So... discussion about "Hot Water Heater" vs. "Regular Water Heater"... I was assuming this was a joke regarding the redundancy of the term "Hot Water Heater" since "Water Heater" is already making the water hot, so why would you need to heat water that's already hot? Similar to RAS Syndrome, I thought Randall was making fun of that, but the explanation has a different idea... which... kind of makes sense? But...

Regarding the "one surprise mystery outlet", I don't think it's necessary to assume it was wired that way by mistake. When extending the wiring in an existing house, it's not always easy to wire up an extra breaker, or use the most logically labelled one, and there may not be a compelling safety reason to do so. For instance, in my parents house, the original sockets are all wired from the floor, and when an extra one was needed for a boiler control, it was easier to run a conduit ''down'' from the floor above; so that particular socket is on the [https://en.wikipedia.org/wiki/Ring_circuit ring] marked "Upstairs Sockets" on the consumer unit. - [[User:IMSoP|IMSoP]] ([[User talk:IMSoP|talk]]) 09:18, 31 October 2023 (UTC)

I read the "state/federal law" switches as ''required'' by said laws. i.e. respective building codes require a "foo switch" always to be installed, whether or not a foo is required, reasonable or even practicable. The switches may be left unlinked to anything that is serviced, or run to the household outlet/power-switch with the label plastered over it saying "don't use for anything but the quarter-inch hoojamaflip grinder" (or whatever it is, in the same sort of manner as "Refrigerator, do ''not'' unplug/turn off!" in a communal kitchen....

:: You guys are way too serious. It's a joke, so pick the funniest interpretation possible. Don't try to make it realistic. A circuit breaker turns off the electricity so you can work on the wiring without getting shocked.

...in a separate comment, I have a fuse/switch labelled "Do not turn on!" in my house. It was turned on when I moved in, and (barring actually any reason to mess with anything/’get a man in' for any other purpose) I've ''left'' it on. Ditto, for these last six or seven years I've remained ignorant of the purpose of various wall switches (floor-height, one in living room, one at top of stairs, another in a bedroom) that are unlabelled and off (though I ''have'' switched them on... no obvious difference to lighting, alarm system, any other system I can imagine they're wired up into and left it pending some future time when I actually have to do something like strip plaster back and discover which (if any?) run of cable leads from/to them. [[Special:Contributions/141.101.99.166|141.101.99.166]] 10:11, 31 October 2023 (UTC)
:Regarding wall switches that don't have any apparent purpose. Many houses or apartments were not built with lights in the ceiling. So all your lighting came from lamps plugged into wall outlets. They would wire one of the wall outlets to a wall switch, usually near the door. This way you would leave the lamp turned on and use the wall switch to turn it off and on. It takes a little investigation to figure out which wall outlet is being controlled by the switch. [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 12:43, 1 November 2023 (UTC)
::Not applicable, in my case (above 'owner' of the floor switches) because all my sockets(/outlets) in my house have switches ''on them''. One of the mysterious floor switches is indeed very close to a wall-socket, but that wall-socket is a double already with two independent switches ({{w|File:Uk 13a double socket.jpg|example image}}). And is of a very similar vintage to the 'mystery switch', by both actual appearance and the how the wallpaper/etc looks. (The house itself is 1930s vintage, but clearly fully updated and rewired to essentially modern standards some time in the last 50 years. No reason for a 'leftover' separate socket switch to have remained/been kept instated.)
::The two main possibilities of purpose that I still imagine they controlled are: 1) The burglar alarm, and 2) The storage heater. Originally. Assuming you'd even want multiple different control-switches. But completely bypassed by a later reinstallation. The newer central heating (replacing the storage system) is entirely controlled from a kitchen wall switch, and its own fusebox breaker. And the alarm system has a hallway pad and if it was ever connected to the "Do not turn on" switch (that was actually on), it hasn't suffered at all from the experimental instances of it being turned off (when I thought I'd check).
::...it'll all have to wait until I have the next major overhaul, I think. I'll get the next electrician I need (perhaps when replacing the current boiler, or needing more sockets in the workroom) to try and work it out using their usual tricks and tools.

Amongst other things, there are problems under the "no friction" section. e.g. You might have a perpetual motion machine that would go forever, but without something else (e.g. the anullment of 3LoT) it couldn't also ''do external work''.

