I’m using Caseta dimmers without temperature control for my lights, so nothing I can directly recommend. I’m sure there’s a home automation thread or esphome reddit sub where they can give a heads up about sales on easy to flash lights. After doing a bit of googling, it does look like it’s a bit annoying to try to locate compatible ones and flash them (if you’re not into electronics), so hopefully I didn’t get your hopes up for nothing. If you’re ok with zigbee, Ikea bulbs are standard and can be used without their hub.

I did ask on the r/homeautomation subreddit and they were uniformly useless. Afaict if you're unwilling to use google home or alexa about 95% of the sub is straight out.

At this point I've basically resolved to just use Home Assistant and I've been using their forums to guide purchasing decisions. I bought a Home Assistant Green after messing with an install on a lovely computer. Then, through the HA forums I found some lights that people were able to finagle into working for <$1 apiece as long as you bought a pack of 20 from the wholesaler. So I've plunked down a couple bucks on all that and I'm pretty sure I can get what I want going that way. I'll be back for a trip report one way or another.

Ehhhhhh. RJ-11 jacks are usually just CAT3 cable. So you're only getting three pair. If you're just looking to run basic analogue signals over POTS lines, it might work. But if you're looking for any sort of bandwidth above that, you'll need to rip those out anyway for some CAT5 or better.

Phone wiring is typically daisy chained around a house from jack to jack. Ethernet needs to be home runs. There's little that phone jacks are likely to "help" other than already having a hole in the wall - potentially with a low volt ring but even more likely with a full bax that's going to to be in the way.

4 pair CAT3 exists. Best it can do is 10 Mbit though.

the hole in the wall (and the baseboards) is really the only thing i'm hoping to get out of them so that's basically right in my mind. really the overall goal of the initial exploration is to pop off the RJ-11 jack and see if there are existing holes down to the first floor that we could use. in an ideal world it already goes downstairs somehow and we just throw an ethernet cable right alongside the telephone cable. in a terrible one i gently caress everything up and somehow break either the RJ-11 outlet or the telephone cable, at which point i quietly replace the faceplate and never speak of it again. i never intend to use a land-line telephone and most likely whoever buys the house from me won't either because even as forgotten and obsolete technology it still manages to engender more harassment and interruptions than cell phones. so on the whole there's relatively little to lose.

just to be clear in the case where i do use the same holes, i would be running plain old gigabit ethernet cable/cat6. i'd just feed it the extra 3 feet to one side so i could make an entirely new outlet near the telephone jack. all this is assuming a LOT of course so how far i go with this plan depends on what i see when i peer past the RJ-11 jack; if it looks awful there's definitely always the option of replacing the faceplate without really touching anything.

I was helping my brother out at his house with some hosed up wiring and when I popped open his GE panel I saw this, among other things.

Was this to code back in the late 70's?


I should also mention the stuff I was there to fix. A PO had previously build out some lovely closet in the garage which was taking up a large amount of space and not useful at all, so he wanted to rip it out. It's purely superficial walls came down easily, except the PO had also added some wiring over the years and instead of running it up the wall cavity with the panel, had just kind of strung it loosely around the inside of the closet and then stabbed holes in the ceiling to run it up into the attic and to the rest of the house. Wiring must have been cheap back in the day because the majority of it was 10 gauge. Including a huge strand of 10/3 being used for a single 120v 20amp circuit. It's also worth pointing out that they used the wrong brand of breaker for this circuit, and instead of actually screwing the 10 gauge conductor into the breaker, they just wedged it between the screw and the housing of the breaker :stare:


I wish I had thought to get a picture of the one junction box where 5 different 10 gauge wires were nutted together. I don't think box fill was ever a concern for the PO.

I ran the circuits through the wall cavity properly, and set him up with proper breakers that are AFCI/GFCI protected. The mystery 10/3 wire circuit keeps tripping the GFCI. I followed it to a floating junction box deep within the attic that has 4 more wires coming out of it, but I couldn't get to it without building out a crawl way. I suspect the neutrals are crossed with another circuit, and the GFCI doesn't like that. We didn't have time to do all that so we're just going to leave it off, but we don't know what it powers, so we went to every outlet, light, and appliance we could find and tested them and nothing seems to be off. So god knows what that junction box is even doing.

