Garage Consumer Unit IP65 4 Way Fuse Box Fitted with RCD 63amp 30ma + 1X6amp, 2X20amp & 1X32amp mcbs

Product Information

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. 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.

Residual Current Devices (RCD): Like circuit breaker supervisors (CBS), RCDs typically cover half of your home each and will also cut out the electricity if the current rises too high In pretty much every other configuration they are a required feature for each and every individual circuit. is simply a trade term given to any consumer unit below four way - but usually, just two ways - commonly used in outhouses, sheds, and garages, where a couple of circuits may be required for lighting and tools. When it comes to a modern split consumer unit, the use of RCDs is necessary for 2 reasons to meet the wiring regulations.In this guide we take a look at the consumer unit and how it works, read on to find out more. Rules and Regulations for Electricity in Your Home The third and final circuit(s) basically sit next to the main switch and are comprised of individual RCBO’s that provide all the protection for the circuit they are supplying. These circuits are considered highly important and as they are individually protected and outside of the RCD circuits, won’t trip with the other circuits protected under them.

As we are discussing the two terms ‘fuse box’ and ‘consumer unit’, it can be confusing what these actually mean. If an intumescent strip is used for fire sealing, they must not be used inside of our boards. Taken from instructions. Tests on Hager consumer units have indicated that there is no specific need for external fire rated cable glands or intumescent sealing in addition to the guidance below, with respect to achieving a non-combustible enclosure. However, this does not preclude the designer/installer from using fire rated cable glands or external intumescent sealing should they consider necessary. To conclude, internal intumescent pads shall not be used. With the rising number of electric vehicles available, manufacturers have had to provide new ways of protecting both the user and vehicles. As such companies such as FuseBox have released standalone EV distribution units that can be added to new and existing properties. These units are most commonly supplied with a 100A Main Switch Isolator,Type A Double pole RCBO with or without Type 2 Surge Protection. Many electricians consider this the best circuit protection solution as each circuit is protected from overload and earth leakageindividually, thus preventing nuisance tripping caused by earth leakage on other circuits.Just as a matter of interest, DIN stands for Deutsche Industrie Norm and, originating in Germany, is any of a series of technical standards, used internationally, to designate electrical connections, film speeds and paper sizes. What are the Different Types of Consumer Unit? 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. An 'RCD Incomer' consumer unit is a special type of protection device, generally used in workshops, garages, garden offices, and sheds that use small numbers of circuits. Isolates the entire consumer unit and all devices. Turning this switch to 'OFF' will cut power to all circuits that are terminated in the consumer unit - which is usually all circuits in the house. Nearly all consumer units are supplied with a 100a main switch. Type 2 surge protection devices, also known as "secondary protection devices," are installed downstream from the Type 1 SPDs and protect against the smaller surges that may pass through the Type 1 SPDs. They are typically installed at the distribution board or sub-distribution board level and have a lower discharge capacity than Type 1 SPDs, typically ranging from 10 to 40 kA.

Location and Accessibility: Consumer units should be installed in a location that is easily accessible for maintenance and inspection. They should not be located in bathrooms, shower rooms, or similar spaces unless there is no other suitable location. RCD’s also work by detecting an imbalance between the Live and the Neutral conductors and this feature is a requirement for all Class 2 double insulated equipment. Type of consumer unit: As we discovered in the previous section, there are a wide variety of different types of consumer unit, each priced differently It is a good idea to have an electrical inspection if the wiring in your home is old or you have specific concerns over whether it is safe or damaged. What is the cost of replacing an electrical consumer unit?

Hager consumer units have a range of features that make them a popular choice for electrical installations. Some of the features of Hager consumer units include: The RCD is then clipped onto the DIN bar. The top clip is first clipped over the top of the bar and then bottom either clips over using a spring clip, a screw or simply just clips over. Connection Integrity: All connections within the consumer unit should be secure, properly terminated, and free from any signs of overheating or damage.

Circuit breakers: Each circuit breaker is assigned to a certain area of your home electrics, e.g. the upstairs lighting. When the circuit is overloaded (too many electrical items are connected) or if the current reaches excessive heights, the circuit breaker cuts the power to prevent electrical fires Although used in most types of consumer unit setup, they are not required for those with RCBO’s as these do exactly the same job but with additional safety features. High Integrity consumer units are becoming increasingly popular with electricians - becausethey make circuit design easy - and homeowners - because they offer excellent protection without breaking the bank. They are particularly good in projects requiring 12 or more circuits. Fire Resistance: The enclosure of the consumer unit should provide adequate fire resistance to contain any potential fire within the unit and prevent it from spreading. Flush consumer units are one which is recessed into the wall. All four main consumer unit types are available in flush versions. They are functionally the same as a standard amendment 3 enclosure but are aesthetically better with a very slim profile.Read on to discover more about fuse boxes and consumer units, essential factors to consider and the cost of replacing a fuse box with a consumer unit. Cost of replacing fuse box with consumer unit Finally, you may wish to upgrade your fuse box or consumer unit to a larger capacity model, more able to cope with extra demand if you are extending your home. Arc Faults are where, if the current is high enough, electrical currents jump the gap between two conductive materials. Arcs can reach temperatures of up to 6000 degrees and can be the source of over half of the domestic house fires in the UK. Reasons for this include damaged cables from rodent damage, degradation, crushed cables, loose connections, and more. AFDDs are likely to become mandatory in the future as further protection against fires caused by faulty domestic wiring.
