ELECTRICAL INSTALLATION CERTIFICATES

[Deleted member 138473]

Hi

When filling out EIC forms under a few sections (design, construction) it asks to fill in the empty line with dates for an amendment of BS7671:2018.

Will this date be 2020 now as the first amendment has been released.

I was told to N/A this part by a tutor.

Thanks.

N/A.

Are you sure, when you click on that option it actually brings up 2020

 

[telectrix]

my forms still say BS7671 1991. note to self...must get up to date, ??

It should read BS7671:2018, Amendment 1:2020

1st February 2020, applicable immediately.

Tutor is wrong

It's BS 7671:2018 (2020) so insert for "amended to" as "2020".

The NICEIC are also thinking of making the filling in of Certs easy & less information required, this will help because on certain areas you are always doubting yourself, with a lot of LIM N/A items.

A question on disconnection times for new distribution circuits.

I have been pulled up by the NIC for not proving to meeting disconnection times on two different certificates, highlighted below.

The single phase circuit is from a TN system and supplies a converted bus using a TT system. The cable has had the SWA and CPC isolated in an insulated box, using only the local earth stakes and bonding.

The 3 phase circuit is from a TN DB to a new DB in the same building.

From the NIC - "provide evidence showing that the two Sub mains circuits installed at the two sites attended meet disconnection time stated in regulation 411.3.2.3 and 411.3.2.4"

The below apparently does not satisfy the requirement, and I'm just not seeing the issue.

Any help greatly appreciated.

Perhaps they want to see your design calcs although if the figures used are from the BBB or OSG no lengthy design calcs should be necessary!
May have to ask your inspector to be more specific!

Agreed, max figures are from 7671. Just needed to check that I haven't gone 'Cert blind' from staring at it for so long.

Were they expecting to see the 80% figure of 0.69 ohms in the max permitted box?
The 2nd one is a tad close but within it.
Looking at the 2nd certificate, the other thing that might be viewed as suspicious is that by deduction the first two circuits suggest a Ze of 0.21 ish ohms and the 3 phase circuit suggests a Ze of 0.52 ohms. Something doesn't quite add up?
