Some really bad electrical stuff dad. Look…..
I was particularly impressed at the technique used to bypass the RCD of stuffing the load tails into the screw access holes of the feed terminals!
Interesting connector block at 10:30 - connecting the old colour wiring (red and black) to the new colour wiring (brown and blue). There was no mention that it was connected red to blue and black to brown and so switching the live and neutral.
