Cables & Wiring
KNX TP cable specifications, power cable sizing, fire-rated cables, LED strip wiring and conduit selection — written by KNX panel engineers.
KNX TP Cable — Specification and Routing Rules
The full specification for YCYM 2×2×0.8 KNX bus cable: approved colours, maximum segment length (1000m total, 700m device-to-device), star/tree/bus topology rules, and separation from power cables.
Power Cable Selection for Lighting and Power Circuits
How to size NYM-J and H07RN-F cables for lighting circuits: current capacity tables, voltage drop calculation, derating factors for bundled cables, and maximum run lengths for LED loads.
Fire-Rated Cables E30 / E60 / E90 Explained
When fire-rated cables are mandatory (escape routes, stairwells, fire alarm circuits), the difference between E30, E60 and E90 classifications, approved cable types (JE-H(St)H, FE180), and installation requirements.
LED Strip Wiring: Cable Cross-Section and Voltage Drop
Calculating voltage drop for 12V and 24V LED strips: maximum run length by cable cross-section, when to use 24V vs 12V, central vs end injection, and wiring LED strips through KNX DALI dimmers.
Conduit Types for Electrical Installations
Rigid PVC vs corrugated flexible conduit vs steel conduit vs fire-rated conduit: mechanical protection ratings, fill factor rules, KNX cable separation requirements, and EN 61386 classification.