First picture seems fine to me, other than some lazy pushing wires through too far on the neutral bar.


This, however, terrifies me. Like, not as an issue today, but at some unspecified time in the future. There's a possibility that the breaker is approved for use in the panel. I don't know for sure, but investigation may prove that it's a valid installation. I have hesitations given the spacing between the add-on new breaker and the older existing ones.

My real issue is that wire termination. Looks like poor contact that works for now, but if that circuit is ever stressed, that connection is probably getting worse and a ticket to Fire Town. I think the wire is sitting on top of the cage clamp it's supposed to be resting inside? It's hard to tell from the one picture. Luckily, this should be solvable in a minute or two with a screwdriver and some appropriate caution.

That's "fine". I don't know if it was to code and under what code, but it's very common. Spend $6 on a new ground bar and re-wire if it bothers you. I wouldn't unless I was doing extensive amounts of other work in the panel.

That was my thinking. Everything was nice and tight and it's obviously been fine for 50+ years so I didn't touch that at all. Just curious if that was code/common back in the day.

It definitely was very common in the days of rag wire insulation and the little 18 or 20 gauge undersized ground conductors. After that too, because I've seen a lof of fuse panel to breaker panel replacements done that way.

This is a basic switch loop:


Here's something like what I think is going on in your box:


Where do the two unconnected wires go, are they a pair that leave the box in the same sheathing?

You'll need the multimeter to determine which pair is supplying the power.

Right, so took me a while to figure out the multimeter and find time to play with what I now know is called the "ceiling rose". Thanks to this video, I was able to establish which pair is in continuity when the light switch is flipped on. But just bundling those together still leaves all the sockets in the room and adjoining room without power.

What's the next step? Should I flip the breaker on and figure out which wires are supplying power?

We recently got a house to stash my mom that was built in 1961 . . . right before ground was required. So it has a fuse box and no ground. It's using nylon-braided wiring. Some of the fuses are 30A. I'm not on-site there right now so I wasn't able to verify the circuits that were fused with 30A, but I have bad feeling they're 20A circuits that got the 30A fuse treatment. I think the rule of thumb there is to doubt the integrity of any wiring "upgraded" like that.

We went in with a notion of completely rewiring in the first place and thought we adjusted ourselves accordingly, but all the quotes are coming up wild. Well, it's more like I don't think we understood post-Covid pricing for anything and they're coming in normal. So we're torn on doing it anyways. We're suspecting it'll come back in the resale since the house was sitting for a long time on the market (presumably because of this and something that the inspector missed that's going to turn into a war).

A major problem with rewiring is that the roof angle is really acute, so it's very much a crawl-on-your-belly affair. Most of the rest is accessible from underneath in the basement, but some of it is in a crawl space instead.

We're considering some alternatives (in order of severity):
1. Apparently there are retrofits for fuses to convert them to breakers? We just do that and call it a day.
2. We install a new panel and put in GFCI breakers. Presumably, we later can work off of this to add or modify circuits.
3. Some or all of the circuits get replaced with Romex with a ground up to their receptacles. Anything in the ceiling runs without a ground. I think this would be DIY since I'm not sure an electrician could/would do it. That's probably a hint to its suitability.
4. Anything beyond that is going into a full rewire.

We were also getting quotes assuming drywall was mostly retained, and we're now reviewing what would happen if we got into different levels of drywall busting.

Is there anything else we should be considering?

You found the two wires that go down to the switch. the power and the switch leg. In the ceiling those two should not be tied together. One of those is tied to the power from the panel's breaker and the switch leg connects to your light.

I'm seeing sheathing around every set of two wires in your photos so we can presume there's no ground wires. Four sets in total, one set go to the switch, one from the panel, one to a receptacle in the next room. You have to find out what that fourth set goes to.

Knowing which wires are from the panel's breaker will be useful to prevent damage to equipment. You mentioned there's only one breaker off right now:
If all the wires are disconnected you can check in voltage mode with your multimeter between every combination of wires with the breaker off.
If there is a wire that has a difference of about 230v with the breaker off then there's a second breaker in the on position. Meaning, there could be damage to equipment and further troubleshooting is needed.
If there is a difference of 0v then there is only one breaker powering the lights and receptacles which is probably what's happened here.

