LV cable sizing
Full BS7671:2018+A2 sizing with correction factors Ca, Cg, Ci, Cc and methods A–G.
LV cable sizing, voltage drop, fault current and adiabatic checks — wired directly to BS7671 Appendix 4. Professional PDFs, calculation history, AI assistance.
Six calculators built around the same compliance engine — switch freely without re-entering the project context.
Full BS7671:2018+A2 sizing with correction factors Ca, Cg, Ci, Cc and methods A–G.
Instant check against Section 525 limits — 3% lighting, 5% other circuits, mV/A/m tables.
IPSSC calculation and adiabatic withstand check S = (I·√t)/k per BS7671.
Export cable schedules and full calculation sheets ready for project documentation.
All your sizings in one place — searchable, taggable, re-openable, exportable.
Derive design current from motor kW, efficiency and power factor automatically.
No black boxes. Every coefficient, every table lookup, every intermediate result is exposed in the workspace. The same workflow you'd use on paper, just faster.
