Electrical installations in residential buildings

Infrastructure of electrical installations

Electrical conduits are the infrastructure of electrical installations. Building technology is one of the construction stages of a house which is used longest - mostly for the entire life of the building. Those who want to install only the minimum equipment in the new building for cost reasons should plan ahead and include several conduits. A professional retrofit installation of cables in the wall causes dirt and is disproportionately expensive. In addition, this is hardly possible in concrete walls. Frequently, conduits show their true value years later when owners and tenants consider buying new technical gadgets

This is why a well-planned, comprehensive installation of conduits assures the builders already at the construction stage that they can always use new technologies in their home - and this with very little installation effort. Renovation and modernisation should also be used in existing buildings to install conduits to make the house ready for the future. Electrical conduits are the right investment to make residential property future-proof and are sure to pay off in the long run.

Ecological construction

FRÄNKISCHE is the first provider to launch eco-balanced electrical conduits, and pledges itself to ecological sustainability in construction. The eco-balanced co2ntrol conduits by FRÄNKISCHE reduce the consumption of fossil resources by up to 60 percent and save approx. 47 percent CO2. In order to render the co2ntrol products CO2-neutral, FRÄNKISCHE plants trees in its home region that bind and continuously store the remaining CO2 of the product group.

The two corrugated plastic conduits FBY-EL-F co2ntrol and FFKUS-EM-F 105 co2ntrol are the first eco-balanced conduits for electrical installation. The Environmental Product Declaration (EPD) issued by the Institut für Bauen und Umwelt e. V. (IBU) is based on the life cycle assessment for the entire lifespan of a product according to DIN EN ISO 14040 and 14044.

Radon prevention with the ReMo click system

You can neither see it nor smell or taste it: the inert gas radon. Once released from the soil, it enters the inside of the building through cracks and leaks in the foundation.

FRÄNKISCHE’s ReMo click electrical installation system is processed without tools and thus prevents humidity and harmful radon from entering the building through the foundation slab. The reason: The electrical installation system is mounted onto weld lines by means of an adhesive rail without using any tools, which means that the sealing layer under the screed floor does not get damaged. This prevents humidity and radon from entering the building.

Multi-media installation

The multi-media conduit conceals the tangled mess of cables around flat screens "out of sight" in the wall – simple, practical, invisible. The numerous applications of modern TVs lead to an increase in connecting cables. Surfing the internet, listening to music or watching TV to mention just a few. But where do you put the annoying cables and bulky plugs?

The oval multi-media conduit presents the ideal solution. Installed hidden under screed, the conduit collects all important cables and connects them correctly to existing devices.

Cables and plugs can be inserted and replaced even years later. This way, the owner remains flexible and can take care of technical retrofitting easily and quickly at any time.

Standards and provisions

Conduits are considered electrical equipment and are subject to the Low Voltage Directive. All electrical equipment subject to the Low Voltage Directive must bear the CE Marking. In order to comply with the safety requirements of the Low Voltage Directive, DIN VDE and DIN product standards and erection regulations must be complied with.

Erection regulations

DIN VDE 0100-520

Erection of low-voltage systems - Part 5: Selection and erection of electrical equipment; Chapter 52: Wiring systems
• Part 520 of the standards of the DIN VDE 0100 (VDE 0100) series outlines guidelines for the selection and erection of wiring systems.
• Minimum requirement on type of installation
The amendment of the standard of 01 July 2013 means:
• the end of flame-propagating conduits
• the end of pliable, resilient conduits in concrete
• a new test method for zero halogen conduits

DIN 18015-1

Electrical installations in residential buildings – Part 1: Planning principles
This standard applies to planning electrical installations in residential buildings (e.g. multi-family homes, terraced houses, single-family homes) and related outdoor electrical installations, except for equipment of technical operating rooms and operating equipment.

DIN 18015-2

Electrical installations in residential buildings – Part 2: Nature and extent of minimum equipment

DIN 18015-3

Electrical installations in residential buildings – Part 3: Wiring and disposition of electrical equipment