I'm seeing this picture again and seeing the two possible neutrals disconnected here.

If there really is just one breaker in this situation then go back to this situation and connect the two common neutrals together to complete the circuit

A panel swap would be the safest option. You can buy a circuit breaker tracer and map the layout of your home to identify how many receptacles and/or lights are on each breaker. Our NEC recommends no more than 8 receptacles per breaker on 15amp breaker and 10 receptacles on 20 amp breaker. Your breaker size will be limited to the existing wire guage. 14g will be for a 15A breaker and 12g will be for 20A breaker.

AFCI breakers can be supplied to the bedroom receptacles. My local teaches us to have no more than 5 devices on a GFCI load side if you want to save money on new devices. Those downstream devices are to be labelled "GFCI Protected” and “No Equipment Ground." Any GFCI device installed with no ground will simply be marked with “No Equipment Ground." Some continuous loads like refrigerators are not recommend to be protected by GFCI since there can be nuisance tripping.

Increasing the fuse size is the previous owner overloading the circuit and finding a bad solution. Most common way that happens is an electric heater. The most likely causes of electrical fires are arcing at device terminations. If you inspect for any existing burn marks or melting plastic it should be replaced.

Is there some similar limit to AFCI breakers? In our previous house, we had it completely rewired and they had installed AFCI breakers as part of the updated code. Those original AFCI breakers were very grouchy. I think the breakers themselves were just bad because I had better luck with replacements later, but I wonder if there were some constraints that weren't followed like that GFCI limit and it encouraged nuisance tripping.

...I mean, we could also just assume the completely rewired circuits all had problems in them or something too...

Adding devices introduces more opportunities for arcing and triggering the afci but no, there is no nec limit to those breakers other than the rated amperage. 15a - 8, 20a - 10.

Also, if you’re upgrading your panel you may as well go to 200a service for any future upgrades.

I would say that you should still, in 2024, be prepared for AFCIs to be pretty grouchy. This is just based on my personal experience of switching my house entirely to (edit: COMBINATION GFCI)/AFCIs - 21 SquareD QO (the most recent kind I think PAF? with the green/purple buttons) and another 12 Homeline. The Homelines have been fine, but of the QOs we had two that essentially just had issues and kept nuisance tripping, and we know it was the breakers because we replaced a bunch of other stuff on the circuits before replacing the breakers (with the same type) and the trips went away. The only thing that trips now is our 40 amp oven GFCI when the oven is set above 400 degrees :shepicide: (may also be when using convection, i.e. fan motor, we haven't tested that yet).

Obviously I'm not saying it's still like 2014 when electricians got their hatred of AFCIs because half of them would nuisance trip for no actual reason, and there is also a benefit to having the breaker trip for an actual issue. We had a smart dimmer switch that was broken and letting current through to ground, and the combination GFCI/AFCI tripped, properly, when the old 1970s breaker hadn't done a drat thing. Replaced the switch and all was well. So you should absolutely go to AFCIs, just be aware they're still more prone to having problems than standard breakers.

They do work fine, they just expose bad wiring both in your house and in your appliances. See the thread title.

Nuisance trips these days, if they can't be traced to a motor that needs new brushes or an ancient X10 system, effectively don't exist.

That's not what AFCIs detect at all, they're detecting RF noise on the line from arcs that happen as faulty/loose wiring heats up.

FWIW it's worth while I didn't need to I opted to do AFCI on all my 20amp/120v circuits when I replaced my 40-slot panel last year and have had not 1 single trip in my 1980 built house. This was actually a surprise to me, I had expected at least a few issues, but nothing, nada, they're even tandem AFCI breakers. It definitely seems like they've improved since those early days.

I also went full AFCI/GFCI with my panel replacement/house rewire about 3 years ago, and haven't had a single nuisance trip, but part of the rewire was also rewiring (or at least inspecting everything where it was traceable in the basement) every run to remove all the bad wiring (original 1920s knob & tube! Yay!). The only thing I've actually had problems with is this ancient squirrel cage blower in the garage, it immediately trips both my AFCI and GFCI circuits in the garage, but if I want ventilation out there I'm probably better off just getting something new in a better physical location anyways.

