New Consumer Unit,what do you think ?

[Maccas]

Hi
I have been asked to quote for some remedial and extra works such as new gas bonding,new circuit for boiler supply,light and switch in loft,2 extra sockets in kitchen,shaver point in bathroom and change some socket and switch plates.
The customer had a EICR done about a year ago which was classed as unsatisfactory.
One of the faults was the entry hole for the tails being too big and that the tails being 16mm were too small.
The customer wants a certificate to say its all satisfactory when the work is all done.
I will be issuing a new EIC for the boiler circuit and minor works certs for the additional works.
Should I instead recommend a board change and EIC then the whole installation would be covered.
Ive attached a pic of the existing consumer unit,RCD 30ma from the 1980s I think.
Any views would be much appreciated.

And tested £300+a bit more say another £150

Why? Maccas already doing plenty of work in the property, A loaded RCBO board costs £150, couple of hours work to install. £150 profit. No need to rip off the customer.

 

[rolyberkin]

£150 profit, two hours work, have you been drinking?

I don't need the money I like to think I'm honest.

yeah, dick turnip!

Why are we discussing a new CU cost.

The cat was let out ...

That RCD is rated at 63A, not sure I would want a shower and cooker on it, along with immersion and everything else.

A C2 maybe, if was my job I would quote for the work that has been requested, and a new EICR afterwards, you could try and get RCBOs fitted and change the RCD for a Main Switch, but looking at the pics, that avenue may not be possible, if the hole for the tails is the only issue fit one of the tail entry glands.

No an eicr has been done and a report produced and paid for by the customer. All you need to do is produced an EIC with all jobs youve completed in section "extent of work covered by this certificate" and cross refrence the report number of the eicr already done. A headed letter attached is also advisable explaining this but not always necessary.

No customer will want to pay for retesting circuits that have allready had the all clear!!

You only need to replace the tails if supply fuse is 100amp

Why?

 

[telectrix]

Why?

coz it's written in tel's guide GN 007. "do what you want as long as the cheque clears before the fire".

using the rule of thumb...largest current rating and 40% of the remainder gives a maximum demand of 78A..The CCC of the 16mm tails is 87A....I don't see a problem.

 

[westward10]

ccc is 76A.

 

[Leesparkykent]

ccc is 76A.

If enclosed in conduit. https://www.dungannonelectrical.co.uk/dun1-shop/pdf/cable/6181Y.pdf
87A if clipped direct.

 

[westward10]

That is correct Lee, 76A which allows for containment within the consumer unit where it cannot be considered clipped direct.
