Wiring a JM401: Cut an Electrification Slot

The First Gallery is for cutting an Electrification slot in the Middle Floor. I do this even if it already has a notch at the back edge so the wiring will not be compromised by a door into an extension either now or in the future, and because I prefer to do a full loop of wire up one side, across the attic ceiling, and down the other side in a single loop (no connections). This loop is the beginning of a robust and secure layout.
