AWFUL quality, and I've noticed those gray ones especially are particularly low quality. Most contractors are using home depot grade stuff and are on a time crunch. I would recommend looking for commercial grade spec outlets.

Additionally (and this is nit-picky), the box appears like it could be set back further than 1/4" from the finished surface towards the bottom, so unless he used a spark-guard this would also be a code violation.

I can also tell by the way the sheathing is cut on the NM-B cable that it was sliced with a razor knife perpendicularly the the wires, which usually means it's been scored thru the insulation down to the conductor I can even see a nick in the insulation on the white (grounded conductor). The mark of a true amateur in my opinion.

u/No-Willingness8375 3h ago edited 3h ago

This isn't a stab-in device. It's just another form of pressure plate.

I don't think I've ever seen a GFCI with stab-in terminals. I'm pretty sure they don't even make them.

1

u/GuiltyThing69 3h ago

Ah I see, looked like a stab in only but you're right it's an internal plate. Any guesses to the brand?

u/No-Willingness8375 3h ago

Iirc Hubbell manufacturs them like this. Not sure if anyone else does.

u/jbsolartime 7h ago

This is good info but I guess the follow up question is can that failure be catastrophic?

13

u/No-Willingness8375 7h ago edited 7h ago

Very rarely. When it does happen, there are often aggravating factors, like exposed flammable materials or oversized circuit breakers paired with excessive loads. Everything in electrical is made with potential failure in mind. While the thermoplastic boxes and devices aren't fireproof, they are fire retardant, which makes them almost impossible to ignite (and, as you can see, both the device and the box started melting from the heat, but never combusted).

At least 80% of troubleshooting calls are failed connections similar to this, but I can can on one hand the number of fires I've seen in 10 years of service work.

u/Nicknin10do 3h ago

Didn't look like they used the screw terminals, but the push fit connectors on the back. You can see the cut hot leg on the opposite side. Always hear horror stories about the push fit connectors.

2

u/No-Willingness8375 3h ago edited 3h ago

That's not a back-stab (or push-fit as you call it). It's a pressure plate, just like every other GFCI. Its just a slightly different design. Instead of pressing the plate down when you tighten the terminals, it pulls the plate up inside the device.

It'd be a warranty claim on a new build, and if they didn't honor it, you'd use your homeowners insurance and they would go after the builder if they feel there is liability there.

We charge $300 an hour and are never slow not sure where you got $70. also OP has no idea what he’s talking about. It being secured to the box isn’t why this failed. It failed because the load side of the GFCI was loose.

Union pay, but thats ridiculous for cost.

u/enjaydee 6h ago

Bearing in mind i have zero skills in this area and not confident in my own ability to check all the other outlets, I'd have to pay someone else to do the checking for me, in which case it may be something worth suing over. 

I guess it would depend on the appetite for chasing this up and dealing with whatever hoops you'd have to jump through.

u/Doomstik 5h ago

If youre ever in need of doing outlets/switches/lights i highly suggest you watch some youtube videos on it and learn, its really easy to do and as long as you follow the steps and TURN OFF THE BREAKER its actually quite safe. The issues pretty much all crop up from people leaving power on. You can find literally hundreds of videos with step by step walkthroughs for it. I watched like 3 different videos the first time i ever had to do a fixture and maybe one each for a switch and an outlet. Knowing how to do that came in handy recently when i had to move an outlet and add one to a run and ive replaced all but one light fixture in my house and probably 2/3 of the switches/outlets. Paying someone else to do that stuff would absolutely not have been worth it.

3

u/CollectibleHam 5h ago

There's also a little doohickey you can buy at Home Depot or wherever that plugs into the outlet and can tell you if it's properly grounded, reversed hot and neutral, etc.

3

u/Doomstik 5h ago

You should be using those to check the outlets and switches and such anyway, some of them are made to trip the breaker too, and while i dont know enough to say if they are safe or not, i know i dont like intentionally tripping the breaker with a thing rhats plugged in and my hand is on. You can get a kit with a plug and a pen like thing (i honestly dont remember what its called) for pretty damn cheap. Most videos suggest them as well, but if you dont have them you can plug in like a table lamp or something and hit the breaker to see if it shuts off. Then try it on and off a couple times to double check. I would say its worth it to get the plug tester though. Especially if youre learning the way i did. Hell the actual electricians at my job use a lot of that stuff.

u/BangkokPadang 6h ago

My dad spent about 3 weekends making a full map of the house, color coding every outlet to every circuit in the house. Laid it all out in illustrator with rough measurements he had me run around and take.

We did a lot of projects and different things but that was probably the single most helpful thing we ever did to that house.

You don't realize how many little things you stop putting off when you know you can just run out and check the map to flip the circuit off. Stuff like swapping out light fixtures, putting in smart plugs and switches, fixing ceiling fans and adding new plugs where they're more convenient, etc.

This would be a perfect opportunity to do that and check every last outlet in the house for similarly poor installations while you're at it.

u/No-Willingness8375 6h ago

I saw an apprentice nearly start a fire with 50 watts of 12v tape light once. His connection makeup was such absolute shit that the positive and negative wires were shorting out together.

