This style of junction box had a terminal block with four screw terminals, but maybe they were paired in two, usually they were hot and neutral.ˇ

Andy, why do German electricians not use Choc-blocks inside junction boxes?

Seems like they would be a more practical and easier solution than the U-boats? And you don't have wires poking out the opposite end...

The U-Boats pretty much look like a choc-block with one recessed screw terminal....

No idea. In de.sci.ing.elektrotechnik everyone goes berserk if you start talking about those. Seems they don't really like that stuff...
The wires poking out the opposite end are one of the most awful things about the U-boats.
They're pretty much a choc block cut in half.

thats what they are...
i dont know why they're used, but really only few diy'ers use choc blocks for j-boxes here.

OK, so it's not a "code requirement" to make splices in J-boxes using U-Boats only?

Funny that in this case, the DIYers actually are making what seems to be a safer connection because they use choc-blocks.

Would you as a licenced electrician do the same if given the option? [Linked Image]

All the licensed guys from germany I've talked to in de.sci.ing.elektrotechnik would not under any circumstance use neither choc blocks nor U-boats, only Wagos. They say all srew connections will loosen over time, whereas spring loaded connections like Wagos won't. Perosnally I use choc blocks and if the screws are tightened properly I've never had any problems with them. U-boats just feel flimsy to work with and Wagos are a bit suspect to me. Too high-tech.

i in fact wouldnt use choc blocks, because any other sparkie would consider it as bungle. strange but true. totally unusual...
I like and use the wagos, and i trust them. I have see-through ones, so you can verify every single connection.


About the wire at 9 o'clock:
that was a porcelain terminal block with 4 terminals ("klemmstein").
i dont like the system very much, its just a conic shaped screw in a "u" shaped piece of metal. pretty much skill needed here to make a good connection.

i dont know why they didnt just remove the old block before adding their crap...
