10mm pipe earth bonding / clamp

[scrapbook]

Just a quick question please.

The smallest earth clamps i can find make reference to a minimum pipe size of 12mm. The pipes in my bathroom are 10mm, I assume this will still fit okay?

Are there any alternatives?

Where I need to fit this clamp it is a bit of a tight spot. How short / small are the smallest one you can buy?

You can do supplementary bonding close to the location also - is there access to the heating pipework in a local cupboard?

How close is close would you say?

Regs are a bit vague and just mention close-by.

Can you not just RCD protect all circuits that come in to the bathroom?

are you talking water or heating pipes ?

as i doubt you have 10mm water pipes you must be on about the radiator pipes in which case can you not use a radiator earth clamp? rather than clamping the pipes?

Yes, it is a central heating pipe.

I have recently had a couple of towel radiators fitted so I can't use a radiator clamp anymore.

I am trying to make it look as tidy as possible, but it is not easy! What are the normal solutions to towel radiators because you don't generally see wires dangling from them when you see a good install!

Does your towel radiator have an electric element in addition to being heated by the central heating?

No I believe not....unfortunately by the sound of it

In B&Q t'other day I saw some Earth Clips which where effectively a ring of copper that fits snugly around the pipe and a screw through a protruding part at the top.

Is this effectively the same thing as teh more traditional earth clamps?

I will add a picture later if I can.

The one in B&Q looks like this, but it doesn't have the nozzle.

Drain down the pipes and sweat the 4mm² conductors on.

Sorry, but what do you mean by "sweat the 4mm conductors on"?
