XLPro2 Calculation by Legrand is a professional tool for designing and verifying low‑voltage electrical installations. It enables engineers, panel builders, and installers to model networks and size equipment accurately, including cable cross‑sections with voltage drop, short‑circuit currents and thermal withstand, earthing systems (TT, TN, IT), and protective device selection. The software supports selectivity and back‑up coordination using Legrand’s catalog, helping you choose compatible protection solutions. It produces clear single‑line diagrams, bills of material, and detailed calculation reports to support compliance with IEC 60364 and relevant local codes. Automated checks, device‑setting guidance, and coordination studies speed up design while reducing errors and oversizing. From simple feeders to complex multi‑source architectures with transformers and generators, XLPro2 Calculation streamlines the path from concept to a documented, buildable, and safe installation.
