Consumer Unit Arrangements
Option 2
Split Load Twin RCCB plus Dedicated RCBO
This arrangement provides a dedicated 30mA RCBO for the smoke
detector circuit, but 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
limiting the number of circuits affected.
