Eaton Memera Single Pole “B” Type EAD Range RCBO 6-45A 30mA
The Memera consumer units use MCBs and RCBOs for final sub circuit protection and can also accommodate a wide range of command and control devices such as timers, contactors and relays.
The new range of full metal consumer units provide a suite of products to meet the requirements of BS7671:2008 17th Edition IET wiring regulations amendment 3:2015.
Regulation 421.1.201 has been introduced to contain a fire should one develop within a consumer unit, the fire igniting primarily as a result of poorly installed connections or faulty installed components. It requires that within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and must have their enclosure manufactured from non-combustible material. Otherwise, it should be enclosed within a cabinet or enclosure constructed of non-combustible material.
This regulation effectively requires the use of a full metal consumer unit with the complete enclosure, i.e. the base, cover and door made from steel and will ultimately affect all new and rewired installations in homes referred to as ‘domestic (household) premises’ which will include integral / attached garages and outbuildings in close proximity.
Amendment 3 published in January 2015 will become effective on new and rewired installations designed after 30th June 2015, however clause 421.1.201 will have the later implementation date of 1st January 2016, although it does not preclude it being applied before then.
