Supp Bonding

[graham123]

if you have plastic pipes feeding a mixer shower unit, does the micer shower unit need supp bonding?

Test it and find out.

Dont get any continuity between it and any earth or main earth at db

Good!!

Are you sure? Your not getting anything through the plastic?

So because i get a reading above 1667 ohms, the mixer tap does require a supplemetarty bond to the electrical circuits in the room

Have you watched the video posted?

 

[graham123]

Yes if above 1667 ohms bonding is required

 

[Simlec]

Yes if above 1667 ohms bonding is required

And then the second part of the video!! Using your IR tester?

Good lad!

So now what are you going to do?

 

[graham123]

Have sorted it now, so, insulation resistance test between the cpc at light fitting and the mixer tap was >999 so its just a metal part and does not require a supplementary bond. Now in an EICR their is no 30ma RCD protection in the bathroom. So am i right in saying C3 as their is no extraneous conductive parts?

Confused? So your doing a EICR but don't know how to test for supplementary bonding? I would question your competency level! Sorry

 

[graham123]

Yes doing an eicr
