Municipal Earthing - Regulatory Guide

[AndyD]

If the original CoC was issued by one electrician and validated by another it's highly unlikely both electricians missed the fact there was no main earth. I'd assume, as Dave suggests, it was lost at some stage.

What earthing arrangement was the installation stated as having on the CoC? Do you know what earthing arrangement the supply authority actually provided before it went missing? There are some earthing arrangements that are the sole responsibility of the property owner such as 'TT earthing'.

Its not unusual for the the municiple earth to 'go missing'. Of the last 6 domestic rewires we have done - 3 had no incoming earth. Part the reason is the electricians who are sent out by the municipality have nothing more than a multimeter from cash converters and a few screw drivers. They always test between live and earth with a multimeter. When you bring out a loop tester they generally don't know what it is. If the multi meter says 230volts between live and earth they thibk thats fine.
