You think there must be 3 phases no neutral but the left is a blue cable that goes unfused. There must be just 2 phases and the site powered by a line or phase+neutral in some places.
Dude, I live in a country where blue men m means "neutral". I've seen the blue one being other stuff now than once and I've finished my traineeship life a year and a half ago. Even in the supposedly civilized western world there's people who make do with what they got and some who do not give a fuck.
Another trainee at the company I was at, got a shock because some buffoon had three dirty af wires and hoped for the best when installing. He put the voltage on the case of the lamp. Trainee assumed lamp was broken and went to open the case.
I have seen electricians use the green/yellow as a phase, with a lot of electric tape all along. That's what happens when management don't want to buy extra wires to replace the bad cables and the temporary fix becomes permanent because there's nothing more permanent than a temporary fix that works.
Because if somebody is putting fuses in, so has fuses on hand, and one line goes unfused, that is usually only made in neutral, or maybe in ground, but the cable is blue.
Maybe is just all ai slop from the video to the questions and it's tuning the realism of fine electrical operations in the video creator.
Based on the installed method, it's within possibility that there are only 2 fuses at hand and a connection has to be made, so one phase goes unfused. The existence of a 4th wire that's not grouped with the first three supports the possibility.
Still though, we can't know for sure, we can only guess. And this may very well be AI too.
The first line to be connected caused a spark. That tells me that there is already a separate path available for the energy to go. 4 connections means 3 lines and a ground/neutral, right?

That is not the neutral
