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.
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.
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
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.
Electrical installations in residential buildings – Part 2: Nature and extent of minimum equipment
Electrical installations in residential buildings – Part 3: Wiring and disposition of electrical equipment

DIN EN 61386-1 (VDE 0605-1)
Conduit systems for cable management – Part 1: General requirements
• This standard defines requirements and tests relating to conduit systems, including conduits, conduit fittings and accessories, for the protection and routing of insulated wires and cables in electrical installations or in communication systems up to 1,000 V a.c. and/or 1,500 V d.c.
• Conduit classification codes

Outside diameters of conduits for electrical installations and threads for conduits and fittings
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.

Wall or ceiling breakthroughs are called firewalls or fire stops. They must be sealed off such that fire cannot propagate into adjacent fire sections. Fire stops must feature the same fire resistance as the respective wall or ceiling. The term circuit integrity is closely connected with the term fire resistance and means that a component functions in normal use over a long period of time before it is subjected to fire. The conduit installations have been tested and approved for E30, E60 and E90 with various cable manufacturers.

Low Smoke - zero halogen
The main danger to humans and buildings in case of fire are not the flames but the development of smoke gas.
Zero halogen low smoke conduits reduce corrosive and toxic gases to a minimum. All FRÄNKISCHE zero halogen conduits are tested zero halogen according to DIN EN 50642.
