I thought code allowed for non-gfci circuits for devices that should still operate in those conditions, specifically for things like sump pumps and refrigerators.

I believe that's the case in either the I-codes or the NEC but not the other. At least there was something screwy like that going on when I last was enforcing code. I never gave anyone poo poo for using a non-GFCI for specific purposes like that for obvious reasons.

Would the stranded wiring be OK? It made it pretty much impossible for anybody else to ground to that wiring as it seems TWC requires all of their service drops be pulled to power now.

Stranded is perfectly acceptable, and I don't know why it would prevent anyone else from using it.

Do you mean flat braided (which still wouldn't prevent anyone from using it, they just likely don't know how or have the correct parts).

Oh...so we're back to the issue is that a brain dead cable contractor is trying to do electrical work. Okie. Well, if you want it done right do it yourself or get an electrician to bond something to the ground and run it out of the meter box with a proper grommet so the short bus guy can connect to it.

Here's something to make the thread laugh/cry:

I was hoping I could get a look at the wiring setup of my new rental by going through the ceiling tiles into the tiny attic visible from the street. ...nope.



Turns out I have a real ceiling, it just looks like poo poo, so they put up a new one, six inches lower and extended the wires for the ceiling fixtures. :gonk:

That's all pretty typical, and the only problem there is that they didn't enclose the splice in the box (and didn't use enough wire to make that happen). On the scale of "dangerous electrical", that's way way down the list.

Recently got a dehumidifier (this one) and overall it works great except for one concern: the power supply gets hot. I mean stupidly, ridiculously hot.

The manufacturer's website even has a disclaimer of sorts trying to say this is normal and just make sure you're not tossing blankets on top of it or anything. Power supplies being warm to the touch is nothing unusual, but this thing is hotter than any I've ever experienced, it almost burns your hand if you hold it. I've had to keep a trivet underneath it because I'm afraid it may scorch my hardwood floor.

Is this a case of shoddy manufacturing on the power supply's part? If I find another power supply that provides the necessary voltage, would it also get so blazing hot? While I don't think this thing is going to burn the house down, I am worried it may burn out the dehumidifier after only a year or so.

That's a low budget Chinese piece of crap with known problems. Take a suggestion from the thread title and put it in the trash or return it.

You already knew this or you wouldn't be asking and keeping a trivet under it. You are correct. Don't doubt yourself.

Here's a question for you guys. Last night, the power went out in half of our apartment. Basically we lost it in the kitchen, living room, and one bedroom, while it stayed on in the bathroom, second bedroom, and study. (Also there was one outlet in the kitchen and one in the bedroom that stayed on). I went and checked the breakers, everything seemed ok, no idea what is happening. About 45 minutes later, power goes out in the rest of the house, and then everything comes back on about 15 minutes later.

Obviously I called my landlord about this because it seemed weird as hell. Today he got in touch with me and said that his electrician had checked with NSTAR, and apparently the building is hooked up to two different poles. Last night there was some sort of issue that took out one pole, and they had to turn off more stuff (including the second pole) while making repairs. Is that possible? It seems totally bizarre that one unit with a single box can be getting power from multiple poles into different circuits. How terrified should I be about the wiring in here?

I talked to NSTAR myself, and there were definitely outages in our area last night, so I don't think it's a crazy cover story he's making up (he's also been a really good landlord so I am inclined to believe him)

Sounds like you lost one phase. This should't have anything to do with "being fed from two different poles."

Ashcans posted:

The explanation I have is basically third hand (The electrician/NSTAR talked to my landlord, who called my wife, who emailed me at work) so it's very likely there was a mistranslation or terminology drop somewhere. If we lost a phase, is it something we should be concerned about and is there anything we should ask the landlord to do? He seems content that Nstar solved the issue with whatever work they were doing.

I tried to google this a little but I am way out of my depth. I just want to make sure I'm not ignoring an electrical hazard, that's all.

Nah, if everything is working again you're fine.

The way power works in the US is you get two hots and a neutral. If you connect to one hot and the neutral you get 120v. Connect to both hots and you get 240v. One side of your breaker panel has the one hot leg and the other side has the opposite hot leg. 240v breakers grab both, 120v stays on it's own side (some panels are different, but operate on the same principle).

This is GROSSLY oversimplified, but should explain how you can lose only half of your circuits.

They are significantly safer. In fact, replacing existing breakers with AFCIs and CAFCIs will show you just how bad your existing wiring may be.

