I didn't expect they were using so many Schuko plug devices in denmark, running ungrounded. That's quite disappointing and a very low safety level for denmark. I wonder what their electrical injury rate is compared to the rest of europe.
Also, the breaker panel in you video is really no masterpiece.
2 Wires in a breaker terminal is usually legal in europe, when the manufacturer of the breaker allows it.
But 5 wires in one breaker terminal, that's really just unprofessional.
They should have used a single wire going off the breaker and then install a junction box to split to all the other cables.
Maybe the buddy of the landlord installed it...
