Can only be done on the supplier side and not on the consumer side.
Remember,depending what tipe supply (TNC/TNC-S) your neutral & earth point is connected on the star point of the transformer.

So either the neutral is split into a neutral and earth at meter box feeding consumer board or it is split from the star point of the transformer.

When such a bridging of your neutral to earth has been done it has to be clearly indicated (labeled)
It can be easly tested with a loop tester which in turn will show a high resistance (above 1.92ohm)

If this does not rectify the high resistance then an annexture K form should be filled in and handed to supplier to notify them of potential danger

This information supplied was aimed at the post from Ettiene Swanepoel about the 220v on neutral. Also another reason why a neutral will have 220v on is due to a loose live connection.

Voltage on between incomming neutral and earth is allowed up to 25v touch voltage.

NB : All this information on rectifications are only allowed to be done by an regristered electrician or a person being supervised by an regristered electrician.
