Product Information

Again, it entirely depends on your existing electrical layout as to how this is done, but your electrician will certainly know.

Newer and safer, consumer units also break the electrical circuit if the power in the home rises too high. 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. Condition of old unit: When replacing a fuse box or consumer unit you may be charged a fee to remove the old unit. This charge may increase if the old unit is in poor condition If this is a new consumer unit install for an existing property then your electrician will have either marked each circuit to identify what it powers or will work each one out as he gets to it. A ' Main Switch Consumer Unit' is so called because it is supplied empty of all protection devices except the main switch. Whilst it may be populated with an RCD and MCBs.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.

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. 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. RCD’s can also be switched off manually and can take the place of the isolator switch in the consumer unit, if they break live and neutral. The Consumer Unit or fuse board is the most important electrical safety device in the home and workplace. It fulfills two vital functions: Overcurrent Protection: Consumer units should incorporate suitable overcurrent protection devices (fuses or circuit breakers) for each circuit. The rating of these devices should be selected based on the current-carrying capacity of the cables and the load they serve.

This seems to suggest that moving forward, RCBO’s should be used for individual final circuits as opposed to RCD’s as the earth leakage across several appliances on the same RCD could be enough to tip the balance and cause nuisance tripping, especially where washing machines, dishwashers and the similar that can earth leak quite a bit, up to 5mA in some cases are featured. 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. Allowing for the use of RCBOsand two banks of MCBsthey offer total circuit separation for critical circuits and highly cost effective protection for standard circuits.

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.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. 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.

Cable Entry and Exit: The consumer unit should have suitable cable entry and exit points with proper cable gland or entry system to maintain the ingress protection rating and prevent damage to cables. Clear Labeling: All circuits within the consumer unit should be clearly labeled to indicate their purpose or the area they serve. This labeling is important for safe operation, maintenance, and troubleshooting. When it comes down to it, the only person(s) able to do this are those that are Part P registered. If however you ignore this and do carry out electrical work that you’re not allowed to, this is illegal and also can invalidate your home insurance and cause potential issues when trying to sell your home. The image below is of what’s known as a split load board. This is where it features a main switch for the entire board plus at least 1 RCD labeled as “E”.

This guide features the various costs associated with replacing fuse boxes and consumer units that they provided. The modern consumer unit also has a range of other safety features including a main switch that controls the power to the entire unit, that, once switched off, will turn the power off to the entire house.
