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....

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.

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]](https://www.electrical-contractor.net/ubb/smile.gif)

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...