We all did fine for many years with standard breakers, and before that glass fuses that often had coins jammed underneath them to keep them from blowing. If you don't care about code then you need to decide how much a one-time cost is worth it to you to prevent a fire.

Hopefully I'm in the right thread for this question.

I have a dimmable floor lamp with a separate reading light. The lamp has a single plug, that runs to a box that houses both the dimmer switch for the upright lamp and the on/off switch for the reading light. Recently, the dimmer has been failing/malfunctioning, and I'm looking for a product to replace the box - i.e., a box with a single plug with one dimmer output, and one on/off output. Can anyone recommend such a product, or let me know what other specs are needed to recommend something? My only alternative is to either take the existing box to someone who can repair it, or to use two separate plugs and wire one on/off switch to the reading light, and a second dimmer switch to the upright lamp - neither of which is particularly attractive.

If I haven't sufficiently articulated anything, please let me know. I can check the specs for the lamp tonight, if necessary. Thanks!

Pictures of the dimmer/box inside and out would probably suffice to point you in the direction of matching part(s) for replacement.

Cutler Hammer CH panels are on par with QO panels.

And the proce difference between Homeline and QO or CH *FCIs are not all that huge for your average stuff (15/20A single pole). We're talking $38 vs 50 or something. For a panel that has a copper bus bar rather than aluminum.

But, yeah.....Homeline is sufficient for a house or garage if you aren't a spergelord about these kinds of things (like I am, having just installed yet a larger QO panel in my barn, fully understanding that I need about $400 worth of breakers now).

There's a gfci outlet next to my breaker panel. The only thing plugged into it is the gas alarm. The outlet keeps tripping, most likely cause that the outlet in question has just gone south for some reason or another? Is there some way to test its goodness? I have an outlet tester that will test gfci functionality, but that'll just tell me that it'll trip, not that it's gone soft or anything.

What else stops working when that outlet trips (if any)? There can be other outlets downstream that it is protecting and something plugged into or wrong with one of those could be causing it to trip. Ot your gas alarm could be causing it to trip.

GFCI outlets are cheap enough and it's a likely enough scenario that it may just be bad that it's probably easier to swap it out (if you are comfortable doing that kind of work) and see what happens rather than trying to track down the other possibilities.

What would that outlet be for if it can't handle a standard kitchen appliance? When you find the fuse, I'd be interested to know what the rating is.

While it shouldn't be the issue, a toaster oven is probably the largest draw counter top appliance in a kitchen, and something that didn't exist when this stove was made. At that time, something that draws about 1/4 of your average toaster oven was the largest draw: a toaster.

My grandmother had a range like this in her kitchen. Super top of the line for an early-1950-whatever thing with a rotisserie and everything. The outlets had a 15 amp Buss screw-in type fuse. These things "wear out" (fatigue) with heat and vibration, so when they are on the back of a stove they like to blow pretty much constantly.

I'm assuming we're talking about an ancient range here, as I've not seen anything with an outlet on it since glass fuses were no longer a thing.

If it's something newer, the model number should be on a sticker inside the oven door and lead to an owner's manual pretty easily. If it's one of these old boat anchors, pictures would probably help.

Code question: I replaced a standard outlet in the kitchen with a tamper-proof GFCI one and it's now protected two other downstream outlets. However there are three other outlets in the kitchen. They are on the other side of the kitchen. One for the microwave/vent hood in a cabinet, one on the counter and one for the fridge. Do any of them need to be GFCI protected?

If it was code when it's installed it's still code. GFCIs aren't retroactively involved other than in some jursidictions on ownership/occupancy change. So if you've already for a C of O, you've already got a C of O.

On the other hand, if you're asking about what is smartest thing to do you'd be replacing all of those receptacle breakers (and even lighting circuit breakers) with CAFCIs. Yeah, it's expensive. Yeah, it's either current code or soon to be current code depending on where you live. GFCI protected kitchen receptacles are the bare minimum I'd be comfortable with in my own home.

Also I am going to be wiring up more garage lights and more outlets.

Lights: currently have a couple of exposed Edison lamp fixtures on a switch. I want to convert the single switch in the wall to a double switch and be able to have a fair amount of T5HO fixtures. Standard two-wide old work box. I am looking at seven or eight on the new switch, keep existing switch on the old bulbs. That's about an amp each (two 54 watt T5HO bulbs = 108 watts/110 volts) so eight amps? Assuming the wiring coming into the existing switch box has hot, neutral and ground can I split that off into two circuits? Next: I want to have the T5HO fixtures movable so I was going to use standard receptacles on the ceiling. Do they need to have GFCI protection since they could be used to power other things? Would that cause issues with fluorescents?

