Duplication of the ground wire from the apartment panel to the floor
In your article about DSUP says: "At the end, the wire is connected to the ground bus in the shield, on which the installation of the additional potential equalization system is completed. We recommend you to play it safe and call an electrician so that he checks the system’s performance with a tester and a visual inspection! ”
Question: To create a DCESS in an apartment, is it necessary to duplicate the ground wire from the apartment panel to the general floor?
Hello! No, you do not need to duplicate the ground wire.
Tell me, within the framework of the control system, do you need to ground the reinforcement mesh of the screed in the apartment?
That is unnecessary.
