Hi,
Just a quick question i was thinking about today. Say if your measured ze was over the maximum value. Say for arguments sake a tncs was 0.5ohms.
Would
1) It be fine leaving it as this value aslong as all circuits fall within maximum Zs
or
2) Install an earth rod and make the installation TT, as with the ze being over the maximum value it can not be classed as a stable earth???
Aint got the regs to hand to check if theres anything in on this, and just wondered what peoples view on this would be
