When learning to understand consumer units, also recognised as fuse boxes or electrical distribution boards, we must first understand that are replaced is because yours don’t have an RCD (Residual Current Device)
Why do I need an RCD?
A fuse box or a circuit breaker is designed to protect your installation and your assets. Visually, these are determined by the cable in the wall and the cooker at the end of it.
At Electric11, we install an RCD. They are far more sensitive under earth fault conditions so if you or a family member are receiving an electric shock the power trips off quickly before it causes injuries or disturbances to the property or the residents.
At Electric11, we ensure that all of our RCD’s are reliable and safe to install before installing all consumer units. The types of RCD’s we use typically range, and each has a separate purpose.
AFDD – Tier 1
AFDD, also recognised as Arch Fault Detection Device, is a brand new type of device that does all the jobs of a Fuse or Circuit Breaker, alongside the job of an RCD.
Plus, it can detect arching in circuits, which can cause fires if left unattended to.
These fires are often caused by poor installation or damaged wiring, and so installing new consumer units such as AFDD’s are important.
AFDD’s can be a significant upgrade for high ignition premises, such as thatched buildings for instance, where a fire risk is much more likely to cause significant damage to a property or residents.
RCBO – Tier 2
RCBO, also recognised as the Residual Current Breaker & Overload, is an RCD incorporated into a Circuit breaker.
The RCBO is a great new model for domestic properties as it directs attention towards electrical faults and electrical leaks.
However, it is less reliable at catching smaller sparks in comparison to the AFDD, and can therefore cause more potential fire hazards to the property or residents. Thatch roofed properties, for example, would be more inclined to need an AFDD.
The RCBO ensures every circuit has its own earth fault protection.
Dual RCD – Tier 3
With this fuse board, you get two RCD’s and several circuit breakers that provide electricity to your circuits, such as your sockets and lights.
This is fully compliant and regulated RCD which affords you the required level of protection that every property needs.
However, unlike an RCBO or AFDD, if an earth fault occurs on one circuit, it can affect all other circuits that are supplied by that RCD. With this issue, you will not be able to turn any circuits back on until the fault is resolved. If left unresolved, it can become hazardous to both the property and residents.
Here is an example of a Duel RCD Board installed by Electric11 in Norfolk.

More about us
What is a Consumer Unit?
Home consumer units, also known as fuse boxes, refer to the not a device that directly powers appliances, but rather a central system that distributes electricity and protects against electrical faults.
These are typically put in domestic locations such as houses or garages to ensure an even distribution of electricity around your property.

When replacing a consumer unit (fuse board), the “type of board” mainly refers to how each circuit is protected. We typically install a modern dual-RCD consumer unit and provide the required certification and building-control notification.
A dual-RCD board splits your circuits across two RCDs, so groups of circuits are protected together. This is a popular option for many homes because it’s a solid safety upgrade from older fuse boards and works well for most standard domestic installations.
Good for: typical homes where you want modern protection and clear compliance without over-specifying.
An RCBO combines RCD protection (shock protection) and overcurrent protection in a single device per circuit. That means if one circuit trips, it’s less likely to take other circuits down with it—often reducing nuisance trips and improving day-to-day reliability.
Good for: homes with higher electrical demand, sensitive equipment, or where you want better separation (common with EV chargers, home offices, renewables, etc.).

An SPD helps protect your home’s electrical system and connected electronics from transient overvoltages (surges), such as those caused by switching events on the network or nearby lightning activity. SPD selection and application is covered in guidance for complying with BS 7671 surge protection requirements.
Good for: most modern homes, especially where you have computers, smart home tech, EV charging, solar inverters, or battery storage.
AFDDs are designed to detect certain types of dangerous arc faults that standard protective devices may not pick up in the same way. They’re covered in BS 7671 guidance/fact sheets and may be considered for specific circuits or risk profiles.
If you’re interested in AFDD protection: ask us during your quote/survey and we’ll advise whether it’s appropriate for your property and which circuits it would apply to.
Not sure which board type is right for your Wymondham property? We’ll recommend the best-fit consumer unit setup after assessing your existing installation and future plans (EV charger, solar, battery storage, extensions).
Book your free quote todayDuring a consumer unit replacement, we normally need to isolate power to the property while we disconnect the old board, reconnect circuits, and complete safety testing.
Typical power-off time: often around 3–5 hours for many domestic replacements
Typical on-site time: commonly 4–8 hours in total, depending on the number of circuits and the condition of the existing installation
If we find pre-existing issues (for example, unsafe circuits that need attention before they can be reconnected), the job can take longer—however we’ll explain what’s been found and the safest way forward.
We confirm the plan, check access to the existing consumer unit, and run through any last details before starting.
We safely isolate the supply so we can work on the board and circuits.
We disconnect and remove the existing unit, keeping everything organised so circuits can be correctly reconnected and clearly labelled.
We fit the new consumer unit and reconnect circuits in a controlled, methodical way.
