Schedule of results when adding to installation

[n180]

When adding just a couple of circuits to an existing installation, what exactly do you put on the schedule of results with regards to the old circuits.

Just the circuit number and name or do you add the breaker details also like bsen, type, breaking capacity, rating. Obviously can't add ref method as you didn't do install so don't know all the details, but what about conductor sizes you can see inside CU?

Thanks.

One place to exercise caution when existing circuits go onto a schedule is number of points. Best to put N/V as it can be very difficult to accurately put a number to it. I was once on the receiving end of a complaint after various alterations to various existing circuits in an extremely cluttered house where much was inaccessible. A couple of years later new owners complained that my cert said X number of points when in fact there were Y number of points. A lesson learnt although I doubt many people would get quite as ---- over the number of points recorded on a cert as these people did.

The world's full of knobs!

It also can be very difficult on an eicr which I do try and put a number of points as accurately as I can but I’ve been known to use n/v as well, rightly or wrongly but there it is.

Just fill in the description of works that you have undertaken eg additional socket outlets to downstairs ring main circuit to the extension. Then fill in only the circuit(s) you have worked on. The circuit chart at the consumer unit/D.B. also needs updating. Always try to get copies of previous electrical certificates.
