Of course, because it would be. Depending upon the extent to which you'd undone the nuts and many other factors, it could easily result in disaster very quickly. That I call 'immediately dangerous'.
On t'other hand, if I had a house full of plastic gas pipework, I reckon the chances are incredibly high that nothing would go wrong in the next 20 or whatever years. That I do not call 'immediately dangerous'.

But what or who are you protecting.
Why don't you need to bond baths, towel rails etc if they are piped in plastic.
Who do you know that got a belt of a volts free room stat.
I got an interesting tingle off the boiler pipes when I turned it on after the sparky had rewired, and just before the trip for the lights tripped.
A neutral was was trapped in a light switch.
Big job just outside Bath, a phase went down neutral on the pole, every fitting in the building was live

That's Irony.
It was an Alpha which is polarity sensitive so didn't work, the annoying thing is I warned the sparky that it could take the pcb out if he gets it wrong.
So I phones him up and say get your ass down here now ( this is at my club by the way) rewired just before Christmas. To be fair he was there inside 15mins on a Saturday night. He also came in on the Sunday to find the fault as we didn't need the lights and the boiler worked with them off on the board.
I would have thought the lights would have tripped quicker than perhaps 20-30 secs

What was your second point of contact or was is capactive coupling ?
Totally out of control of the people in the building and turning the power of at the main switch does not remove the danger. The damger remains until the DNO isolate that section and ground rod their neutral local to consumers. Rare event but not insignificant,
It doesn't matter if the device actually requires an earth, you still have to provide one to every single point. How are you going to confirm polarity at the device without one? What if the device is later replaced with a device which does require an earth later on?
I don't quite understand how you think a volt free stat works, but I can assure you there will still be a voltage present.
You are protecting anyone who uses or work on the installation. You are also making sure that your work is compliant with all applicable regulations.
Because that is BONDING. We are talking about EARTHING. They are two different things installed for completely different reasons.
It wouldn't be that difficult if something was wrong with it. Just because it is a volt free stat, it does not mean that there is no voltage present.
You've got something confused there. It is not possible for a trapped neutral to cause a boiler or it's pipework to come live.
The pipes had a tingle which was quite strong when the boiler was turned on, and not, as soon as the lights tripped.
The fault is what the spark told me.
All I know is the boiler wouldn't work, and that would be a polarity issue.
I'll have to stick the meter across the volts free terminals when I get 5mins.
Shouldn't you be at work paying formy pension.

Not across the terminals as there will be no potential difference across a closed switch. You need to test each terminal to earth (assuming you have one of course).
I fancied a morning off today so here I am

yes my boiler has an earth, the controls don't though.
The scale preventer doesn't.
All my computer have one and a surge protector.
Thats the trouble being retired, you don't get that choice every day is the same as the last one, other than Thurs, Sat, Mon snooker days, today is accounts day, next Wednesday is committee meeting day.

..and also (particularly if an RCD is present) there is the person who accidentally cuts, otherwise damages, or puts a nail through, the cable.

Bernard, I'm a bit confused about your having thanked doitall for his post at 11:25pm last night. Were you really meaning to support his view that it is OK to have fixed wiring cables without CPCs - since that is the impression given (at least to me) by your thanking him?
Kind Regards, John
