Question: What is the maximum number of double sockets that I can put on a radial circuit having 4mm twin and earth looped cable on a 20A RCBO?
Answer: Appendix 15, Fig.15B refers to radial circuits.
There is – in effect - no limitation as to the maximum number of double sockets that can be added, as this would need to be ascertained at the design stage of the radial circuit when the loading is calculated.
If a radial circuit has been adequately designed, then no issue of overload and nuisance tripping would exist.
