Residential buildings Conserving living comfort
Example without external lightning protection Surge protection solutions
Nowadays, smart technology forms the basis for modern living. It offers comfort,
security and independence. Surge protection is instrumental in ensuring that this
technology is reliable.
Safeguarding living comfort in smart homes
L
Modern lifestyle is increasingly defined by digital devices: Smart TV, intelligent home
automation, burglary protection systems, home office or electromobility to name
but a few. A lot of us already take the comfort of smart homes for granted. The
downside of smart is that devices are becoming increasingly sensitive and more
F E susceptible to interference. Surges can cause serious interference and damage or
even destroy important networked technology. This may cause the entire smart
G system to collapse leading to a drop in the accustomed standard of living.

Observing surge protection requirements
A B Vital technology is becoming more and more sensitive but, at the same time, requires
C D I higher protection. For this reason, the IEC 60634-4-44 clause 443 and IEC 60364-5-53
clause 534 standards were revised and adapted accordingly. IEC 60634-4-44 clause
J 443 describes when surge protection measures need be taken in systems and build-
ings - IEC 60364-5-53 clause 534 explains how to select arresters and install them
in the electrical installation. Upon the issue of the new edition of IEC 60364-4-44
clause 443, surge protection became mandatory for new residential buildings.
Surge protection To ensure comprehensive protection, dangerous surges must be prevented from
entering the building. Therefore, measures must be taken for incoming lines such as:
A Main distribution board / B Internet / telephone C Broadband / Satellite D Photovoltaics Power supply lines
service entrance box
Internet and telephone lines
Broadband cables
Lines extending beyond the building

Surge protection is important to ensure that all the devices in modern homes work reliably since there is more at stake than
