[QUOTE="Doc Hudson, post: 247711, member: 1607"] This is clearly incorrect information, as by proving Ze and proving R1+R2 you have proved the entire earth fault loop path as described in guidance note 3 .and as Andy quite correctly points out, one of the acceptable methods for obtaining Zs is by calculation. This can be found in the initial testing section of GN3. mis-information such as this does not help our student members to gain a full understanding of BS7671. Doc H.

(Please ignore Technicians post #3 as that information is incorrect.) Is it describing the earth fault loop path, understanding what are acceptable max Zs values, what range to put your meter onto, where to put the meter probes, other? Doc H. [/QUOTE]
