To start the routed cable (wire) – in corrugations, and then use special clamps fasten it to the walls of the wooden house or apartment.

As a result, one end of the wiring in the corrugation will be points where you need to be connected, and the second at the installation location of the electric panel.

For this it is necessary to mount additional wire (e.g., PV3 1×4) from the main distribution panel in the common hallway to the bathroom.There is also another barbaric method is to score the wall iron pin with a diameter of 10 mm to a depth of 1 meter. This can be done only in the case if your house is concrete walls.
  5. For lighting you want to apply a safe voltage.Of course in 90% of cases this item was not respected and the lighting is powered from a fixed AC source voltage of 220V.To resolve this violation, you need to redo the power supply circuit of the bathroom and install outdoor step-down transformer 220/12V.
