Zones for main protective bonding

[Pondy]

Hi,
been a lurker on this forum for a long time, but this is my first post, doing some electriclal work which i will be using for my niceic assessment, need to run main protective bonding to the gas meter which is in a unit underneath the kitchen sink, the only way I can see is to chase in by the corner of the door and along the top of the skirting board into the unit, would this be ok as obviously it is not in a zone, just want to make sure as don't want to be tripped up come assessment time with Mr niceic.....

If you get desperate for lack of zones, put in a flush backbox and blanking plate. Run the cable horizontally and/or vertically from there.

Any chance of going outside wall and clipping external

i would never clip outside personally , I prefer mechanical protection, PVC conduit if its a light use area , galv conduit if it near a public pathway .

do bonding cables need to be in a zone ?
how much current do they carry ? ;-)

more exciting questions after the commercial break !
:-D

depends on conditions or was that a trick question? Lol all cables should be run in zone in my opinion, bonding as much as any other, you cut through a bond you don't know you hit anything else It tends to go bang. Then at least you know.

Cheers Steve, can't be doing with this cold weather back in the UK, what is all this white stuff???

Good to see you back mate. where have you been? The forum has been overrun by DIY idiots and numpties over the last 6 weeks

so really the only way of doing it properly is to either bury more than 50mm in the wall, or have earthed steel conduit etc. seems a bit daft having earthed steel conduit when it is a earth conductor in the first place. as there is now way of getting the 10mm to the gas meter in a zone, what can I do?? seems crazy to me

I've heard about this white phenomenon that seems to be spreading over the country but I've seen non of it, only white stuff here is caused by seagulls. Good to see you back though.

So you didn't like my suggestion (post 16)? Or is that not possible?

I have considered it,it would have to be in the bottom corner to do both the up part and the part along the top of the skirting board and it would look a bit out of place, am considering putting one in place for the niceic man then removing afterwards...

Hahahahah, welcome back to hell you double hump rider.

Camels are supposed to be water retentive, probably wrong there, British women though on the other hand......

I wouldn't worry too much about zones in this instance, as the bonding conductor is not a circuit.....be hard to RCD protect it etc.......I would do as already advised though and try to avoid any chasing, as is much easier

Nobody seems to know about zones, and that includes some electricians:joker:

True, but it does ease the conscience if you had to be naughty......not that I would, well not usually.......:devilish:

Think I would say that you maybe one of those electricians that struggle with regards to CABLE and zoning.

As the OP stated it is a 10mm conductor I would assume it is a cable and as we know regulation 522.6.101 clearly states that a
cable concealed etc etc.

So it as nothing to do with it being a circuit or not, a cable buried is a cable buried and therefore needs to be afforded the protection required in the regulations.

Also if you want to read the regs an rcd is only one way to protect a CABLE there 4 others

well that put me well and truly in my place…in the naughty corner where I belong…and to be honest Iam one of those that struggle with the concept of zoning cables to avoid them being damaged, when NOBODY else seems to know about the zones or where they are etc etc……and before you all attack with cries of 'burn the witch' , I do know and use these zones for circuit conductors…but turn me over and call me Susan woopy bloody do, If I put a bonding conductor at 155mm from a corner or vertically down the wall without mechanical protection and less than 50mm deep, without going through an accessory I must be an insane DIYer…but point taken Malcom I should think before opening my big gob.

Thanks for the welcome back lads it's always good to be back on here.

To be honest Johnny did have a valid point and yes though the bonding conductor is a cable how can you use a part of reg 522.6.100 to protect it??

The regs are guides and there are very few of them that is totaly black or white yes or no, most are open to various interpretations.

IMO bonding cables should not be buried for the reasons given by the OP in post # 23, but if you do want to bury them then I'm afraid then yes you will need to protect them as per the regulations, because if you didn't and someone damaged the cable in the future, unlike a circuit cable damage where you could get a short and a circuit blow, or worse still a direct contact shock, you would not know the cable was damaged until something very serious could happen

I have rarely seen in my time a bonding cables buried in a wall, yes often they are run under the floor but there is not the same stringent criteria to the regs for this as there is in cable buried.

Bottom line for me don't bury it
