no evidence of supplementary bonding to pipe work

[egginyourface]

I went and did a visual inspection on a flat. No Rcd protection present.

10 mm earth to water and gas was connected.

No sign of supplementary bonding. So i did a long lead test and found that all pipe work in kitchen and bathroom was below 0.05 Ω.

Does this mean no supplementary bonding is required?

Ive advised the board be upgraded but dont think they can afford it

If you check reg 701.415.2 then you will probably find it is.

Cant afford a board change but can throw money away with a visual inspection? unless you did it for free

I would not worry about the kitchen as its not required under BS7671.

In addition to reg 701 and doubt exits re the effectiveness have a look at reg 415.2.2 but you will need to do some testing to establish if it is connected in the bathroom!

Hope this helps!

Would it be satisfatoctory to upgrade lighting circuit, shower circuit to rcd

Yes then supplementary bonding may be omitted as long as the 3 conditions are met as per 701.414.2.

This is where the Visual Inspections are worth nothing IMO as the only way you can establish the above is by getting you test equipment out!
