distribution circuit from house CU to adjoining Garage DB2 EIC details?

[gmdaly]

Hi, I have completed a EIC for a garage DB2 with five final circuits (no problem there i think). But for the distribution circuit from house DB1 to Garage DB2 I have completed a second EIC for this alone. The questions I have for the distribution circuit alone are:

1) For the EIC 'particulars of the installation' part where it wants 'max demand' should I include the demand of the main consumer unit DB1 or the demand of both DB1 (~35A) and the demand for the new installation of DB2 in the garage/workshop (27A). While im on this bit, should the DB2 garage installation max demand EIC record just the garage demand or the sum of both DB1 and the DB2.

2) For the EIC for the distribution circuit between DB1 and DB2 only: do I fill in the additional protection section of the EIC with NA for supplementary bonding and RCD (as its in a non RCD protected spare way with a MCB 63A in DB1). I am thinking that neither the supplementary bonding nor the RCD bit to the distribution circuit apply so I should put in NA?.

Thanks all. This is for a examined design project. Help much appreciated.

You only need 1 EIC with 2 schedule of test results.

Particulars of the installation as you would normally on the EIC.

Schedule of test 1 with the distribution circuit for DB 2.

Schedule of test 2 for the 5 final circuits supplied from DB2
