Now that has to be the roughest install I've seen in a while.
I once saw a guy(a wannabe security installer), that had a long(I mean 40') of TPS(like Romex) cable tied around his upstairs balcony railing, connected to an outdoor socket-outlet, that wasn't on an RCD, but just had the wires poked into the slots of the socket.
And this fed his whole "alarm" system and security lighting installation, that was over the other side of his property.
I told him to take it down, before I "saw" it.
I later found out from his wife, that the back gate was livened at 230V, too!.
He dealt in Drugs, I have no time for these sorts of people!.
