RCBO’s used in a consumer unit in place of RCD’s – Image courtesy of the BS7671 18th Edition Wiring Regulations High Integrity Consumer Unit / Three-way Split Consumer Unit What this seems to suggest is that, although it isn’t at present, may be at some point in the future, split load boards may be deemed non-compliant and will need to be changed. This is something to bear in mind. This type of consumer unit layout has really emerged in recent years in response to the nuisance tripping addition to the wiring regulations. It essentially removes the use of RCD’s to create a split load board with RCBO’s (Residual Current Breaker with Over-Current) now taking their place. Most modern fuse boxes contain circuit breakers. It is possible to replace an old-style fuse box with a newer, safer version.

The most common enclosure is the standard surface mounted, metal, 'Amendment 3',enclosure. All four types of consumer unit are most commonly supplied in this format. They usually always feature a front lid hinged at the top, so that it closes through gravity when not being worked on, thus ensuring it is always closed. Width is dependent on the number of circuits, but they are usually about 240mm high and 110mm deep. Once the safety side of the board is in place, the next items to be installed are the MCB’s, one for each required circuit.Once all the testing has been completed the next job is to isolate the power to the existing fuse/circuit board and then remove it. We have multiple Design ranges to offer flexibility to the installer. The Design 10 board is suitable for all applications. As with all models in the range, there is ample cable space available even when RCBOs are fitted. The top mounted terminal rail makes the wiring of the neutral and earth connections neat and simple. Multiple fixing points, and a full metal DIN rail ensure the devices sit square. Design 30 is our enhanced consumer unit, created to be more aesthetically pleasing whilst including extra features to ease installation. Design 30 comes with a cable clamp installed and rear cable entry plate supplied, which allows for incoming meter tails to be safely secured.

Note: Depending on what the circuit will be running will depend on what size MCB is installed. Again, your electrician will know exactly what MCB can be used for a given circuit.Also you should be aware that some years ago, the standard wire colours used in the UK were changed so that they harmonised with those used in Europe so you may have several different colours of wire in your home. See our wire colours project here for more information. In summary, Hager consumer units offer a range of features that make them a popular choice for electrical installations. They are designed for safety, ease of installation, versatility, and long-lasting performance. One final point – If you still have an old style fuse box as opposed to a consumer unit, then this almost certainly won’t be compliant with the latest wiring and electrical regulations so you should think about getting it changed for a much safer modern consumer unit as soon as you can. The Consumer Unit – What is it? Aesthetically pleasing: Hager consumer units are available in a range of finishes, including white, metal, and chrome, to blend in with the decor of the building. The 18th edition was released in January 2019 and introduced a number of changes to the wiring regulations.
