Nice to see all the cables have earth wires and they are not being used as switching wires. As you probably know the earth wire protects the cable from Jo blogs home owner cutting through the cable and electrocuting him / herself. Unless if the circuit is protected by a RCD that trips on earth leakage current, a fuse / mcb trips on over current. A low resistance path is needed for a large enough current to flow. If someone cuts through a cable a large current would flow to earth through the earth wire. If there was no earth wire the body of the person cutting the cable would become the path to earth.
Good vids. Keep em coming.
Thanks for your comment we really appreciate your feedback.

Well explained!
Never going to hurt having something earthed, we’re bib and braces people where practically possible.
