Detailed pages on the electrical materials — cables, protection, switchboard equipment and cable routing. Construction, use and what you need to know to choose the right one for the job.
Cables
Fixed installation for lighting and light circuits
3 conductors (L, N, PE), 1,5 mm². Lighting circuits and light-duty circuits in dwellings. The current-carrying capacity depends on the installation method — refer to DS/HD 60364-5-52.
Ordinary socket-outlet circuits
3 conductors (L, N, PE), 2,5 mm². Standard socket-outlet circuits in dwellings. Verify the current-carrying capacity according to the installation method.
Fixed installation for 3-phase circuits
5 conductors (L1, L2, L3, N, PE), 2.5 mm². 3-phase circuits, e.g. power outlets and smaller machines. The current-carrying capacity depends on the installation method — look it up in DS/HD 60364-5-52.
Flexible supply cable for appliances
3 conductors (L, N, PE), flexible stranded. Supply leads for appliances and equipment that get moved around. Choose the cross-section according to load and length.
Udendørs og nedgravning — UV-bestandig PVC-kappe
3 ledere (L, N, PE), 2,5 mm², sort PVC-yderkappe (NYY-J). Udendørs fast installation, nedgravning og fugtige omgivelser. Belastningsevnen afhænger af installationsmetode og jordtemperatur — slå op i DS/HD 60364-5-52. Vejledende pris: ~12–16 kr./m (PriceRunner juni 2026).
Brandklassificerede bygninger og flugtveje
3 ledere (L, N, PE), 1,5 mm², halogenfri (NHXMH). Kræves i brandklassificerede bygninger og flugtveje (EN 13501-1). Frigiver ikke korrosive gasser ved brand. Belastningsevne verificeres mod DS/HD 60364-5-52 tabel; tværsnit og installationsmetode er afgørende.
Protection
Residual current device against electric shock
Rated residual current 30 mA, typically type A in dwellings. Protection against electric shock in accordance with the applicable regulation. Choose the type according to the nature of the load.
Branch circuit breaker for overcurrent protection
Rated current 16 A, characteristic C. Overcurrent protection of circuits. The characteristic (B/C/D) is chosen according to the load type.
B characteristic for lighting and ordinary circuits
Rated current 13 A, characteristic B. Lighting and ordinary domestic circuits. B characteristic for loads without large inrush surges.
Fault and overcurrent protection in a single module
Combined RCD + miniature circuit breaker, typically 30 mA. Individual earth-fault and overcurrent protection per circuit. Rated current, characteristic and type are chosen according to the load.
Fejlstrømsafbryder til ladestandere uden DC-blokering
Type B RCD registrerer sinusformet, pulserende og glat jævnfejlsstrøm op til 1000 Hz. Kræves ved ladestandere, der ikke har godkendt DC-fejlstrømsblokering (RDC-DD ≤ 6 mA DC) — jf. DS/HD 60364-7-722. Vejledende pris: ~1.500–3.000 kr./stk. (vat.dk, vejledende juni 2026). Kilde: elsikkerhed.dk/ladestandere-i-boliger.
Switchboard equipment
Enclosures for switches and documentation
Flush-mounted or surface-mounted enclosure. Junction point for circuit breakers and protective equipment in residential/commercial premises. Enclosure rating and number of modules are chosen according to the environment and requirements.
Busbar linking the terminals of several breakers
1-, 3- and 4-pole versions. Efficient interconnection of breaker rows in the distribution board. Rated current and number of poles are chosen according to the configuration — see supplier data.
Cable routing paths
Flexible conduit for concealed routing
Nominal size M20, flexible conduit. Concealed routing and replaceability of cables. The conduit size is chosen according to the number and cross-section of conductors.
Box for junctions and branches
Terminal connections; the enclosure rating (IP) is chosen according to location. Accessible junctions outside the distribution board. The enclosure rating is chosen according to the surroundings — see supplier data.
Synlig kabelføring i lokaler
PVC-kabelkanal, 40×25 mm, hvid (standardfarve). Synlig og tilgængelig kabelføring i kontorer, butikker og erhvervslokaler. Bredde og højde vælges efter antal og dimension på kabler. Husk kapslingsklasse (IP) ved fugtige rum — se leverandørdata.