Er, yes, but the GFCI part of the combo AFCI/GFCI sure does detect current going to ground. Point is I previously had breakers that were not detecting anything other than overcurrent (and given they were Federal Pacific, they probably weren't detecting that either :v: ), and moving to modern breakers helped expose bad wiring/devices as you mentioned.

Of course maybe it would have been good if I'd actually said combo AFCI/GFCI but I just ASSumed everyone knew what I meant because I would be surprised if people bought non combo ones, assuming they make AFCI-only. That said, previous post edited, thanks for making me clarify as terminology precision is pretty critical in electric wiring endeavors.

A panel swap would be the safest option. You can buy a circuit breaker tracer and map the layout of your home to identify how many receptacles and/or lights are on each breaker. Our NEC recommends no more than 8 receptacles per breaker on 15amp breaker and 10 receptacles on 20 amp breaker. Your breaker size will be limited to the existing wire guage. 14g will be for a 15A breaker and 12g will be for 20A breaker.
I suspect they're all 20A but noted.

AFCI breakers can be supplied to the bedroom receptacles.
Oh? Even without ground?

quote:

My local teaches us to have no more than 5 devices on a GFCI load side if you want to save money on new devices. Those downstream devices are to be labelled "GFCI Protected” and “No Equipment Ground." Any GFCI device installed with no ground will simply be marked with “No Equipment Ground." Some continuous loads like refrigerators are not recommend to be protected by GFCI since there can be nuisance tripping.
Given what was all just discussed in the original AFCI chat, if I'm buying breakers in Year Of Our Lord 2024, would AFCI breakers now also double as GFCI protection? This is something I had never heard about. I had heard about the stickers though. Definitely noted.

Increasing the fuse size is the previous owner overloading the circuit and finding a bad solution. Most common way that happens is an electric heater. The most likely causes of electrical fires are arcing at device terminations. If you inspect for any existing burn marks or melting plastic it should be replaced.
I'd probably end up replacing all the outlets and switches anyways. What I had heard for 30A fuses is that it implies degradation of the circuits in general and the wiring involved should be set up for replacement. That was from one person though and it hasn't be substantiated by anybody else.

Also, yeah 200A service would be the way to go with a panel swap.

No, AFCI/CAFCI breakers do not include any GFCI protection whatsoever. AFCIs only trip on parallel arcs (intermittent shorts to netural/ground with arcing,) CAFCIs trip on parallel and series arcs (loose connections inline in a circuit.) Any modern "AFCI" breaker on the market is going to be a CAFCI.

You must use CAFCI+GFCI breakers (sometimes also called DFCI or "Dual Function") if you want protection for both arc faults and ground faults in your panel. This includes on any circuits where you have no equipment ground and you're using the GFCI method of bringing them up to code.

FYI, what you're talking about are CAFCI breakers. AFCI breakers do arc fault. GFCI breakers do ground fault. CAFCI breaker do both.

You're describing dual function/DFCI, CAFCI has never meant ground fault protection.

Yes. I was under the impression the C was for combination.

It is. Decades ago there were two types of AFCI breakers before they were combined into one. Then on top of that, there are dual function breakers, which add the two types of AFCI to GFCI.

Confused yet?

In an investigation, details matter.

It’s true, insulation will melt or become more brittle if there’s more current flowing than the wire is rated for. That decision can be left to the electrician doing the panel upgrade since we don’t know how long the wires were being overloaded. Obviously he isn’t going to be landing these old cables if they’re falling apart as he’s working with them and would have to recommend a rewire.

Also, id recommend commercial grade receptacles for any outlet that’s being plugged into a lot such as spots for vacuums or kitchen appliances. They’ll cost a little more but the springs will last longer.

Seconding commercial grade outlets for countertops.

AFCI terminology is very confusing as is combo breaker stuff. I had written up a post about it but everyone else beat me to it.

Strongly agree. I use commercial or industrial grade anywhere it'll be used frequently.
