Difference between RCD and RCBO Consumer Units
Are you considering a new consumer unit? If the answer is yes, then this blog is perfect for you! We explain the difference between RCD and RCBO mains boards, so you can ensure you're choosing the ones that's best for you. Any questions, don't hesitate to contact us here.
RCD protected dual split load consumer unit: Arranges circuits in two main sets controlled by separate RCDs. For example, RCD 1 may control everything upstairs and RCD 2 may control everything downstairs. If in the future, there is a fault on an RCD board, the power to all circuits controlled by the RCD will be disconnected (so a fault on a downstairs socket would result in all power downstairs being disconnected until the problem is resolved).
An RCBO provides the same fault protection as above, but for each individual circuit. This means that if a fault occurs, power will only be lost on the faulty circuit. This can be beneficial because it may allow you to continue using other circuits until the issue is resolved and it may be easier to diagnose the fault as it will be apparent immediately as to which circuit the fault has occurred on. **Note: This can be beneficial in such cases when power may trip out of hours (e.g. evenings and public holidays). With an RCBO board, it may give you the ability to manage until a more convenient time for an engineer to attend.
