Is it possible to ground in the apartment to the elevator shaft?
In a multi-story building, the TN-C-S grounding system. But the cases of PEN conductor burning off in the Input Distribution Unit (VRU) became more frequent, which creates very dangerous situations when operating apartment household appliances.
The house also has an all-metal elevator shaft, which is electrically very reliably connected to the PEN bus that goes to the supply transformer. Is it permissible to make the grounding of the apartment network (PE) autonomously by connecting the PE wire of the apartment to the metal structure of the elevator shaft ?? (If permissible, what provisions of the PUE, etc., are allowed)

I’m already wondering how from each elevator there will be a bus to the transformer. Just wondered. No, you can’t do that. As if can and should work wellbut you are looking for “what is allowed”, and you need to find out “what is prohibited”, this question needs to be asked by the management company if they are allowed to connect the ground to the mine - please, if not - you can’t prove it in any way, since this is a public place and thus you may endanger other residents in the event that PE burns away from the shaft (driving away sooner). Everything in apartments and entrances does not fit the concept of “autonomous”.
