Author: AI Research Unit Date: April 17, 2026 Abstract Electrical installation design requires precise calculations of voltage drop, current capacity, conductor sizing, protection devices, and power factor correction. This paper presents a structured Microsoft Excel spreadsheet (XLS) as a computational tool for low-voltage electrical installations, following international standards such as IEC 60364 and NEC. The spreadsheet automates repetitive calculations, reduces human error, and serves as an educational and professional resource for engineers and technicians. The paper details the mathematical foundation, spreadsheet architecture, formulas, and practical validation. hoja de calculo excel para instalaciones electricas xls
