Am I right or wrong?! Bonding question!

[ben2012]

I was always under the impression that you no longer had to bond across the pipes or to a metal sink in a kitchen providing all local circuits were on 30ma rcd. But a lad at work has had me doing it today saying as its not classed as a special location it had to be done? I've looked through the regs but cannot find anything to say either way. Any suggestions? Thanks

To bond or not to bond............that's a good question

Are they extraneous?

 

[shocking_eg]

your right.

 

[ben2012]

Where does it state it in the regs though?? Thanks

 

[BillyH]

Even in the 17th edition, it still doesn't have to be bonded

The regs won't tell you what doesn't need to be done

 

[ben2012]

Sorry to be a pain but I'm wanting some firm 'evidence' either way? Just so I can show him! Thanks

just let him carry on wasting time and money lol

 

[ben2012]

Well I think I'm just going to ask him where it says you need to do it, as I can't prove it either way! Thanks for the replies.

Cross bonding can be omitted as long as the installation meets the current regs and disconnection times

 

[ben2012]

Thanks for that chris, I'm just really wanting to know where it states this in the regs? Thanks

Well have a look in the regs then, you will find all the information regarding this in there.

on a schedule of inspections theres 2 boxes....supplementary bonding and/or RCD....
you cannot ommit both

 

[brucelee]

or look in OSG 4.6 old red OSG and 4.7 new green osg
Additional protection- supplementary equipotential bonding 415.2
says supp bonding may be required in some areas

If the installation meets the requirements for earthing and bonding then there is no specific requirements in BS7671 for supp equip bonding of

Kitchen pipes , sinks or draining boards
metallic boilerwork
metal furniture in kitchens
metallic pipes to hand basins and WCs
locations containing bathrooms providing the requiremnts of 701.415.2 are met

If you have main protective bonding in place in accordance with reg 411.3.2.1
all circuits comply with requirements for ADS according to 411.3.2
all final circuits have additional protection by rcd 30mA
then there is no requirement to install supplementary equipotential bonding in a bathroom

metallic waste pipes in contact with earth must be bonded to the MET see also 4.3 osg

Or if your an old git like me you can bond them whether there is RCD or not
No harm..............at all IMO.

No need to bond the aluminium greenhouse though...........it's outside the 'zone' and very near to a PD called 'true earth' lol.
Could be very dangerous !!!
