New Garage Supply Certs

[Thomps]

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

Have you asked your schemes technical support?

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.
