10mm bonding to copper and plastic install.

[Robo]

Im going to be doing a consumer unit change. There is already 10mm boding to gas and water pipes. However the customer has has some renovation work done to the plumbing.

So it starts off copper and then goes to plastic and then goes back to copper. Am i right in thinking i need to take a seperate 10mm bond to each copper pipe?? or??

i know because i bond at point of entry to the property

haha!!....yeah alright!!!!

funny because??

Not so funny really, just sad!!!

i dont understand your inference, are you suggesting bad practice ? becuase my views are different to yours

 

[Engineer54]

I think it's more a case of your blind faith, after all ....why bother to test right??

i always test bonding conductors, so i would not call it blind faith myself, i just dont see the need to bond every piece of pipe that has had its continuity altered by plastic fittings. copper pipes are often isolated sections effectively insulated by the use of plastic connections. there is no need to bond these sections.
please dont infer that i dont test or that i am some fly by night , you would'nt like me calling you out on issues i disagree with so dont do it to me. i have managed to offer my view without attempting to run you down, unlike you sir, even though i could because you are in fact wrong.

It is abundantly clear from your posts E54 that you do not understand the reasons for main bonding.

Here we go again, and guess who it is AGAIN. Has he got his own rules cos he don't work to everyone elses

Not just me thinking it then?

Don't forget to bond that loose change left on the bedside cabinets too guys :lol

 

[sparks1234]

No, not just you short circuit, he makes a habit of it, quite unnecessarily

Thanks for every1s help

Unfortunately forums attract these episodes but at least each and everyone of us has access to the "Report Post" button which does in turn invite a Moderator to assess the situation

It's unfortunate that work is scarce in some areas. If this was not the case then I'm sure there would be less "attacks"

I hope that the OP has sifted the good from the not so good and obtained the answer he required

This is a great forum with a great deal of knowledge :applause

Another reason why bonding to all bits of copper could be more dangerous, is that if the copper pipe was isolated from earth previously then that wouldn't provide an earth path for an electric shock situation, if you now earth the pipe its then provides an earth path and potential for shock - you then have to rely on your RCDs to protect you!

Did someone say they didn't trust RCDs?

I think in E54 defence he may be thinking as I would yes there may be large sections of plastic pipes in the water installation, but if the gas pipe that connects to the boiler is most likely copper, there may be copper water pipe also connected to the boiler and therfore you may get continuity back through the water installation by the boiler.

Personally I would do an IR test on any copper pipe with in the bathroom to check if it was an extraneous conductive part, as the guys have said if it exceeds 23k ohms then I would not fit supplementry bonding to it. Again if all 3 conditions are met in reg 701.415.2 are met supplementry bonding can also be omitted, even if the metal work is an ECP
