Testing questions
I installed a socket outside (on a garden bar) which is run from a DB from the side building, fed from the main CU in the house on a 20amp.
The DB which feeds the garden bar has been turned into a TT system.
1. Would you do EFLi at the DB or main CU?
2. The 3core SWA is only connected to the MET in the CU, this is correct if im right in believing, incase anything was to happen to the SWA between the CU and DB?
3. The DB had 2x MCB and Main switch, so when doing the RCD test, it would be done at the CU in the house on the RCD which feeds the side building DB?
I hope my diagram helps my poor explanation.
Any help appreciated!
