NM Consumer Units
for use in Domestic
Household Premises
Amendment No. 3 BS 7671
CONSUMER UNITS FOR USE IN DO
REGULATION 421.1.201
17th Edition Wiring Regulations Incor
From January 2015 Amendment No. 3 to BS 7671
IET Wiring Regulations prescribe that within
domestic (household) premises, consumer units and
similar switchgear assemblies shall have their
enclosures manufactured from non combustible
material, or be enclosed in a cabinet or enclosure
constructed of non combustible material and comply
with product standard BS EN 61439-3.
What are Domestic Household Premises ?
Typical Domestic household premises would include single and
multiple occupancy homes such as Houses, Bungalows, High Rise &
Low Rise Flats, Apartments, Student lets, Sheltered
Accommodation, Farmhouses, Houseboats, Static Homes, Home
Office, attached Garages, Workshops and Detached
Summerhouses etc.
What is Non Combustible Material ?
There are many types of non combustible material however,
amendment 3 of the 17th Edition regulations provides an
acceptable example as ferrous metal i.e. Steel Consumer Units.
What is an Enclosure ?
The consumer unit enclosure must be manufactured from a non
combustible material so as to limit the spread of fire. An
enclosure means the box, cover, door, hinges, handle and any
components required to maintain the integrity of the unit.
What is Similar Switchgear ?
Similar switchgear is switchgear that is used for the same
fundamental application ie. a circuit protection assembly with two
pole isolator and one or more circuit protection devices, e.g. MCB
distribution board, fuse switch, garage unit or PV switchgear etc.
What are Cabinets ?
Typical cabinets are meter cabinets that are normally built into the
fabric of the building and that may or may not include consumer
units within. If the cabinet is of an all metal construction (noncombustible), then a standard skeleton consumer unit (FAL) can
be installed within. If the cabinet is of a combustible material, a
metal consumer unit is required.
What about Cable Entry ?
As usual good workmanship and proper materials should be
applied to all installation work, consumer units must be installed
to achieve IP4X on the top elevation (regulation 416.2.2) and
IP2XC on all other elevations. This can be achieved by use of cable
entry accessories such as consumer unit pattrass or other means
such as glanding.
This guide to Wylex consumer units is not a suitable substitute for the standards and regulations that should always be used for all types of electrical installation design & installation work.
OMESTIC HOUSEHOLD PREMISES
rporating Amendment No. 3 : 2015
l All metal enclosure, no
external plastic parts
l Low Smoke & Fume paint
l Non combustible cover blanks
l Compact enclosure
l Available in ‘no miss terminal’ fixed
busbar versions and flexible
versions
l Raised & removable DIN rail /
busbar assembly
l Cable entry knockouts on 5 sides,
top, bottom, left, right and rear
l Mains tails cable entry grommet /
gland for supplementary insulation
similar to Class II level of
protection to mains tails
l Time delay RCD available for
TT systems
l Up to 38 way units, all designs Main
Switch, High Integrity, Split Load,
Dual RCD
l RoHS compliant in excess of
UK standards
l UKAS certified to BS EN 61439-3
What about Cable Entry ?
The IET on site guide also recommends that where metal consumer units are installed into TT systems the mains tails are protected
against the possibility of becoming loose and making contact with the metal enclosure by incorporating into the installation 100mA
time delayed (S type) RCCB protection.
Furthermore in all cases (including TT) the mains tails should be protected at the point of entry into the metal enclosure e.g. by use
of a mains tails gland to protect against the possibility of mechanical damage and or disturbance that could lead to tails becoming
loose and making contact with the metal enclosure.
CONSUMER UNITS FOR USE IN DOMESTIC HOUSEHOLD PREMISES
17th Edition Wiring Regulations Including Amendment No. 3
17th Edition Wiring Regulations Including Amendment No. 3
Amendment No3 has brought about the requirement for ‘all metal’ non combustible enclosures for consumer units and similar switchgear.
This is in addition to the requirements for Additional Protection (30mA RCD) as summarised below. Within domestic household premises.
l Installations should be divided up into circuits so as to take account
l All socket outlets should be protected by 30mA RCD
of danger and inconvenience caused by a single fault - e.g. such as a
l All circuits serving or passing through a room with a fixed bath or
lighting circuit***
shower should be protected by one or more 30mA RCDs**
l All cables buried beneath the plaster surface of the wall or partition l Installations should be designed and arranged so as to prevent
unwanted tripping of RCDs***
(at less than 50mm) should be protected by 30mA RCDs***
l
Safety services such as smoke alarms should be on independent
l All cables concealed in metal stud partitions (common in new
circuits****
builds) should be protected by 30mA RCDs***
l Installed units must be to IP4X on top elevation & IP2XC elsewhere

A The IET on site guide also recommends that where metal consumer units are installed into TT systems the mains tails are protected against the
possibility of becoming loose and making contact with the metal enclosure by incorporating into the installation a 100mA time delayed (S type)
RCCB protection.
B Furthermore in all cases the mains tails should be protected at the point of entry into the metal enclosure by use of a mains tails gland to protect
against the possibility of mechanical damage and or disturbance that could lead to tails becoming loose and making contact with the metal
enclosure.

Regulation 411.3.3 socket outlets with a rated current not exceeding 20A.
Regulation 701.411.3.3 Additional protection shall be provided for all circuits of the location by use of one or more 30mA RCD.
Regulations in the 522.6.200 series cables concealed in a wall or partition at less than 50mm depth and without earthed mechanical protection
e.g. conduit.
**** Regulation 314.1 Every installation shall be divided into circuits as necessary to avoid danger and inconvenience in the event of a fault, take
account of danger that may arise from the failure of a single circuit such as a lighting circuit, reduce the possibility of unwanted tripping of RCDs
etc.
**** Regulation 314.2 Separate circuits to be provided for parts of the installation that need to be separately controlled in such a way that those
circuits are not affected by the failure of other circuits.
***** Regulation 560.7.1 Chapter 56 circuits for safety services shall be independent of other circuits.
In addition Chapter 51 requires designers/installers to take account of all relevant British Standards and manufacturers instructions. For example
BS5839 Part 6 is the British Standard for fire detection and alarm systems in dwellings. It states that power supplies to Grade D smoke alarms
should be an independent circuit at the consumer unit, or a separately electrically protected local lighting circuit.
****** Regulation 416.2.2 requires that the installed consumer unit achieves IP4X (1mm probe) on the top elevation. All other elevations should be
to IP2XC (2.5mm probe).

CUSTOM BUILT
To meet the ever changing requirements and
designs of the modern electrical installation,
Wylex offers a service to the electrical
installer for all the catalogued NM range of
products - Consumer Units, and Distribution
Boards to be modified and assembled to their
own particular specification and meeting
specific customer needs.
The levels of adaptation may vary from the
basic pre-population and assembly of outgoing
protective devices MCBs, RCBOs into the
units with personalised labelling, to the
complete customisation and wiring of
additional accessory devices within a unit:for example meters, energy monitors,
control switching equipment:- contactors,
relays and timers, and over voltage surge
protection devices plus almost any other
DIN rail mounted piece of electrical
accessory equipment that is available.
This Custom Built service can save time on
site, reduce labour costs, and help achieve
early completion & ultimately save money
for the installer of these units.

circuit protection and control devices fitted
