How to make grounding in a hostel if it is not?
Hello. There is no grounding in the hostel, what is the best way to do it? Pass a three-wire cable from the apartment and fix two wires in the common floor shield to the zero level. Or spend two wires and already in the apartment in the shield, divide the zero into two tires - “zero” and “ground”? Thank.
If grounding is not provided in the building, then independent "grounding" is fraught with negative consequences. In the event of zero burnout (PEN conductor), a life-threatening potential will appear on grounded electrical appliances. This situation can arise both in the case of grounding on the floor, and in the case of separation of the PEN conductor in the apartment - both options are unacceptable.
