FEATURE
fundamental requirements for labelling
and exactly what symbols to use, and
when. For example, Regulation 134.1.7
requires the provision of accurate
warning signs where there is a significant
risk of danger to the user and explains
how and where these need to be
displayed on the installation.
Warning notice,
periodic inspection
and testing labels
all have to be a
particular size
to meet current
regulations.
Tip 4: Changing rules
Make sure you’re keeping regularly up to
date with changing regulations too – they
are constantly being reviewed and updated.
For example, Amendment Number 3
came into force in January 2016, stating
that all domestic consumer units must
be made from non-combustible materials
or metal – meaning electricians have to
now make sure all labels offer excellent
adhesion to these kinds of surfaces.
Memorise this labelling checklist:

Is this durable enough to last the duration of my installation?
If handwritten, is this legible for others?
Will the weather fade or alter the condition of the label?
Do all warning labels clearly stand out?
Is this the correct size label?
Am I using the necessary symbols?
Tip 5: Requirement
vs. best practice
Remember – wiring regulations are a
minimum requirement. Best practice
labelling requires a higher standard, so
make sure you’re going above and beyond
to create an organised, safe environment
for yourself and those around you.
A professional label printer, if you’re
not already using one, can help you achieve
this. Brother UK’s flagship PT-E550W is
specifically designed to print clear, durable
labels that can be used across different
sites and components. Models come with
a variety of built in templates, including
warning and instruction labels, PAT test
labels and notices to identify RCDs and
cable wrap/flag.
The IET Wiring Regulations:
BS7671
The Institution of Engineering & Technology
(IET) is the industry authority on electrical
installation. BS7671 sets the standards for
electrical installations, both nationally and
internationally, and ensures electrical work
meets the requirements of the Electricity at
Work Regulations 1989.
Gira eNet
Easily controlling home technology via radio
Gira eNet is the new bi-directional radio system for the intelligent networking and control of modern electrical installations. Functions
such as light and blind control can be easily retrofitted and networked via radio. Installed switches can be quickly replaced or made radio-
capable without having to prise open walls and lay cables. Radio switching/dimming top units, radio wall transmitters, and radio remote
controls are available to operate the system. In addition, the Gira mobile gate also enables the entire system to be controlled using mobile
end devices running the iOS or Android operating system. This allows blinds, lights, and pre-programmed scenes to be operated
conveniently and intuitively via the Gira Interface when using WLAN at home. In the same way, the state of the lighting and blinds
can be recorded and monitored at a glance. Additional information can be found at www.gira.com/enet.