Well.....you can tap what's in there if it has sufficient amp capacity based on the length of cabe and it's size. Maybe that's fine, but if it's a long run of contractor grade 14 wire I sure wouldn't do it.

As far as GFCI, it's an unfinished storage enclosure so yeah....all outlets regardless of location or purpose need to be GFCI.

Outlets: previous owners added five outlets to the garage on a new circuit. Need to actually read the cable but looking in the garage attic it was orange and big: 10 gauge?

Yes...in "new cable" orange is 10. Yellow is 12.

As for issues adding another outlet to the run, that entirely depends on how long it is already, how much longer you want to make it, and what size the breaker is. Chances are good assuming normal home and garage dimensions and a 15 or 20 A breaker that you are A-OK.

Based on most CURRENT codes you need to use wire nuts or other mechanical attachment devices ACCORDING TO THEIR LISTING. None of them list "solder" as being acceptable under them.

But old school codes? Most of them said solder was acceptable AFTER good mechanical and electrical connection.

So, properly soldered=safe but not to code, most likely.

Yes, you want the second type.

You can put a box above/near it in the ceiling and feed it from there with a short piece of MC. Realistically, that's not even needed since it's all above the drywall, but it's not a bad idea just incase something goes screwy and the tracks get pulled down.

The issue with that is I don't have access to the rafters from the attic at the peak, I could do it from the bottom, but also worried how to extend the box so it reaches to the bottom of the 6 inch "beam"

Cut drywall and patch it. It beats having the chandler fall down.

And if this is any kind of "normal" chandelier ist's on threaded pipe that should be plenty long. You put an escutcheon where it meets the finished ceiling.

If it's too heavy for the lid of a box use a chandelier brace (installs across rafters, accepts threaded rod, some are adjustable to make it easy to hang the fixture straight down on a sloped ceiling). You'll still need a box for the connections and you'll still need to cut drywall. Actually, if you're trying to get this to come through those decorative beams you will probably have to use a chandelier brace and hang it high. You may ot may not have the access you need to do that in a way that allows you to cut the drywall so you can patch it without removing the beam/trim stuff.

Bottom line: there is not likely going to be any way to do this properly without cutting at least drywall if you don't have access from above.

That depends on how much drywall work. The first coat of drywall mud takes a day to dry by itself. You can probably get the second and third coat with all the sanding done the next day though.

I've started using the setting-type 20 minute drywall compound for patches, not the premix buckets that have to dry. You can go over your first coat in an hour or less with this stuff, and be sanding the final coat in 30 minutes or so if you run it dry enough. If you run it too wet it will have to dry out after curing, pretty much defeating the purpose.

Just be aware that once it starts to set it's off to the races. It cures rather than dries, so it all happens astonishingly fast once the process starts. I never mix more than a single tray at a time.

What's the draw on the fireplace? It probably shouldn't be going through an outlet. It might even need bigger wire to begin with.

But if the wire is the appropriate gauge for the length/draw I'd suggest a simple solution that itsn't really something you'll find in a code book: Take the outlet out of the circuit and put it in through a tap. As in, take both sides of that run that is currently coing through the outlet and wire nut them directly together along with a short piece of romex. Attach this short piece of romex to the outlet so the current is no longer going "through" the outlet to the fireplace.

This is not the right way to do it. If I were you I would run a dedicated circuit the the fireplace and stop screwing around. But I would do as I suggested until I had the time to do it right.

It's called a "gimbal" and yes, you can absolutely get them as LED retrofits that are gimbals.

Help me understand how/why there is a gap? The LED retrofit kits I'm most familiar with are friction fit, so unless your can depth is too low you should be fine. And if your can depth is too low and it's a standard-ish can like a Halo you should be able to move the backplate (what the incandescent bulb used to be screwed to) up a bit. It's adjustable for various bulb/trim ring combinations.

My first reaction to this would be to open it up and check out what's going on with the outlet. Are the connections still tight? If everything looks good, toss another $0.88 outlet in there and see how it goes.

My second reaction would be to look at this and say "self, if I know how to wire an outlet and there is one close enough to plug in this extension cord why don't I just bang a box in for real and wire it in to the existing outlet."
