Erroneous statement followed by a non sequitur... Mmmm useful ;-)

The OP reported that connectivity had, to his surprise, been found
between his neutral and earth wires. It is a requirement that the local neutral wires must, somehow, be electrically connected to the terrestrial Earth, and it is a requirement that the local earth wires must, somehow, be electrically connected to the terrestrial Earth. Therefore the reported connectivity is required to exist, and so should be expected; it occurs due to at least one connection, somewhere; such a connection may be man-made metallic or by way of the terrestrial Earth (or by any other reliable means, if any is possible).
