Slightly high ZS reading

[andyww]

Hi

Have installed a new ring circuit - for a kitchen - lots of points (19 in total) - TNS earthing, max ZS should be 1.16 - I'm getting 1.41 - have checked tightness of all terminations and all are good

anyone got any ideas?

Cheers

Personelly would have installed more then 1 ring, what the total Kw that expected to connected to the ring, would have installed possible two or three ring or radial for washing machine, dryer etc is applicable.

Andyww when you did the test was your meter on the Zs 15 mA setting (limited current type) that the reason for the high reading and the difference between Ze + (R1+R2) values measured.
