It looks to me to be a three phase supply. Red (not shown)yellow, blue 6mm?
Four twin and earths looks from here to be both 2.5 and 1.5mm being used to take away a three phase supply Black on the blue phase, Red on the red phase, and yellow green on the yellow phase. Cant see why they have reds and yellow greens on the earth terminal.
Totaly wrong but can see what he has done. Recon this was a handyman in a small industrial unit fitting small lathes or three phase lights.
Would love to have seen this on a thermal imaging camera bet the yellow green glowed like a christmas tree.
What is in those rewirable fuses tin foil?
