Evening all.

I replaced a CU in a friends house the other week, completed EIC cert and all is good. He now wants his garage supplied with some electrics, no problems as i am going to use a spare way in the CU, use SWA supply to the Garage, install a small board in garage for lights sockets.

I am going to issue a EIC for his garage electrics but i'm not 100% certain how to do it.

I take it the 'Supply Characteristics' part refering to the main incomer?
What do you put in the 'Particulars of Installation Referred to in the Certificate'? - Is this house CU information?
Is the 'Schedule of Inspections' solely interested in the Garage install?

I'm still getting to grips with this game so any help is appreciated.

Cheers

Quite common problem on the industrial sector: cu is being fed from another cu.
i don't know whether my method is ok, I treat each cu as a stand alone but fed from the same supply.

Why is a DB feeding another DB via a sub-mains a problem ?
Testing is the same as any other final circuit.

I was looking on here for an answer, couldn't find it, thought i'd ask. If no one can help i'll just call them up.

The usual way I do this (others may have a different method),

Is to include the sub main (the supply cable) as one final circuit on the main CU/DB SoI and SoTR, including the (R1+R2) results etc. of the sub main.

Issue a second set of SoI and SoTR and EIC for the garage installation, using Zdb previously obtained for the submain above, and include the test results of the garage CU/DB and circuits on the second EIC and SoTR.

In answer to our question , this is how i would do the certs ,

Fill out 1 EIC for the swa feed to the garage and the lights / sockets / CU in the garage but use 2 test schedules
schedule 1 just for the swa submains from the main CU and schedule 2 for the garage CU and the lights / sockets that it supplies.

Sounds good, but if the house already has the Cert for the CU where your going to utilise a spare way is it ok just to add the extra test results for the new cable to that SoTR?

Simply do an EIC for the "main" DB, noting "used" against all the existing circuits. Fill out the details and results for the new circuit along with the obligatory Ze, bonding, etc etc.

Seperate EIC for the sub DB. Notitfy LABC

Am i right in saying the householder will now have 3 seperate EICs? An original one for the house CU, a second one for the installation of the new cable and a third one for the garage install?

If it was just done by you recently, you could do a quick check to see if anything has changed significantly (which it shouldn't have), and either as Murdoch said, fill out a new EIC,SoTR etc. as his post suggests, or add the sub main to the existing one if you haven't put a line through all the unused sections.

You include the supply charecteristics of the origin on the main CU/DB EIC, SoTR and SoI, as you would normally do, and put your Zdb of the sub main (as I said earlier) as the supply characteristics on the second set of paperwork.

If you had done the work altogether it could have been done under one EIC, with two sets of SoI's and SoTR's, one for each seperate CU.

So he'll end up with 3 EIC 's ? one for the main CU that he did previously , one for the garage submains that has now been added , one for the garage Cu ?
Im literally chewing my face off reading this.

Yes , and its completely un-necessary

Yes he would, based on the 2 jobs being done on seperate occassions plus 2 sets of LABC notification fees too.

Now, if the CU change is very recent, it could be argued that the original EIC could be updated to add in the extra circuit, BUT if the CU notification has been done he'll have to do a 2nd notification so a 2nd & 3rd EIC make sense.

I use PIRform and you can "copy" a cert so my "way" is so easy to do!

you already have one completed EIC for your original work , that cant be changed so put it to one side.
the rest of the planned work can be recorded on 1 extra EIC with 2 test schedules.
christ almighty.

I'm now getting lost here guys, looks like i'll be charging more to fill out Certs than for doing the actual job.

I was thinking of producing a new EIC for the installation of the sub main and adding a second SoTR for the garage. If it's wrong then i'll hold my hand up.

Depends on if it has already been notified or not, often if I know there is additional work to do, with the CU change as a prelude, I will hold back the paperwork until the job is finished, although I will not hold it back for months and months on end.

Am i missing something here ???
What has notification got to do with how you write out your certs ?? they completely seperate issues.
And Murdoch you cant add to the original cert once its been signed and dated even if your test software allows you to do so.

No, not really,

If the job has already been notified, then you have no choice but to issue another EIC, but this will include two sets of SoI's and two sets of SoTR's (although you may be able to use one SoI for the lot), as Biff said.

You need two sets of SoTR's as you have two different installs, with two different supply characteristics, if this makes sense.

Bloody difficult to word on a forum!

Because, if it has not gone through (notified yet), he can notify it all as one job, hence under One EIC, when you notify you have to put the description and extent of the work, this can all be included together.

The original Cert for replacing the CU has been signed off and notified.

I'll be able to produce a new EIC solely for the installation of the sub main. I will then add a second sheet of test results for the installed components in the garage from the second board.

If this isn't acceptable can you please explain why?

Sorry gents - you must be sick of this by now!

As an example Biff,

If I fit a new CU one week, and I know for definate there is a shower to fit the week after, then I will not finalise the paperwork or notify it until the Job is finished, this is common sense, it saves duplicate paperwork and two notifications and attendant fees.

Go with what biff55 says in my opinion.

Alot of the other posts seem to be a brain storming session going on leading to some confusion allround.