"A circuit breaker ...to... protect appliances." --- A pedant would say the breaker protects the wires. When the box is specced and installed, the appliances may not have arrived, and are sure subject to replacement. In both the US and GB Codes the breaker size relates to the wire diameter. If an appliance needs greater protection it should have its own fuse/breaker. Some do, though the trend is to appliances which will fail without flame, smoke, or loud noise.
:It's a chicken-and-egg. If you've got a high-current device to install (e.g. electric cooker) then you'll ...hopefully... make sure it has thick copper cables to its outlet, and also sit it behind a fuse/breaker that will take the power throughput. But you still want your breaker to 'break' if something shortcircuity goes on in the cooker. Even/especially if the supply cables are happily feeding the power to it, or its own local fusepoint, because they're not so tightly toleranced that you end up with a long 'heating element' passing through the kitchen wall as well as on your cooker's hobtop (or in its grill/oven compartment(s)).
:Overspec the wires, try to tightly spec the current limits on the switches as much as you can anticipate will not ever false-trip. (With the switch from incandescent to LED lighting, many a lighting circuit will now be much further from failure, than designed, but actual ground-faulting will still likely trigger the RCD/whatever.) The aim is to never get so far as a breaking more circuitry than an intrinsic fault has already broken. e.g. motors may burn out, if something jams them, but ideally not spark across to the casing that houses them if they don't suffer direct physical damage.

"Bathtub drain light" My bathtub drain is plastic pipe. If the lights are off in the bathroom, but on in the cellar, there's a "light in the drain". No, I don't have a dedicated breaker but that's an idea.....

"Hallway floors" My last house was 1830, so all the electrics were hacked-on. We had a floor outlet in the hall. This used to be more common above a wireable cellar, it avoided snaking the wall. [[User:PRR|PRR]] ([[User talk:PRR|talk]]) 20:14, 31 October 2023 (UTC)
:Floor outlets are pretty common in large rooms. I mean rooms larger than you'd find a house, say a large classroom. They're used for things like floor polishers or vacuum cleaners, that need to be plugged in near the middle of the space, because the walls are too far away. Also, meeting rooms often have floor jacks under the central table, so people can plug in laptops. [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 15:12, 1 November 2023 (UTC)

If only people were like books... (I have (re)read far more Asimov and Clarke than Wells and Zelazny, but none of them complain!) ...but clearly ''no'' absolute ordering is perfect. "Most recently contacted" suffers from the problem of some new contacts shuffling someone out of the current head-of-list spot and then they plummet to the 'old' end. "''Least'' recently contacted" would be better, but would 'auto-ghost' everyone the moment contact is re-established (or attempted, if it was based upon your reaching out, not their deigning to reach back again).
 Perhaps a "rolling road-block" method of (say) today starting at A, tomorrow starting at B(/wherever you left off today), and so on until it wraps around Z->A again. Or half your "social management" spent at the top-end, a quarter of it jumps half way down, an eighth of it half of the rest of the way, a sixteenth by jumping a further half of the remainder, with discretion to look up and down from the proposed landing-point to choose a neighbouring contact with more hopefulbcontactability... That latter would work even better on a "by most recent contact" sort, as well, as it churns and refreshes the current social circles to regain valuable 'lost' contacts without overly penalising the current circle of recent acquaintences in such a paradoxical manner.
 Of course... the fewer friends you have, the simpler the problem! I have never been so happy to be a sub-Dunbar individual, and so not have all the anxieties that those with exceedingly active social lives must have! Even if it means I might just have to phone my water-company up, every now and then, to bitch about how my telephone company forgot my birthday and is now refusing to return my calls... ;) [[Special:Contributions/172.70.91.69|172.70.91.69]] 09:29, 15 June 2023 (UTC)
:Wouldn't it be easier just to have randomised ordering each time you load?

:: I get the feeling that Randall alluded to an error of that kind to indicate how Cueball's over-thought 'engineering' process was actually under-/mis-thought as a 'social' one. But perhaps he didn't realise how non-obvious the comic motive was. Because, without the 'failures', it might seem that Cueball is actually being both practical and efficient (until the punchline). And I might suggest it was because he had outdated contact info (fits with the lack-of-recency idea), someone else might imagine it was because they were in another city/country (because he's so indiscriminate in who he contacts), etc. Better to speculate than to edit-war as those who are (differently) confident try to impose their idea on those who don't know what is going on.
:: Alternately, he (Randall) ''knows'' there's multiple problems he (Cueball) is falling for. In which case those in need of explanation also need to know the range of issues.
