This article highlights key sections of Danish electrical regulations relevant to Hybird installations. It is for reference only and does not replace professional knowledge of the current Stærkstrømsbekendtgørelsen and associated standards.
RCD requirements
Danish regulations require residual current protection (30 mA) for socket outlets and certain other circuits in new installations. Hybird RCBOs provide individual 30 mA earth leakage protection per circuit, satisfying this requirement. Alternatively, a Hybird RCD can provide group protection upstream of Hybird MCBs.
Type B RCDs for DC-capable equipment
For circuits feeding equipment that may produce smooth DC fault currents — such as EV chargers, variable frequency drives (VFDs), and certain inverters — Type B residual current protection is required.
Hybird RCDs are Type B as standard. Type A is available made-to-order. Only C curve RCDs are readily available. Check current regulations and equipment manufacturer requirements for specific circuits.
Documentation requirements
Danish regulations require electrical installations to be documented. The Hybird OS Platform provides detailed records of the installed system (breaker inventory, Modbus IDs, circuit assignments, measurement history) which can supplement the required installation documentation.
Installer certification
Hybird installations must be performed by a certified electrician (autoriseret elinstallatør) as required by Danish law. Only Hybird Certified Contractors should install, commission, and service Hybird hardware.
CE certification
All Hybird breakers are CE and RoHS certified, covering both EMC (electromagnetic compatibility) and LVD (low voltage directive) requirements. Certificate copies are available on request from [email protected].
Important note
Electrical regulations are updated periodically. Always refer to the current edition of the Stærkstrømsbekendtgørelsen and relevant DS/HD and IEC standards. If you are unsure about compliance for a specific installation, consult the relevant authority or a qualified compliance specialist.
