[QUOTE="Doc Hudson, post: 445618, member: 1607"] The same way you will confirm that any alterations you do are connected correctly. e.g. you will need a low resistance ohm meter to verify the continuity up your CPC is appropriate for the length of cable fitted. The same meter can be used to measure the L->L, N->N, E->E loops at the socket you intend to spur off. The L&N values should be within a gnats whisker of each other and both expected values based on the probably length of the ring. The E->E (CPC) will be proportional to the L&N dependant upon the size of conductor used in your wiring. (1.5mm or 1.0mm):2.5mm. If the whole continuity of the ring is not verified to the values you would expect I would think you need a bit more investigations before extending anything. Doc H. [/QUOTE]
