Consumer unit solutions
There are many ways of providing RCD circuit protection to meet the demands of the new regulations.
The most comprehensive solution would be to provide individual RCBO protection on each
and every out going circuit from a consumer unit. Hence the use of a consumer unit such as a
12 way isolator controlled board. eg.
EAD12
fitted with up to
12 x RCBOs
or the
EAD11R
11
way unit with additional cabling space to accommodate the RCBOs.
The next level down would be to provide an isolator controlled dual RCD consumer unit
feeding two RCD board sections. eg.
EAD12H80H80D or EAD12H80H63D
fitted with up to
12 x MCBs
Such a dual RCD board could also be provided with some unprotected ways controlled by the
main switch to enable a supply to any individual circuits that don’t require RCD protection or
else require individual RCBO circuit protection.eg.
EAD12H80H803D or EAD12H80H633D
fitted with up to
15 x MCBs
A conventional split load board such as an
EAD14H80D
could have additional RCBOs fitted
to the non protected side allowing a mixture of Group RCD protected circuits and Individual
RCBO protected circuits.
Consumer units are already available with RCD incomers of 30mA sensitivity such as
EAD12H80, EAD12H100
. However, single RCD controlled units on their own are unlikely to
satisfy regulation 314.1 and 2.
