My friend asked me to install a radial circuit in his garage for an electric garage door. The CU is about 1.5 meters away from the door and there were spare ways in the board, so ive just put a radial circuit on a 16a mcb. Ive put a FCU in and a double socket at the end. Quick test to make sure its all ok, even though i can visually see everything is fine. Linked line and earth to preform R1 R2. Getting a reading of 0.10 ohms, switch the socket off.... still getting 0.10 ohms. Am i missing something glaringly obvious here? surely when i switch the socket i should loose continuity??
