Oh my goodness!
Red wires mixed up with what looks a lot like yellow/green at the neutral terminal? Black and yellow/green wires going to fuses?
At least one black wire sneaking down to the line side... not to mention a red wire going to the box earth clamp on the right hand side...
Am I correct assuming there is a red wire going to the bottom of the left hand fuse? Would match the yellow and blue wires to the other two.
