This Question of the Month, concerning final circuit supply, is answered by ETCI:

Question: How many points should a final circuit in a domestic premises supply?

Answer: This depends whether the circuits are radial or ring final circuits.

For a radial circuit the maximum number of points recommended is 10 per circuit. This applies to either lighting circuits or socket outlets etc. In the case of socket outlets a twin socket outlet would count as one point. For final socket circuits it is recommended that a radial circuit should not serve more than two rooms.

For ring final circuits the number of points is unlimited within a floor area of 100 sq. meters.
