"A real danger" or not, there is obviously a requirement to bond them, without any exceptions.
I'm not really up on such things, so could you perhaps give me an idea of how much current it would take to melt a gas supply pipe?

It could be an interesting and difficult conversation.
If a gas supply pipe is such that there is "an insulating section at their point of entry, I think it's theoretically impossible to apply Main Protective Bonding (aka 'Protective Equipotential Bonding") to it - since, by definition, such bonding is only applied to extraneous-c-ps. Hence, if there is to be a discussion, it would presumably have to be about Supplementary Bonding.
There is not (and, as far as I am aware, never has been) a requirement to Main Bond something which is not an extraneous-c-p, so I'm not sure that what EFLI quotes actually represents any change, does it?
Having said that, I don't really understand how there can be 2an insulating section at the point of entry" of a gas pipe, since I was under the impression that, at least in domestic premises, it was not permitted to have plastic gas pipe within the premises. I suppose the 'insultaing section' could be ceramic, or something like that, but I've never heard of such an animal!

If I understand correctly, that is why they fit the insulating section - to prevent that.
Very few seem to have realised until now that that also removes the need to bond it.
There is no wording needed; just the removal of the incorrect parts of 544.1.2
Well they might if what they "think" is actually a legal requirement.
Obviously we all know that you DGAS about laws, and reality, but not everybody is such a ************* as you.

It certainly isn't a legal requirement for an Electrician. If these gas plumbers are so adamant that it be done then they should do it. None of this alters the fact that I am superior to you in every way.
That's a good point. I hadn't tought of that.
22mm copper pipe is approximately 60mm², so in the upper 100s of amps at least, perhaps even 1000A or more.
I was rather expecting larger numbers than that, particularly given that I would have thought that a gas supply pipe would be probably be steel, not copper.

It is a legal requirement for an electrician to comply with all manner of non-electrical laws, you tit.

I tought I taw a puddy tat.
The person installing the gas pipes needs to do this if there is a requirement within the standards they are working to you imbecile.
Are gas fitters, strictly speaking, actually 'allowed' to meddle with electrical installations?

60mm² with the holeExcept pipes have a big hole in them
380mm² if it was a solid 22mm diameter.

Seems like I miscalculated, assume the pipe is 1mm thick ?
