Why dual rcd consumer units

In this scenario a problem with the outdoor lights will only interrupt power to that circuit, leaving all other circuits - including the fridge freezer and oven - in operation.

Available in a number of sizes from 6 way to 16 way, these consumer units will suit most applications. Each unit has an integrated spirit level, aiding installing without additional tools. This range of all metal consumer units offer a flexible solution for the 18th Edition Wiring Regulation BS Available in a number of sizes from 8 way to 14 way, these consumer units will suit most applications. The terminal and busbar design provide maximum flexibility for a combination of protected and unprotected circuits.

A range of additional BG control devices can be fitted into the consumer units. SPDs are installed between the outside feed and the main switch in your consumer unit and will trip if any inward surge is detected. Arcs can reach temperatures of up to 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. Many electricians consider this the best circuit protection solution as each circuit is protected from overload and earth leakage individually , thus preventing nuisance tripping caused by earth leakage on other circuits.

See our range of main switch consumer units. Consideration must be given to circuit design in this scenario. You should not, for example put all the lighting circuits on the same RCD as an earth leakage fault on one of those circuits will cut power to the whole bank, leaving you without any lighting. Despite the limitations of dual RCD consumer units, they remain extremely popular due to the cost. Indeed, most 'fully loaded' consumer units are dual RCD configuration.

View our superb offers on fully loaded dual RCD boards. Allowing for the use of RCBOs and two banks of MCBs they offer total circuit separation for critical circuits and highly cost effective protection for standard circuits.

High Integrity consumer units are becoming increasingly popular with electricians - because they 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. See our range of high integrity consumer units. RCD Incomer Consumer Unit An 'RCD Incomer' consumer unit is a special type of protection device, generally used in workshops, garages, garden offices and sheds which use small numbers of circuits.

The defining difference between this and other types of consumer unit is the fact that it does not have a 'Main Switch'. Isolation of the board is handled by the single RCD.
