supplementary bonding

[nicks electrix]

Evening All,

I have been asked to change a normal light in the bathroom to LV,IP RATED spotlights.The bathroom fitters have already fitted the bathroom and so i asked if they had done any supplementary bonding and they said no, their sparky told them for the last year that bathrooms do not need it. So i argued the fact that it can only be omitted if all 3 conditions are met. They still wont have it.

Is it my duty to ensure that it is fitted if i was to fit the downlights or do i note it on the MW Certificate?

If the spotlights are fire rated do i need fire hoods?

THANKS

Is there 30mA RCD protection on all circuits and are all incoming services (ie, Gas, water, oil) bonded to the MET with correctly sized (usually 10mm) MEBC's ?. If yes then I would say no supplementary bonding needed as the method of fault protection is ADS and not EEBADS.

i have been looking into this for a job im doing.

Apparently if all the three conditions in the 17th are met then its ok AFAIK.

I was wondering if some people add supplementary bonding anyway to give it the old "belt and braces" treatment.

Fire rated downlights won't need hoods.

Page 2, under Supplementary Bonding, last sentence.

As there is no Supp Bonding, it would be best for you to install RCD protection (RCBOs?) to all circuits of the location and check Main Bonding is up to scratch.

If the customer baulks show them the leaflet. If they say anything along the lines of "the bathroom fitters said..." give them the NICs, ELECSAs and NAPITs helpline numbers and suggest they call them. Tell them to call you back once they're satisfied you're not bulling them up.

if they said that to me, i would then start giving them advice on their bathroom...

Also, if you're extending the circuit to fit the lights (which you must, by necessity) then you will need to RCD protect them anyway.

answered in post 2 - if all conditions are met, then no need to supp bond

 

[PC Electrics]

:^O :ApplaudMy question remains though, because i am doing work on the lights do i need to install supp bonding or just note it in the cert?

Seems to me that your question has been answered. Perhaps you could clarify where your uncertainty lies?

 

[nicks electrix]

OK let me try to explain the question better,

If all of the conditions are not met for supp bonding to be omitted and i do the alteration to the bathroom lights is it down to me to install the supp bonding or do i not do it and note it on the MW certificate that there is no supp bonding in bathroom.

I HOPE YOUS UNDERSTAND.

 

[Andy™]

if conditions are not met, then you will need to supp bond

Access not easy and metal bath which makes it a nightmare. Never seen the legrand clamps are they any different?

 

[paul b b]

fair enough if acsess is bad, can you megger the bath to see if its exte or not?

the legrand clamps are a quick fit thing, they say 10 secs to fit 1

 

[nicks electrix]

I will give it a try.

I got to get some of them clamps i will try and google them see what they look like.
