New cabinets are being installed in the kitchen. Old plaster wall coverings are being removed and new insulation and drywall will replace the old plaster. While the walls are open new wiring will be staged to replace the original 2 wire without ground wiring so it can eventually be connected to a future subpanel converting to two wire with ground circuits. Wiring will be installed in the kitchen walls with enough left at each switch and outlet box so when the new subpanel is eventually installed the new wire will replace the existing wire to each switch and outlet. Enough wire will also be left near where the subpanel will be installed. The location where each wire in the current boxes gets its voltage supply will be documented so when the new wiring is connected the old wires supply can be disconnected so the old wire that remains in the walls will not be hot.
