My current multichannel amp has two power supplies and one additional smal smps for vumeter.
I would like to know what sort of connectors is considered safe to use to split main voltage: one in, three out.
In typical household multiple socket hack, I would use this sort of thing:

and cram two wires out, and one wire in, instead of one - one.
Now, I would like to make it safe in this amplifier and prevent main wires from popping accidentally out.
What sort of terminal block is considered the state of the art today for power distribution? I also imagine regulations are not the same in EU than other countries, so I am looking for EU approved connectors. The wago stuff looks nice, but they look like they are made to extend wire?
Ideally:
Thanks a lot!

Ideally:
- no visible main wire or metal parts.
- chassis connection (screw) to prevent said terminal from wiggling in the enclosure.
Thanks a lot!
I assume you wish to split the mains inside the amp?
I'd be tempted to fit an IEC socket for the mains input to the amp and solder my 3 internal supplies to the terminals.
Also consider if the VU can be powered from the amp power (perhaps with a low voltage regulator).
Then only 2 mains supplies.
Otherwise, use the chocolate block as you suggested.

Strip blocks are not liked in many areas as they are not reliable in the long term. I know some large companies that banned the use of strip blocks and one never knows what quality they are as most are unbranded. Electricians use these as a standard nowadays as these are a more reliable and safe alternative: Wago 221.
Wago made some mistakes in the past and their products used to be less reliable than the good old wire nut (still the very best for solid wires) that they vigorously tried to kill. However this product is very good. It accepts both solid and stranded wire (both of course without wire ferrules). Don't worry about wiggling, just tie them together. Mounting plates exist but one rarely sees those in the wild probably because their existence is not widely known.
Alternatives:chassis mounted fused connector blocks with screw terminals or crimped closed end wire connectors like Japanese devices often have.
