I have installed a Wylex 17th Edition DB at a property and everything has tested fine (both dead tests and live).
I've then used a MCB (RCD protected to supply) a DB in the garage. No RCD present in the garage as it's under the RCD in the main property.
However, when I perform the Prospective Fault Current Test – between Earth, Live & Neutral – the RCD in the house trips.
Any ideas ???
