Forgot about this thread and posted in the Fix it Fast thread. Cross-post + new question. Some updates since the last post. Just bought the house, built in 1947. Kitchen was remodeled but no GFCI's installed. I bought a 3 pack but that is a project for another post. Replacing a incandescent dimmer switch: It all fit when I took it apart. LED compatible dimmer installed to hopefully remove flicker. It worked, one isolated light still flickers. I think I'm just going to take out the bulb for now until I can work up the willpower to hire an electrician to crawl in the attic. We know from the inspection it's missing the cover on the box. Replacing a incandescent dimmer switch which was hooked up to a fan (thanks!) with a light switch. Is it possible to add a grounding wire while I have it open or is that a silly idea because what would it even ground to? Update: Switch installed, fan struggling noises and LED light flicker are gone. Turns out there are 2 outlets, 8 recessed halogens, an outside porch light, 3 fans w/ quad lights, and 5 other misc light fixtures on this 15A breaker. It spans all 3 bedrooms, the living/dining room, and the laundry room. All bulbs have been replaced with LEDs now (see first dimmer switch.) I haven' tested any other outlets yet for fear of finding more things hooked up. Same circuit, wanted to flip a light switch so up was on. Please tell me this isn't just cloth insulated wire: This room also has the last 2-prong in the house. I see from the original post that I should throw a GFCI in there, I will do that soon.

kid sinister posted:Don't forget your tamper resistant GFCIs in the kitchen. Awesome, thanks. I have a 3-pack of tamper resistant leviton 'smartlockpro' gfci's I originally bought for the kitchen. Might need more, depends on the mysteries behind the face plates in the kitchen. Now, one is going in the 2-prong and one in the back room behind the garage to plug the mower in (something something don't kill yourself when you run over the extension cord.) I will read the 2->3 prong conversion thread. The outside porch light on Ye Olde Longass Circuit flickers and dies. Removed the bulb and disassembled it, there is certainly a ground wire doing what they do best: Hanging out not connected to anything. Put it back together sans bulb because I didn't have the right tools to repair it at that very moment. The woven cloth is on some kind of rubber looking/feeling substance. Is there anything to be concerned with there? I know both fiber and rubber degrade over time. I'm going to assume it's original to the house putting it at 68 years old. Thanks for the tip on the tape, we do have hardwood.

TooMuchAbstraction posted:You should only need one GFCI outlet per circuit, since it detects ground faults on the entire circuit, not just for things that are plugged into it. You may overestimate how much circuit tracing I want to do, unless this it's out of code for me to add them excessively? (All accessible.) I haven't mapped my entire breaker box yet, so I don't know if I have 1 or 2 breakers covering the kitchen.

ausgezeichnet posted:I've gotten 25 years of use out of this book and it's updates. It's worth way more than the $10.50 it costs on Amazon. If you use this to build understanding, you can refer to the NEC for data on conductor size, box fill, etc. Thanks for this, I just bought it to have as a easy reference. Also I saw a month or so back in the thread low voltage cat5e vs cat6: cat5 (and 5e) is absolutely rated at 1000 mbps full duplex for 100 meters (not feet.) The 5e spec only improves crosstalk reduction for noisy environments. This is more important in commercial installations with large fluorescent ballasts than at home. Cat 6 provides further reduction in cross talk and adds 10gig capability for the same 100 meters, with 6a bringing us to 500MHz and even more crosstalk reduction. Assuming your home is a normal home you can rig the jankiest looking cat5 cable for 100 feet (<1/3 the spec) and likely still get 1gbps performance out of it. If you are running it through your CFLs as a way of supporting it and it goes around your microwave several times by way of a service loop you should consider Cat7 STP.

