Placing a plug into a wall receptacle while holding the plug with your hand on it is generally considered unsafe. There is a risk of electric shock, especially if the plug is not fully inserted, if there is any contact with the metal prongs, if the wiring is faulty, or if conditions such as wet hands or standing on a conductive surface increase the risk. Modern plugs and sockets have safety features to reduce risks, but it is still safer to handle plugs carefully to avoid any electrical hazards.
