After updating a consumer unit, from an old rewireable fuse board, one of the socket circuits is tripping when under load. The property should have been rewired as the installation is so dated but the project manager and client didn't want to rewire it. The supply to the flat is approximately 10mm live and neutral tails and earth supplied through the conduit, an approximate length of 20m. Each circuit is wired in singles using steel conduit as the earth.
When the circuit is taken off of the RCD it no longer trips. I cannot find the fault and unsure what can be done to resolve this issue. I've never had to do it but I believe a circuit can be omitted from the RCD if a Risk assessment is produced but unsure if there is a possibility of this.