I haven't mapped my entire breaker box yet, so I don't know if I have 1 or 2 breakers covering the kitchen. "Wiring Simplified" came in, looks like good reading material. I re-read our inspection report. Looks like I have nothing to worry about with the 2-pronger because none of our 3-prong outlets have ground either. I walked the house today with one of those 3-light outlet testers and confirmed, plus found a hot/neutral flipped one. The GFCI in the first bathroom tests good both with the plugin tester and both outlets turn off if I press the test button. The second bathroom has a single gang non-gfci switch/outlet. This just became way more than I had hoped. Our lights in the ceiling still have the occasional generalized flicker where they all do it at once, plus 2/8 of them aggressively flicker and have now died. I don't know if it's a bulb thing or what at this point. Same circuit our porch light is on which also flickers and dies. Is this something our "home warranty" should cover? Is this a "it depends" sort of scenario? I assume the demarcation of "Fixtures" vs. the rest is the little wires that stub out from the fixture to splice onto? "Electrical System/Doorbell/Smoke Detectors Covered: All parts and components that affect operation. Not Covered: Fixtures - alarms/intercoms and circuits - inadequate wiring capacity - power failure or surge - low voltage wiring - direct current (D.C.) wiring or components - lights."

After many funny stories later, we think we're getting our dishwasher plumbed in today. The outlet under the sink where it would plug in isn't configured correctly to be switched+always-hot.

I'm going to tape this inside of my currently unlabeled panel, any suggestions? I have the address and date at the top. It's printed on a laser printer so dampness won't cause it to run. We had a dishwasher installed and I became curious if there were any hilarious caveats to running it (toaster+microwave+electric kettle+refrigerator startup+dishwasher+coffee machine would = sadness.) Draws 1150watts when the heating element is on, 10-30watts otherwise, 1kwh per "normal" cycle so says my kill-a-watt.

I took a high resolution picture of the panel. I don't know which model panel this is, or how important it would be to finding the correct parts. Googling seems to indicate fillers are typically for a list of models like: " Zinsco- Q,QB,QB24,R38,RC38". I will run by Lowes and try to buy one. Is installation as easy as taking off the cover, popping it into said cover, replacing cover?

bEatmstrJ posted:The part I don't really understand is the permanent vs non-permanent installation and using lamp cord instead of romex. To me it seems like its way safer to do it the way I'm doing it since I'm using proper boxes and romex, just inside of plywood instead of inside the wall. I guess I could just use a three prong extension cord plugged into the existing wall outlet and cut off the other end and wire it into my furniture with boxes/romex so it truly is removable. Would that be more code friendly? You came to ask experts for their opinion so as not to burn your house down. Accept their advise and move on from there, it doesn't materially change the cost of your project. One of the hardest things in life is knowing when to ask those with more experience than you how to do something. One of the smartest things in life is getting past it. You're building something really kickass. If you move, a home inspector worth their salt will notice the head board is a fixture not an appliance and make you, at your own cost, undo all of the work if you're taking it with you. You're trying not to create one of those "what was the PO thinking..." moments.

Hurray our coffee maker, dishwasher, and outlet in the dining area don't work, but the breaker is closed and other things on it do work. Pulled off the cover on the left-most one and voila, the start of the chain. Or what should be a chain. Contactless tester beeps, multimeter shows me 120VAC hot to neutral on the poles. There is way too much wire in this thing for a single gang outlet. Flip off the breaker and pull the outlet and the hot wire pops off all on its own, spread it out, close the breaker and confirm, then open it again. Looks like when they installed the their-fridge-now-my-dishwasher outlet in a remodel they just "tapped" this outlet. The white romex(?) goes from this outlet "up" (no strain relief or third ground wire), then enters the dishwasher outlet from the bottom (same thing, but I can see the ground wire). Unhooked the hot and tested with continuity to what I believe verify the two black wires I'm seeing match. There is some brown that does not scrape off my with my fingernail on the romex, is that evidence of arcing? Haven't tested the balance of the "original" non-romex wiring since I think I have a smoking gun. Hot wire verification, first noticed the brown stuff on the romex in this picture: Note the two wires in the bottom of the neutral side: Just a closeup of the "hot side" where you can see the other side of the romex coming in: Straight on after fingernail cleaning the discoloration on the romex: We already have a licensed electrician coming out tomorrow because I originally thought this was rodent damage. I assume this is Not Ok and the correct solution here is to turn this into a proper daisy chain. The dishwasher outlet has nothing on the "load" pins on its outlet. The correctest solution would be to have the electrician pull a dedicated 15A breaker for the dishwasher, plugging Kid Sinister's 120V Glory Hole in our box once and for all. For the latter, would you use a (A|G)FCI breaker?

