Earthing after repipe

[Bahco]

I have a bungalow with the kitchen next to the bathroom.

I have just renewed all my piping as part of replacing the bathroom suite etc. I have a 10 mm earth wire coming into my kitchen from the meter and wish to earth everything especially the metal bath.

Should I attach this 10 mm to the gas meter and then from the meter go to all the other pipes?

Thanks

Are the circuits in your bathroom RCD protected?

If so no need to earth the bath etc.

The Cable you are talking about is the Main Equipotential bonding.

There should be 1 or 2 of these coming from the MET block near your meter.

Either way they need connecting (on YOUR side) as close to the stop cock and the gas using BS951 clamps.

They should be connected within 600mm (if I recall this correctly) of their entry before the first joint

There should be 1 or 2 of these coming from the MET block near your meter.

Meaning, one for your gas, and one for your water.....the list is not exhaustive though! Oil, LPG etc.

you never earth a bath!

if you dont have an RCD on all circuits, as per the above question, then you may need to bond some pipes and circuits.

Hi fellas.

Yes I have a RCD consumer box but only have one 10 mm earth cable coming from meter. If I connect this to the mains in and link to gas meter, will that be ok?

You can use one 10mm main protective bonding conductor to bond both the water and the gas providing it remains one unbroken length, i.e. you need to strip the sheath back on the cable and feed it into the tenby without cutting the copper strands, then continue the cable onto the next.
What sort of material is the waste pipe in the bathroom?

Hi SP

It is plastic waste pipe.

 

[Spark123]

Thats fine, if it was metal then that may have needed a main protective bond too.

Yes I have a RCD consumer box

can you distinguish which circuits the RCD serves, it is probable that it does the sockets but not the lights, can you tell us which ones it does (particularly the circuits in the bathroom, which is generally just the lights with the fan and shaver socket on the light circuit)

As seen in older properties, where the gas or water goes underground again in metal pipe, a main bond should also be attached to the re-emerging pipe.
