gas earth bond

[tony mc]

So hypothetically a problem arises at that house and someone is injured (I hope not) & it is discovered that the premises has no earth ! I wonder who the finger is pointed at !

Why Wudnt there be an earth

 

[tony mc]

I take it that is not a serious question !

 

[SirusDvirus]

lol..volt pen??..just thought I'd chuckle

 

[m1ck_b87]

Could be induced voltage doesn't mean there's no earth

 

[markythesparky]

Why Wudnt there be an earth

because earth has 0v, and anything connected to it would also be a 0v. Therefore to answer your other later point, even an induced voltage, once connected to earth would be 0v! if you disconnected it and tested to a known earth you would then see a potential difference. if you connect it back up again it would be 0v.

 

[m1ck_b87]

I tested between gas bond and an exposed conductive part and it was 0v

 

[markythesparky]

That's probably because the exposed conductive part isn't connected to earth either. Therefore neither are at 0v

Edf came out and used a voltage pen on earth connection and said there was voltage, I've come and tested across gas bond and exposed conductive part no voltage

what a cowboy. these guys are meant to know what they are doing!!!

 

[m1ck_b87]

Ok but why would there be voltage down the main earth bond if There's no earth, don't forget u can get earth leakage aswell

 

[markythesparky]

I presume you mean from the EDF's glow pen? If so this is probably being induced from other circuits and because its not connected to earth (0v) it cant discharge.

No such thing as main earth bond

yeah uve got a fair point

Are you being serious?? If so I can only weep for the electrical industry and what it's become...

Do the EDF technicians have a 'yes/no' tick box for the volt-pen lighting on their inspection sheet?

Why was EDF there in the first place?
Why was he testing the earth bonding (albeit with the wrong instrument)?
Is the installation earthed?
What type of eathing system is it?
What tests have you carried out?
What are you trying to do?
Is this connected to your question in another thread?

Most of these answers are in this thread.

Well it would be nice if the OP would answer them, because I haven't seen satisfactory answers to any questions so far? Especially my last two.! It has all the makings of another heated discussion between peeps trying to help, and the OP disappearing without trace!

Agree.............but depends how old you are :8:

but come on Allan...the roles each play havn`t changed with time ...have they....
