Same on Reddit but oh well im not rly there anymore

Yes this may be correct. There are two thin black wires besides the three phases and neutral coming from the main box below.

One of these black wires is connected to A2 of the contacter in the middle, of which I initially thought was just connected to neutral.

Oh it being a fuse makes sense, although the way it is wired makes even less sense, then. The middle device (the 'contacter'?) is not used by any load at the moment. But I wanted to start using it again.

Bottom view: Bottom view

Don't mind the loose wire. It's french wiring. It's not even connected at other end.

Global view:

Global view

I have two boilers that are now both connected to the same switch (and this is time dependent somehow). This switch is shown left. The black wires are from boiler 1, and the blue and beige wires are from boiler 2. The orange pair are neither input nor the load, so they must be 'commanding' the switch operation.

I want to start using the middle contacter for boiler 2 so that each boiler has its own switch.

The bottom of the fuse (so far right) is connected to A1 of contacter (so thing in middle) (via gray cable) as well as to A2 of switch (far left in global pic) (via orange cable).

I'm not sure whether to call it a switch or contacter again.

There is 230V between A1 and neutral (at the moment. This may change, depending on the time of day.)

 

If I use a SINGLE enter, it gets removed for some dumb reason (for "space efficiency", my ass).

If I use TWO enters:

Like this, they stay.

What if I want to list things directly under each other? My only choice would be to use TWO enters and waste even more space.

Why not just respect the single and double use of enters? Unnecessary formatting!!!

Why is A2 of the switch in the middle (E321) connected to L3 instead of neutral? Shouldn't it be neutral???

I think the switch is supposed to switch depending on whether there is 230V across A1 and A2. And the timer on the far right (E124) is supposed to accomplish this, the moment it receives "the signal" from my energy provider over mains electricity.

EDIT: Maybe A2 is not connected to L3. But it's NOT neutral either. There is:

0V between A2 and L3.

230V between A2 and neutral.

400V between A2 and L1.

400V between A2 and L2.

Thanks, I read what you wrote and made a few adjustments. Here is what I'm trying: Photo of setup

From left to right:

•Toilet tank connector. •G3/8" F connector to G1/2" M. •Fiber(?) Gasket. •1/2" (15×21mm) F threaded connector to 16mm multicouche compression connector. •The white pipe (=multicouche, 16mm). •Same connector as last. •Rubber gasket. •G1/2" threadded connector to 10mm compression fitting. •Cupper pipe 10mm water supply.

The cupper pipe changes width quite frequently, unfortunately. But I think here is a good spot.

Cut location

Why a fiber gasket and not rubber, if I may ask? I have rubber in the compression fitting. This feels better? Idk. I hope to replace the multicouche compression fitting with a press compression instead, for durability. This multicouche type is popular in France.

Any prior experience? If not, impressive

Do 4chan posts always take a 180 degrees turn?

The nut broke off and had a small red ring/gasket between these connectors. I'm an noob but can follow instructions. Please give suggestions. Thanks

Below there is a water valve Water valve which may be used as an alternative if the above (cupper?) pipe is inconvenient to use.

 

Currently, Google pays Firefox's bill by having them set their default search engine to Google.

This will no longer be when Chrome is in the hands of another party. DOJ is currently advocating for this forced sellout.

So will Firefox be no more after that?

 

This doesn't seem like Heavenly Delusion, so what the heck. I am up to date with the manga, but this creature does not appear.

Then I am stuck. I think the provided answer contains an error. But even if they are right, why does this last step equal f(x,y) + g(y) ????

 

General waste bin or glass recycle bin or neither?

I have some decade old, gruesome tall thin glasses infested with mold and food residue, cloaked in a grotesque and sticky film of decaying death that... are in no easy way to clean. What to do with them?

I think it might be dangerous to workers when put in the general waste.

 

I have my own ssh server (on raspberry pi 5, Ubuntu Server 23) but when I try to connect from my PC using key authentication (having password disabled), I get a blank screen. A blinking cursor.

However, once I enter the command eval "$(ssh-agent -s)" and try ssh again, I successfully login after entering my passphrase. I don't want to issue this command every time. Is that possible?

This does not occur when I have password enabled on the ssh server. Also, ideally, I want to enter my passphrase EVERYTIME I connect to my server, so ideally I don't want it to be stored in cache or something. I want the passphrase to be a lil' password so that other people can't accidentally connect to my server when they use my PC.

 

Any idea what animal this is? Or extraterrestrial?

 

I don't know shit about politics. All I know is that in the UK the Labour party won, and the Conservative party lost.

I read some protestors are protesting against racism. What is this about? Protesting against new party that just won? I thought the Labour party was left-wing, meaning they are more on the social-equality side? I'm lost.
