what cert?

[shagg]

Hi guys

I'v got a shower job soon and not quite sure what cert to use, It's a shower change, like for like (7.5kw on a 6mm) I'm not changing the cable, And a plumber coming in to change the shower I'v just got to connect up and test. But I'v also got to upgrade the main bonding and pull in supplmenty bonding as there isn't any RCD protection. Any idears. MW or NEIC

Minor works!!

your not installing a new circuit only modifying one and making improvements to the earthing your fine!!

 

[Risteard]

Surely RCD protection is required.

I would agree you are working on the circuit so you take responsibility for it RCD I would say is required for this job

RCD should be fitted but if customer dont want one fitted what can you do..! the OP is going the right way about it though by installing supplementary and upgrading the main bonding

A Minor Electrical Installation Works Certificate certifies that the work complies with the Regulations.

Tell them to look at manufacturers installation instructions, they all now state must be protected by an RCD and installed to 17th edition etc etc.

EIC and notifiable. no other choice.

Look at it like this, if you fit it without RCD and the instructions say it should have one, then when it goes faulty you get the blame and cost even if its nothing to do with you, because it isnt installed to the manufacturers instructions.

If someone gets hurt and it needed a RCD, the customer will have forgotten the conversation regarding not having one fitted, so it will be your fault again. And if it requires RCD and doesnt have one then it is not compliant so you cant certify it.

You lose all ways up, and it may not just be money. For the sake of £30 put one in.

cheers guys for all your in put. I agree, I would alway put a shower circuit on an RCD, But like stated the bloke don't want the added cost and seeing that the cable isn't being changed there isn't a requirement to fit one.

I would disagree if you are a member of a competent person scheme you have agreed to work to the 17th edition which requires RCD protection section 5.3 page 62 of electricians guide to building regs.

States "Circuits supplying equipment in bath and shower locations must be protected by a 30mA RCD.

I would check with your competent person scheme and see what they say.

strictly speaking a like for like is maintenance and this does not need a cert. It would be good to do a minor works however since it confirms that the circuit protection should work.

a new install would require a rcd as stated in other posts and ideally the current circuit woudl be upgraded to include rcd protection (which would then require an installation cert and be notifiable).

the OP is doing all that is expected of him under the 17 edition bs7671 by upgrading the main bonding and installing supplementry bonding as a minimum. and that work would fall under a minor works cert.

at lease that is how i understand it and is confirmed by my prof body when i asked on a similar matter.

Hi all,
Interesting points, would go with the install RCD personally as per what the manufacturer would likely say in the instructions. Weird how Bs7671 are not mandatory but everyone will look to them when it goes wrong. i guess its a case of 'Rather what if than if only...

Best wishes

I personally would install RCD or walk away from job.

 

[pennywise]

I think I would be inclined to put it on an rcd considering that apart from the cooker it's the largest load in a house on the biggest breaker and in the most vinerable postion ie a wet cubical it's a no brainer I'm afraid.

Fit an RCD and use the instruction manual as a beating stick, then point out in the BRB that you work to manufacturers instructions..................

 

[Notsosmart]

Yep, Manufacturers instructions take precedence
