Dear forumeers,

If yes, what are the pros and cons of the two options?

Can it be grounded both at transformer and at the power center ?

Thanks in advance.

Dear forumeers,

In a TN-C earthing system can the PEN conductor be grounded at the power center side instead of at the transformer side?

If yes, what are the pros and cons of the two options?

Can it be grounded both at transformer and at the power center ?

Thanks in advance.

 Hello,

have you already seen this:

Hello Stefano;

Thank you for these documents, they are very informative.

But for some reason the hypertext link attached to the second document is actually the same as the first.

This is the correct link to the second document; it will take you to the Electrical Installation Wiki:

Thank you,
