Discuss Rcd protection for domestic inatalls. in the UK Electrical Forum area at ElectriciansForums.net
That's my understanding of the regs now that's why in a split RCD consumer unit Hager are fitting 100A RCD's by default.Hi guys. Am I right in interpreting the regs with regards to rcds that they need to be rated equal to or higher than the main supply fuse? So not to overload them? Or am I reading it wrong?
Thanks on advance.
It's up to the installer how the install complies. A total potential load after the RCD less than the rating of the RCD will comply. If the potential load exceeds the rating of the RCD, an OCPD before the CU less than the rating of the RCD will comply.The trouble is only hager have done this and none of the other manufacturers seem to have followed suit. So cant see how they comply?
