Hello all,
Just a quick question regarding I+T that I wanted to get some clarification on:
1. I recently went to a job where the incoming cables from the street came up through a metal conduit from the ground and then ran through some metal trunking before terminating in three sealed fuses (which was essentially the cutout). A 6mm earthing cable was clamped to this incoming piece of metal conduit and ran to an MET before terminating.
My questions are: a) is this a TN-S system? b) is the length of 6mm what I would class as the main earthing conductor for the installation.
Any constructive response to this would be appreciated. Thank you.
