So, I'm still finding interesting electrical installation solutions made by the previous owners of the house. This time we are in the loft, previously inaccessible except via a small opening in the corner of the bathroom which I once looked through. The new roof allows us to get up there and snoop around with relative ease and I thought I would remove all the old electrics before the ceiling gets demolished.
Here we find another example of "Please tell me what is right about this ?"
The cable leading to the socket outlet (tomada) comes up from the socket on the floor below which in turn is fed by a 1.5mm² twin core cable, no earth obviously!
This circuit is effectively connect directly to the meter via a number of junction boxes - ultimately relying on the 30amp main switch for safety. The junction box 'plugged in' to this socket actually feeds all of the lighting and sockets throughout the old building.

Happily, I have now disconnected all of this shambles from the electric supply and can't wait to rip it all out. More scrap copper for later.
