Bonding.......again

Former Community Member
Former Community Member
Hi,


I have recently carried out an EICR on a property which probably had been victim to the Bathroom fitter. It previously has an electric shower which had been removed along with new fixtures and fittings including light and fan. They have left in a supplementary bond from the pull cord to one of the incoming pipes from the heating to the towel radiator.

Now then - My proposal, as there is no supplementary bonding (other than the pullcord to radiator), is to move the lighting circuit for the bathroom (upstairs) onto the RCD side of the CU as the Ze for the circuit complies and the Main Protective Equi Bonding is in place. I have measured low ohms between all pipework and it is 0.02 or lower. This is a more suitable solution than running a 4mm to every point.


My question is what do I do with the bond from the switch to the heating pipe? Do I leave it in or disconnect it. 


Many thanks for your time.


Chris

    Are there any exposed-conductive-parts in the room?

    Class II light fitting (LED), the fan is plastic.

    Kris H:

    Class II light fitting (LED), the fan is plastic.


    So, if the two items mentioned are not exposed-conductive-parts they need no bonding. They will no doubt have a C.P.C. run to them whether it is needed or not, as required by the Regs., but that is a different matter.

    Thank you. 


    What about the existing bond to the radiator? Do I leave it in?.....

    Either you have supplementary bonding or you don't.


    From the sound of it, you have bonding i.a.w. 411.3.1.2 and will satisfy the three conditions in 701.415.2 (iv) to (vi). Therefore you may remove what is left, but you are not obliged to do so.

    If you have carried out the EICR then you should have this knowledge !

    You could say that to anyone asking a question on here - if you're qualified and have read the regs, etc, you should know the answer,  bla, bla, bla, in which case what's the point of the forum if everyone already knows the answers.

    I believe that the concern is that the answers to the original questions are clearly stated in the regs. that Chris posted above. One about main equipotential bonding, and the second specifically about bonding in bathrooms or shower rooms. We should all have this basic understanding if we carry out periodic inspections and issue E.I.C.Rs. But I suppose on site we may wish to get an instant answer if we have left our regs. book at home, which is naughty.


    This kind of lack of knowledge of basic stuff casts a doubt on our ability to function properly if we don't know the answers. I admit that we can not know everything and sometimes we may forget stuff. 


    When I carry out inspection and testing, I write down rough notes on a pad. I then have the opportunity to look up Regs. about things if I am not certain, before I issue a full formal E.I.C.R.


    Reaching a high level of acquired knowledge and maintaining our awareness of updates and current requirements is essential to us working safely and competently.
