Main bonding showing high resistance

[Amp David]

If doing a PIR, what code would you give if the main bonding is showing a resistance of 3.5 ohms.

Code 2/3.

Bonding/earthing resistance should be <= 0.05 ohms, I believe (continuity of earthing/bonding conductors).

How, or what, are you testing?

Would it not be Code 1?

 

[Phil Mumford]

No bonding to a gas or water main is code 2.....I used to give them code 1, but new guidance is code 2

No main earth is code 1, still !

Not actually testing, its just revision for college. Just been given some 'what if' questions to answer.

Thanks for the replies.

Try the PIR guide from the NICEIC website. It gives reccommended codes

Yes agree code 2 unsatisfactory.
