Bonding to plastic pipes.No gas to dwellings

[circuitsolution]

Hi all
Currently working at the block of flats(5).No gas supply to the building.Water all plastic from incoming supply to throughout the building.Can we omit the protective bonding to all the flats.
Any information will be much appreciated.

You need to connect main bonding to all xtraneous conductive parts entering each installation.

As long as there is no metallic pipework in contact with the general mass of earth entering the flat then there's nothing to protective bond to.

Is there any internal metal pipework?

Is plastic an extraneous conductive part?!

good job we'renot still on the 15th.some would be bonding plastic windows.

I believe the 18th will "clear this up"

NAPIT's tech team told me that if less than 1 mtr copper incomer no need to bond

God the question of to bond or not to bond will still be asked when we are on to the 25th edition! Ha

Must be correct then

Hi - no offence to those guys, but I don't recall the "one metre" bonding rule. I'm guessing they didn't put it in writing?

only an over the phone reply

Arrgh, schoolboy error. Always contact these technical support desks, via email.

No metal pipe work at all

Bit old for schoolboy error more like old boy error

No metal pipe work at all

I was thinking about reg 528.3.4, which will not apply here then.

 

[davesparks]

It is all extraneous parts which need bonding, not just pipes.

Agreed. Its just an often overlooked matter where the service pipes are plastic, but the internal pipe work is metal. Reg 528.3.4 does not specifically refer to extraneous conductive parts, just non electrical services, although they are referred as such in 411.3.1.2.

To be honest it's a long time since I looked at the regs concerned, I might refresh my memory later when I get home from work. If I'm not too busy cooking dinner

Please do davesparks. Although I have nothing specific to back up my understanding, I believe it is to negate the probable likelihood, of pipes and cables coming together under the floor boards, and the likelihood of a pipe becoming live. Unlike a pipe likelihood to introduce a potential into an environment, this is simply to bond such, bit like exposed conductive part. That's my thoughts anyway.
