Peter Monsen asks whether he must prepare a second EICR – one for the house and another for the garage. His question has been answered by the NICEIC (Theme – Regulations & Legislation):
Question: I'm in the middle of completing a re-wire, and the client requires a garage distribution board feeding one 20A radial circuit for socket outlets and one 6A lighting circuit.
My question is - when completing a domestic test certificate (EICR), do I have to write another for the garage distribution board that is being supplied from a 40A MCB with an 80A RCD mains switch from the main consumer unit of the house?
Answer: An EICR can be provided for the complete installation. However, a separate test results page must be completed for each distribution board, and it must be clearly marked to indicate that the garage board is fed from a sub-main from the house consumer unit.
If you refer to the NICEIC's Inspection, Testing and Certification handbook, it gives guidance on this issue.
