Voltius

Voltius supports electrical conductor sizing using selected tables and criteria from the Brazilian NBR 5410 standard. It is intended for engineers, electricians and technicians working with low-voltage electrical installations.

FEATURES

• Installation methods A1, A2, B1, B2, C, D, E, F and G, with simplified selection for A and B. • Copper and aluminum conductors; PVC 70°C and EPR/XLPE 90°C insulation. • Ampacity-based conductor size preview. • Voltage-drop calculation when voltage and length are provided, with an option to recalculate conductor size. • Temperature and grouping correction factors. • Layers and parallel conductors for supported combinations, with messages when a specific engineering assessment is required. • Neutral conductor cross-section display. • Light and dark themes. • Interface available in Portuguese, English and Spanish.

REFERENCE AND SCOPE

NBR 5410:2004, corrected version 2008 — Low-voltage electrical installations.

This app does not replace consultation of the official standard or assessment of a complete installation. The current-only preview does not check voltage drop. Results must be validated by a qualified professional.

NEXT UPDATE

A calculation report is planned for the next update. This feature is not yet available in this version.
