Loose earth bond

[John D v2.0]

To give credit to Watson, he isn't being factually incorrect with those last statements, just misleading.
Since pme, (and before pme too, regardless of pme), it's indeed been regs to bond things that"may become live" (relative to the main earthing terminal, at the point they enter the house)
One that's done, there's not much else that may become live, therefore you're done.

No.

Since pme, (and before pme too, regardless of pme),

So, not since PME then.

No. That would be earthing and it does not apply to pipes nor sinks.

Bonding is applied to parts which are already earthed so that when they become live because of a fault (until the OPD opens and disconnects the supply) there will be no potential(voltage) between them.

All earthed parts could become live in the event of a fault and remain live if the OPD doesn't work

you're not very charitable tonight!

There could be various reasons for you writing nonsense? I don't know which one it is.

Looks like we've found another thing that he's not very good at.

In what way is it charitable to not point out that watson is writing egregious rubbish?

 

[JohnD]

regs.

I'm sure mwatson will soon be back with the paragraph number and wording from his copy of the 14th Edition, or wherever he thinks he saw it.

 

[ban-all-sheds]

I would caution against holding your breath until that happens....

So the cliques collective opinion is that in a steel frame building with steel floors, steel ceilings, metal water and waste pipes a metal sink does not have to be bonded.

That's a funny way of writing"regs"

Don't wait for back up, answer the question.

Do you think it (the sink in your example) does need bonding?

If so, to what would you bond it, and why?

What question? I was just obliging your trolling

 

[JohnD]

who (apart from mwatson) can see the words "steel frame building with steel floors, steel ceilings?"

I was replacing my washing machine at the weekend, and noticed one end of the earth bond was tucked behind the back wooden plate under my kitchen sink, not attached to anything.

Can anyone offer any advice as to what I need to do then?

Yes make sure your incoming metallic water supply and gas supplies are bonded directly back to your main earthing terminal.
Ignore any other bonding in your kitchen.
If you don't know how to check, an electrician has the proper equipment to check.
