Abstract

The generation of electricity is followed by its transmission through high-voltage power lines, reaching designated receiving facilities and buildings for consumption. As specified in the Low Voltage Electrotechnical Regulations (REBT from the Spanish "Reglamento Electrotécnico de Baja Tensión"), low-voltage electrical installations (<1000V AC) in Spain must adhere to strict design criteria, encompassing conductor installation methods, spacing, type, and so forth. The developed program disclosed in this paper simplifies the calculation of phase and, if applicable, neutral conductor cross-sectional areas, ensuring compliance with REBT specific guidelines. The application delivers results within seconds, liberating users from manual calculations and regulatory searches. The main methods in low-voltage installations for cross-sectional area determination are applied: thermal heating criterion-based calculations
and voltage drop assessments. The app is available in https://www.uhu.es/dietdp/espacios_p3.php?login=1
