Yes but that's nothing to do with main protective bonding of extraneous parts :mtongue: although it is part of ADS
Except main protective bonding of extraneous parts is in sec 411. This could go on all night, but suffice to say those with more intelligence than me, have bonded metal internal with plastic service. I'll just follow their lead.

i would say bonding a piece of metal not extraneous could introduce a shock hazard (during fault conditions in the installation) which might never have been there because it wasn't needed such as isolated from earth metal workExcept main protective bonding of extraneous parts is in sec 411.

that's why any metalwork should be tested to determine if it's extraneous. 22kΩi would say bonding a piece of metal not extraneous could introduce a shock hazard which might never have been there because it wasn't needed such as isolated from earth metal work

Might have to up my estimate to 145 posts at this rate.

if the pipework entering the bathroom is not extraneous and all circuits meet their requirement for disconnect times and rcd protected they would be no need to supplementary bond pipes anywayAs an aside, if you don't bond the metal pipe work (after plastic), you'll probably or may have to supplementary bond incoming metal pipes into special locations, perhaps

I'm down with the kids when it comes to this mobile texting lark!You type quick, were you poised with a reply

A measurement can be made to verify the effectiveness of the pipework connected to a main protective bonding conductorForgetting ancillary earthing, boilers etc. How likely are those pipes effectively be bonded to earth? I would suggest, apart from following like sheep, that's the most cost effective way of following reg 528.3.4 that most installs I've seen, seem to follow?
