Sorry for this dumb question. How are you meant to get a 4mm supp bonding cable into the terminals of, for example, a light fitting/switched-fused boiler connection when their terminals can't physically accommodate it? Does the answer lie in something to do with getting the supp bonding down to 2.5mm by 'mechanically protecting' it (chased into the bathroom wall/conduit) and then it might fit into the relevant accessories? I do understand the theory of creating a Faraday Cage effect, keeping the touch voltage below 50V between extraneous/exposed. It's the practical side of it!
Thanks in advance.
