Consumer Unit Arrangements
Option 3
Split Load 3 RCCB Board
This arrangement provides a 30mA RCCB for the smoke detector
circuit which could also supply other circuits e.g. lighting, and
combines the rest of the circuits across two further 30mA
RCCB’s. Careful arrangements of the circuits can reduce the
likelihood of nuisance tripping, thereby limiting the inconvenience
or potential hazards that a loss of supply can cause by reducing the
number of circuits affected.
An example is shown over page.
