Do an EICR and possible upgrade question! Domestic premises, TNCS, ZE 0.34 (yes quite close to max!) main fuse 60a and at some point the CU has been moved from garage to indoors, approx 8 meters away. No fused isolator 25mm tails and 10mm main earth.
So I put the main earth as a C3 and the absence of a fused isolator as a 2. I have put in a fused isolator and am not sure whether I have to upgrade main earth or not?
Second question, there is a switched fused spur in zone 2 used as a fan isolator. I could move it 600mm so it is outside the zone and blank off the original. Or could I just block off the feed and supply and rely on the circuit breaker fir isolation?
Thanks
