service pipes/Bonding

[craig1]

Hello,

Is it ok to connect the bonding conductor of the incoming gas

supply directly into the cu block where all of the other circuits are

terminated.

As the main earthing terminal fixed to the service head has room for the

main earth only. Also the incoming water supply is at the rear of the

house and I was wondering if you can bond the pipe into the nearest

circuit earth terminal rather than running a cable back to the cu.


Thanks.

Thanks.

you can take it back to the CU earth terminal. and as for the water, NO. it MUST be taken to the MET. taking from a local circuit is not good enough

You could change your earth block though. They're only a couple of quid (from an electrical factor, not a DIY shed). Turn your power off before disconnecting anything earthlike.

he said on the service head. doubt he could change that

Earth from the service head will probably a one termination block so add a MET and connect to it with 16mm green/yellow. Take all aditional cpc's bonding conductors off that.

Thanks for the info,

As the earthing block is only one terminal do you mean to come

off this block with a 16mm earth conductor, and terminate it to a seperate

earth terminal block with room for additional bonding ie, gas/water.


craig.

Yup

One of these.

Note, the wires you put in are each meant to be clamped by 2 screws. So the picture is a 4 way one, not an 8 way.

Much appreciated
