Conductor Sizing
Four independent IEC/IS-aligned sizing tools in one place — HT cables, LV cables, busducts and earthing conductors — each checking ampacity, voltage drop, and short-circuit withstand rather than giving a rough estimate.
UPS Selection
Size a UPS system across Single, N, N+1, Distributed, 2N and 2(N+1) redundancy philosophies, with losses, battery charging load, and standard kVA rating libraries.
Generator (DG) Sizing
Size a standby diesel generator set per ISO 8528, sized on the larger of steady-state running load and the voltage-dip-limited starting requirement of the largest motor.
Breaker Sizing
Calculate full load current and recommended breaker rating for general distribution and motor feeder circuits, with instantaneous trip range for common starting methods.
