Do connecting conduits to appliances have to meet the fire class requirements set in CPR or Environment Buildings Decree (BBL)?

Answer:

  • According to NEN1010, short connection cables for devices may deviate from the minimum requirements as long as they are short and do not extend to other fire compartments:
  • NEN1010:2020 527.1.4: If cables that do not meet the minimum requirements for resistance to fire propagation as per NEN-EN-IEC 60332-1-2 are nevertheless used, they must be limited to short lengths for connecting devices to fixed cabling systems and may under no circumstances be allowed to pass into other fire compartments.
  • This is a safety requirement, so it is wise to define ‘short’ as being as short as possible, e.g. 50cm. This also prevents the cable from unexpectedly being pulled through to another fire compartment.
  • According to the BBL, Art. 4:46, depending on the type of application, a small percentage (often 5% at most) of the surface of a construction component (such as a cable) in a space may be exempted from the required classification.
  • If a device, such as a lighting fixture, is certified including the connecting cable, then it falls under the Low Voltage Directive rather than the CPR or BBL, and the requirements of the BBL do not apply (of course, the requirements of the Low Voltage Directive do apply).
  • However, in many cases, you may have discussions with customers or inspection authorities about this: What is short length? Is a power socket also a device? (no), Is a connecting cable that has been attached to a device by a fitter, not by the manufacturer, covered by the manufacturer’s CE declaration? (no) When is a pluggable electrical cable a connecting cable and when is it not? In most cases, it is therefore easier to use a connecting cable with Euro class B2ca or to equip a device with a chassis socket and feed it with a coupling cable that meets the Euro class of the installation.
