So only defined isolation distances between phase and ground exist which would not be the case when an unisolated ground wire could just slip into phase distribution rail or into a phase connection.
EDIT: Also, the distribution panel even with the front off is defined as touch safe for something the diameter of a finger. An uninsulated ground wire that suffers an error would break that definition.
Yep, neutral is blue, ground is green/yellow striped. The latter everywhere, e.g. in a server cabinet you’ll mostly find the strap between body and door in yellow/green.
Phases, L1 to 3 are brown, black, grey. Or you may use numbered cables for rail interconnects if necessary. You can see me getting a bit sloppy with all brown 16mm² for L1 to 3 leaving the meter slots, but they are numbered then.
Every outlet gets ground, neutral and one phase, so usually I’d enter a room with 5x1.5 NYM and then connect the phases alternatingly to the outlets while forming a chain throughout the room, so phases get loaded equally in daily use.
Whenever I look at US domestic electric installations, it all looks so… temporary. Seems like there are no standards regarding cable colors, cable configuration, central distribution of N and PE, segregation of the panels contens, suddenly there’s a length of uninsulated copper in the middle of it all and a yellow isolation - I mean, you guys don’t die more often than we do, so I guess it works all out and is probably a lot cheaper.
I have no good counterexamples, but I snapped a few pictures when I redid the main distribution in the basement
…and that’s what the sub-panels per floor look like:
Did they screw the nail in?
What you need, sir, is a Lego/OpenCV based screw sorter.
Grandma called that Blümchenkaffee, flower coffee, because you could the the flower decor on the bottom of the cup through it.
It sounds exciting, it was fun for five minutes and then it was mostly cold and the cleanup was miserable. I’m voting for exercises on mild summer evenings only.
Nah, those are pretty chill around here. Usually we only see them when responding to traffic accidents or bigger structure fires and then they usually turn up way later than we do because they are stationed a lot further apart.
In German it’s called a Wasserwerfer or Monitor. I found no exact translation.
Eternal and glorious.
You overestimate the appeal of standing around in wet snowfall and waiting for everybody to cycle through all the stations in the training.
Yes, I am marvelling at the 0.08€ and I’m wondering in what kind of electrical price paradise you’re living. Bit envious, honestly.
0.08€/kWh only on a really sunny day, otherwise more like 0.3€.
Oh man, reading stuff like that I can’t appreciate enough that my house, the most expensive thing I have or will spend money on in my entire life isn’t made of a material that would succumb to a few months of unchecked exposure to a handful of insects.
Seriously. The possibility alone would leave me terribly nervous.
There might be some plastics in there the would take that personally.
I hope you have labeled the label maker first thing after unpacking.
Nah, location wasn’t stored, but still a good idea to remember to strip metadata when using catbox.
Soo… Helicoil into the block or what?
Wouldn’t say that, you just put the weight between “git er done” and safety/predictability somewhere else. Has downsides, has upsides.