ninmeister posted:Unless I'm seeing the colors wrong, arn't the screws on the top picture (what you labeled "neutral side") gold? That would be the hot side, and silver screws are the neutral side. That white on the hot side could be being used as a hot conductor, but was never labeled with black tape properly? Or the other solution is it's just a mess. The very first picture is right after I pulled it out and before any untwisting or unscrewing of the terminals. The wire chilling out in the air was "hot" according to the tester and fell off the second the screws came undone which were holding the receptacle in place. That is the only evidence I have of "hot/neutral". The last picture I have untwisted things to get a clearer look at the various wires, so the ground pin is "up." Here is a picture, this is the only terminal I've unscrewed, the balance of them I gave a gentle tightening to make sure they weren't comically loose. The empty silver terminal is where the hot wire and the black romex were screwed on. The other side is gold.

TCP brand dimmable LEDs work great, but you also need to make sure the dimmer is compatible with them. We've had good luck with the Leviton CFL/LED dimmer replacing our normal incandescent dimmer.

One Day Fish Sale posted:On the other hand, it would amount to like $40 worth of conduit for a separate run, so maybe it's not worth it, though I was considering trenching with a sub-soiler since I have a tractor to use it with. This leaves a narrow groove 18-24" deep, which would be handy for a single run but might be tricky for spacing two runs a consistent distance apart. Code aside if you have the ground open just run a second conduit for $40. Then you don't have to deal with HV and LV stuff sharing conduit at all. Slap a small POE switch out there and you have yourself wifi, a phone, and security camera all without needing to install any further 120V+ outlets. Make sure you properly terminate the STP. It's been a long time since I looked at it but as I recall you have to make sure your switch/patchpanel connects the grounding correctly from the STP jacket + STP RJ45 connector. A single STP bulkhead and a proper grounding strap on a used 1U metal patch panel is likely the easiest and cheapest method. Outdoor rated POE cameras are had for around $120 from like Hikvision, just make sure it is the US market version.

Is there an adapter to get me from 2-pin to an outlet, or do I have to go 2-pin -> socket -> outlet? The latter sounds and would look skeevy. The 2-Pin connector is potentially not 120V AC power, but the output of a ballast to drive a fluorescent tube. What bulbs go in it? Can you read the sticker for input/output power?

They essentially want the house sold "as-is" but didn't put that in the initial listing or in the initial contract offer. Even if I have to pay for it I will insist that I want an electrician to inspect it before we proceed with purchase. Selling as-is sounds like a great way to reduce the price of sale by more than the estimated repairs. If that was literally the only thing wrong with it and it doesn't otherwise seem like a groverhaus maybe it's a bargain. Otherwise don't become emotionally invested in a death trap. Did your inspector actually test all the outlets, does their TV have working cable, crawl around in the attic, etc? Electrical panels aren't supposed to have finger holes.

It will take a little time though as taking apart that front box again and putting it back together takes a bit of time along with labeling everything; I only get like 30 actual minutes of free time this week per day with my messed up work schedule so please don't think I am being lazy. I have nothing constructive to add, other than dealing with remote troubleshooting at work has given me a keen eye for accidental pronouning of specific items, which is why I suggest the tape. Talking on the phone asking someone which port they are about to unplug and they say "this one" and point at it. We've sent them a tablet with a camera and gotomeeting installed. Now they can point all they want because we can see it. The labels guarantee neither you nor the other posters here can accidentally talk about a different wire, which will hopefully lead to net shorter troubleshooting time.

