Verifying earthing of a property before carrying out any work!

[jamesBoater]

HI...

Would i right in saying that it is important to first check that a property is earthed sufficiently and that readings are within what they should be for T-N-C-S, T-N-S, TT systems.

Upon discovering a house has no main earth route back to star point would it be correct to say that no work should be carried out at the property until the installation has a sufficient earth fault path?

any guidance from a more experienced body would be greatly appreciated.

I suppose my initial question was is this what should be done?

I thought we have no legal cover to isolate an installation, we can only inform the client that it is unsafe.

I don't know the legalities of it but I would rather get prosecuted for issuing a danger notification, isolating and not killing someone than doing nothing and getting some poor sod electrocuted.

Commonsense and a danger notice would allow you to isolate an installation as your the last one in the property, but if the person who lives there switches it back on your covered. IMO

To cover your back even more get your findings and actions on paper, and get the customer to sign it, if he then introduces power back into the building and something happens you have some documentation to say you deemed the property unsafe and did something about it, instead of just leaving it and walking away while it was unsafe.

Have been doing a 2357 since september 2012 and just wanted to verify some concerns i have witnessed while being at work.

As an apprentice i have many questions , after all i will be out on my own in the not so long future so need to be sure i don,t get things wrong.

If your doing an aprentiseship, and only started 6 months or so ago, it's not going to be any time soon that you'll be out there on your own!! I bloody well hope not anyway!!...lol!!


What i don't understand is that, too all intended purposes this is a PME installation, and you or your boss has contacted the DNO informing them that you have no Ze value at the service cut-out. This situation is normally taken as a priority situation by the DNO's, and should be attending within the hour, or certainly within a very short period of time.