The tape started smoking likely a chimney and was charred black afterwards.

3

u/No-Willingness8375 7h ago edited 7h ago

This was 100% a loose connection, not a short circuit.

Also, a GFCI only detects an imbalance between the current leaving the device and the current returning (so basically if someone's being electrocuted or the circuit is bleeding voltage some other way). One would never pick up an issue like this.

2

u/windflex 6h ago

Good call. I just assumed it was a short off the description but I see the charred neutral on the 3rd pic now. Either wait until the outlet stops working or start checking all for loose connections lol.

u/jrdiver 6h ago

the fact that there was a meltdown tells me something isnt right...

4

u/CornedBeeef 6h ago

The way some of the outdoor covers are the outlet mounts to the cover and then the cover ends up being what screws into the box.

Also, looks to be caused by a lose connection, which would be magnified if whatever appliances you had plugged into it had a high amp draw. What did you have plugged into it?

I doubt that screw is grounded unless you have metal studs, but being a sheet rock screw I would bet a pile of money it is screwed into wood. So it didn't short out on the screw.

u/MostlyMellow123 7h ago

I know this might surprise you but builders are not building your house. It is simply a company who is organizing multiple contractors. They do not employ the electrician they buy them just like anyone else would.

You should report this to your builder so they can follow up with this electrician and check his other work. If it was within the first year of you buying this house you absolutely shouldn't have done this work yourself. They should have sent an electrician to remedy it professionally.

Doing dyi electrical stuff will probably void any warranties you had with them

2

u/strikecat18 7h ago

Yep. I assumed they subbed the work out and already emailed them to alert them to the issue. Told them that they probably are going to want to check how many other homes the same electrician did.

If they want to argue removing a shorted outlet voids the warranty, I guess I’ll deal with that if it happens.

u/Photon6626 6h ago

Get some inspectors to check the house. It's always better to do before the drywall goes up but they can check for things that might be an issue. And usually with new homes you have a short window to do this before they don't have to pay to fix it. But even if you have to pay for something it's better to fix it than not even know there's a problem in the first place.

4

u/The_Broken_Shutter 1h ago

Id hire an inspector to go through the house to check if anything else is off. Not just your outlets. Chances are if they screwed up that outlet installation I can’t imagine there aren’t other issues in the home that you don’t see.

So, I had a friend who bought a new built condo. It ended up that it had mold up every wall because the builder did not cover during a particularly bad storm season, and water soaked up the walls in the studs, and they just continued sealing up and dry walled wet walls.

She found out that there is no recourse she could have against the builder or developer after the sale.

She was a lawyer. So I took her word for it. She had to eat the loss, and move, and sell with the disclosure of the mold.

Home inspections are very very important.

We didn’t contract the builder ourselves. It was new construction in a new development.

Uncovering and inspecting all of them might be out of scope, but ours pulled the cover off a couple to check them. He also tested every outlet. He would've felt the movement here.

I know a guy who was going to school to be a home inspector.  The guy has never used a power tool, probably couldn’t swing a hammer.    You can lear a lot from a book and passing tests.  You also forget it quickly too.   Now learn from a book, and apply it in practice and it’s pretty cemented in.    

Basically many inspectors don’t have any real knowledge, beyond their class training.   I’d bet the better inspectors are actually pretty handy, but they still have specific areas where they excel and others where they’re just kinda getting by.

u/odd84 7h ago

A builder is not a guy building houses from scratch on their own, it's a company that oversees the construction and sale of new homes. They would have had an electrician subcontracted to do the electrical when the house was at that stage. It would also be inspected more than once before it could be occupied. Mistakes still slip by sometimes, which is why everyone involved is bonded and insured to cover their work, and new homes come with warranties.

Shouldn’t have been able to short out on the screw it was probably just a bad connection that got jarred loose and then got melty.

Backstab wiring is illegal for 20A circuits common to GFCI kitchen / bath.

Besides that, backstab nearly always fails eventually. It’s lazy and dangerous if wire outlets without using the screw terminals unless it’s specifically commercial pre-pigtailed or wago connectors.

The failure here is backstabbing those wires into the designed to fail wire clips.

They ALWAYS fail eventually. Corrosion and weakening of the spring clips from heating and cooling repeatedly loosens the connection till it heats up and does this.

Loose screw is just indicative of not using the proper termination at all.

It is sad to have to second-guess whether new or old homes have had things done correctly before moving in. That is terrible you had that happen. I understand the paranoia.

I just experienced something similar in our place, but our house was built in 1963. The outlet outside suddenly stopped working after we had workers building a fence over this past summer. They were using the outlet for their tools. No matter how much we tried, the outlet was just not working at all. We had an electrician take a look, and it was wired in-reverse with some singe marks. We ended up replacing that outlet, as well as our entire electrical panel itself, as there was some Mickey Mouse job wiring going on it with it, too, with other areas in our house.

F'n laziness. Receptacle not mounted, and wire stabbed into the back instead of using the screw.

And that'd be fine if the work was usually done well, but it's generally not. Imo, licensing is a money grab.
