All finished!  I did go with the old work cans, and boy am I glad I did.  I was able to do the majority of the work without even going into the attic.

In the above photo I installed the can by the door and then snaked the cable across from the other hole, in line with the ceiling joists.  This turned out to be the only possible way to go, because I would not have been able to reach that spot from the attic -- as I've mentioned before, it's very densely trussed and I simply wouldn't fit.  I barely squeezed into the spot above the old light (upper right in the photo) to make the final connects.

(That's actually a photo from last year's ethernet project but it's a visual of how difficult this space is to work in.)

Wiring was problematic.  The existing light was on a three-way switch pair, which had somehow been made up using 2-conductor cable.   (No, they didn't use the ground wire as a neutral; I checked that.)  I marked each conductor to keep track of which ones were hots, neutrals, and switch legs.  And there was another light downstream from this one.  I still can't figure out how they did it.  There has to be a borrowed neutral and/or a hidden traveler somewhere, which I suppose was code compliant in 1991.  I know that the 2011 NEC 404.2(C) requires a neutral in every box, whether you need it or not.

(Yes, the kitchen is a mess.  This weekend's project was installing the lights, not cleaning up the kitchen.)  I'm very happy with the results, but very sore from climbing around those attic trusses.

Good job and congrats on the new lighting.

(I think we have the same cabinets)

The emblem under the sink says that the cabinets are made by "Merillat"
Pretty ordinary contractor-grade cabinets.

Nicely done, we need more light in the kitchen too, but have not attic above. And I do not dare to uncover the hidden treasures this ceiling holds underneath the wood. We had a two spot LED thing, but all three we had in the house died. Will replace with a four spot LED thing. Ugly, but damn bright.

Sounds like this one:

Or the Carter system (Hamburger Schaltung in german): https://en.wikipedia.org/wiki/Multiway_switching#Carter_system

Carter system looks interesting! I'll bet it still has uses in low voltage applications. But as the article points out it's been forbidden by the national electric code for many decades in the US, and my house was built in 1991.

The wiring shown in that diagram you attached ... maybe something like that was done -- it would have been code compliant in 1991 when the house was built, but not after 2011. So maybe!

Things were complicated by the fact that in addition to the cables from the breaker panel and the two switches, there was another cable coming from additional downstream loads, and that cable must always be energized. I tried to trace it out, and I'm pretty good with this kind of stuff, but in the end I just put on labels and wired it back the way I found it. There's got to be more than I see there.

One of the cans is close enough to the counters that I *almost* don't need the light over the sink anymore. So at some point I think I'm going to remove that light and replace it with LED strips under the counters.

I have bought a wire tracker in order to do electrical archeology in this house. You can get them el cheap or insanely overprized, I bought this one here and is totally ok:

It can check RJ 45 cables, too, I often use it in the office of clients to check wether a LAN wall socket is usable or not.

Can it trace electric wires?  I'm pretty good on my low voltage plant right now, but I've got a lot of abandoned electric wires, and some of them are in places where I'd like to light them back up, if I could only figure out where they go...

Yep, it has these crocodile clamps. I used it for lan cables, telephone cables, tv antenna (satellite and terrestric) and ordinary 240V cables. As long as it is conductive, it works.

Helped me to detect that some retard had screwed our curtain rail into the antenna cable... still took me ours to find.

The metal tip you use as a sensor can detect through the insulation of cables, stone and wood, but gives the best result if you can touch a wire directly. Of course you need to be sure that the cable is off the grid when you check higher voltages. IIRC, it can work on small, low ampere voltages, but I would always rather make sure they are turned off.

I had trouble singling out a cable the closer I got to the fuse box, probably because of interference from live wires. Or the sheer amount of copper.

But for checking dead cables or finding the right ends for light switches, etc, it is a bliss and fully worth the 20 bucks.

Fleeb,

I can't remember the room where you talked about how long you have been out of your condo, I spoke with my sister's friend.  After he was flooded out it was 84 days from the time the place flooded until he moved back in.  So it took about three months.

I misread that as "checking for dead babies"

Pressure washing, especially cleaning stone or concrete is very satisfying.

Getting an auto-start generator installed.

In spite of this being a contractor that specializes in such generators - and having previously conducted 2 design walk-throughs, they still brought the wrong size gas pipe, the wrong electrical shed, the wrong pad.  We finished visit #3 today and apparently still need visit #4 (to get the right sized gas pipe).  <face::palm>

Natural gas or propane? I always found it odd that there are so many homes with natural gas fired generators installed, when the whole purpose of having a generator is to have electricity when the utility fails ... but natural gas is another utility.

And of course, the fact that natural gas service almost never fails (at least in the Northeast) is a good argument for putting all electric service underground.

Over in the foreign nation known as California, on the other hand ... they've got a ton of seismic activity over there, so they shut the gas off on a regular basis.

Natural gas.

You're right of course, and I considered that.  However, propane must be regularly filled....which I may not be able to do if I'm not home when said electric failure occurs.  Also, (ptu-ptu), our natural gas lines have been exceptionally stable here; the electricity that fires my sump pumps, not so much.

Well, this room is not a complete fit for this, but it's close enough.

Some of you may remember how I found myself displaced from my home for six months while Bubba and Hotep played at Home Restoration, ultimately returning my home to me with several details done... poorly.

As in, paint in places where paint should not be, while paint seemed to go missing in places where it should be. A garbage disposal left inert by an extreme lack of electricity powering it. A dishwasher inconvenienced by a range such that it could not open fully since the range wasn't installed all the way to the wall as it should have been... not that it would have mattered, as the dishwasher suffered from the same extreme lack of electricity as the garbage disposal. I often wondered if I had been able to power it, if the garbage disposal would contribute in some way to the cleaning of the dishes, but I never got to find out.

And so on...

I don't know if I pointed out that we did get the more expensive of these issues addressed properly after a series of calm but firm meetings. I didn't completely freak out, unlike the African mother who completely lost her mind a few days ago after locking herself out of her condominium. I just calmly pointed out my lack of trust in the quality of the vendor's workmanship, asked the board to pay me to hire my own team, ultimately using the people I didn't want to use (but having certain very firm assurances in place that we should see true improvement in a timely fashion). Ultimately, they took care of it, and it seems pretty good.

And then I got a bill from another division of these guys for two of the months my property sat in their storage.

They said it wasn't on the invoice, and I was lead to believe I did not need to pay it... after all, I caught these guys not actually working, and the job should have been finished within four months, so I kinda thought they should eat at least that little bit of money. But, no, she said I have to pay it.

They waived it after I got the two divisions in sync with each other by asking the other division if I am still expected to pay it, and pointing out some discomfort at the idea given the delays.

That's about $600 saved by keeping a cool head and calmly asking questions.

I had planned to pay it, then bill the association (suing them if necessary).
But I had hoped it wouldn't go that far.

Damn, Fleeb......

At least you got to keep your $600 without careening down a ski slope on a bicycle demanding your dollars!

I spoke too soon.

The kitchen sink has sprung a leak. That was one of the items touched by the knuckledragging baffoons masquarading as plumbers.

Likely, the plumber who caused this to happen is the same person who complained bitterly about coming to my home to do such easy work.

At least he gets to complain about coming back.