The fridge is on the same circuit, for what it's worth, so it's definitely got a bit of a load on it. I just can't figure what a gas oven is doing to be that last straw. How many watts is the microwave? You could be using 100% of the circuit just with the microwave. If it's a 1400 watt microwave that is 80% of a 15 amp 120v circuit. Combine that with the compressor on your fridge and you're in for a bad time.

We've received 2 basically identical quotes to re-wire our house, including a new 200A main panel. Kid Sinister's Glory Hole. We've left a message with a third electrician in the area. Both claim they're going to do it to NEC and handle permits with the city. Their licenses check out with the state website. The utility came and put a sticker on our wall for the new meter/panel location. I've asked them both for a sample switch, outlet, panel, and breaker model number so we can make sure they are what we want. (Wife wants Decora rocker switches, but regular outlets.) We're doing this as part of a larger project to repipe, rewire, insulate, and upgrade the bathroom exhaust fan to exhaust outside the house project. Both quotes came in at ~$8,800 for ~1250 sq ft 3bd/2ba and trenching to the garage w/ 50A subpanel. (We have 60A service today. ) Neither includes patching & paint for lathe and plaster. Anything we should be asking them about or checking? Anything we should do "while we're in there" ? We have ceiling fans in 3 rooms (2 bd + living), and light fixtures in every room already. Is there a way to pay a reasonable amount extra to somehow keep dust under control? We both have asthma, and plaster dust is low on my list of things to have coating the whole house.

kid sinister posted:There sure is: get a hotel room or stay at a friend's place. Another option would be to replace your furnace air filter with a really good one before the work happens, then consider it sacrificial. Once all the dust has settled, start cleaning. Staying with the inlaws who live 3 miles away. Already have spare ultra high filtration filters, a Dyson vacuum with a HEPA rated filter, and our ductwork is getting replaced with the insulation job. Everything else cover with plastic and pray? I'm more worried about residual dust than "in progress" dust. Should we have one of those vacuum's in a truck come by and suck every surface off and outside? 75% of our wiring is not modern romex (which I realize is the brand, NM?) It's crumbling rubber and fabric coated wire from 1947. What is romex was done by someones uncle jimmy who overfilled boxes, left them uncovered, put dimmers on the fans, and didn't use pigtails where necessary. Also most rooms have 2 outlets at most, we have a GFCI (singular) on a dogleg as it doesn't interrupt anything but itself. Garage is effectively 1 regular car or 2 ultra compacts if you use any of it for storage. The driveway is sort of an odd angle to get two cars in, I tried. A welder or car charger is very likely. (Though the welder would be for my wife and dad. He has a stable of them.) There is an extra room in the back as well. If you squint you can see exposed romex ~4' off the ground on the left. This runs into a semi-concealed (but accessible I believe, it's reachable to attach a cover with a screwdriver) jbox that doesn't have a cover and may not have anything securing the wire but I haven't look in a while. The garage is currently only attached to the house by conduit and cement. All of this is getting fixed and a city inspector will see it. (Picture was from the day I got the keys to the house a year ago. There is now more... stuff. Note all that paint with legible paint codes!) I take it go up to 100A / higher gauge wire? Run length main to sub is ~50' but I haven't measured it. Roughly double that to reach the furthest corner or the room behind the garage from the subpanel via the walls. Oh and our meter is handily 7' off the ground. The handy pamphlet SCE gave us and meter spot sticker both say that 4'0" to 6'3" to center is code. To my knowledge they are, but that's why I'm asking for sample models. I will double check. As I've understood it from this thread AFCI breakers, GFCI outlets in wet areas/garage. I want exactly 0 punch list items from our inspector when this is done.
