I recently tested a kitchen ring main circuit during an EICR. I removed a socket in the kitchen for inspection and tested ring cont. The L-L and N-N was both 0.24 ohms. But when testing the ring continuity of the kitchen skts from the consumer unit the L-L is 0.24ohms and the N-N is 0.57ohms. I would check more of the sockets in the kitchen but someone has grouted them in place which is going to be messy to remove.
Is there something simple I am missing regarding the higher continuity when tested at the CU? Id expect it to be the same at each point unless interconnected but then all conductors would be similar. Any help is greatly appreciated. Thank you
