Hi illuminati,
First post so be gentle.
Just doing a re-wire on an extension.
Customer had a new DB fitted 12 months ago but has no certificates.
1st thing I checked was supply and type of earthing.
TNS though found that the head earth is connected to lead sheath of supply cable, connected with a standard bonding clamp which was loose.
I obviously re-tightened it, though with this being a compression connection on lead will work loose again over time.
I contacted United Utilities to come and check this out. Over the phone they explained that they use a sprung connection now, and would check it out.
They came in my absence and tested the connection and told the owner it was within limits, which it would now after I re-tightened it.
Has anyone else seen this type of supply earth connection and should I leave it that way?
Thanks
