Evening, may I pick you brain guys?
I have wired a summer house about 30m away from the main board. I have used 32A at DB1 (not RCD protect) and 6mm² 3core SWA, where I have connected both black and sheath (sleeved) at both end as CPC. In the Summer house I have used shed consumer unit 1xRCD and 2 useable mcbs.
I test Ze and PFC at DB1. I then move to test the shed DB2 RCD, Ring final and light circuit.
I am wondering
1. if I use Zs at the DB2 as Ze while filling the cert or do I use Ze and PFC from DB1?
2. I have added a 32A mcb at DB1, do I test the whole DB1 or Ze and PFC from there are enough?
What are your thought guys?
Regards

Ze and PFC are done at source, Ze only occurs at source assuming you have not TT'd DB2. There is no need to test all circuits from DB1, just your new circuit.

One section of the EIC is for supply characteristics and the SOTR is ZS and IPF at DB

Usually on the top of the test results section page of the cert there is a box for zs and ipf reading at origin of your remote 2way cu, but this is only on the last test results page, its always worth measuring these values as part of your testing imo
