Description
IEC Box & Conduit Calc simplifies electrical planning using IEC 60364 principles.
Designed for electricians, contractors, and engineers, the app provides practical, on-site guidance for conduit occupancy, box capacity, and cable pulling complexity—helping you make confident installation decisions without guesswork.
Key Features
• Conduit Fill Method
Calculate conduit occupancy from conductor geometry and internal conduit area, with clear IEC-style space guidance to reduce overcrowding and support safe heat dissipation.
• Box Capacity
Evaluate usable volume for junction and device boxes using representative IEC box dimensions. Instantly view occupied volume, free space, and fill percentage.
• Run Complexity
Assess cable pulling difficulty before installation by tracking cumulative bend angles and pathway limits. Identify when pull boxes or route changes are required.
• Point Factor Method
Apply commonly used pulling and installation factor concepts to compare routing scenarios and account for installation difficulty—not just physical space.
Designed for the Job Site
• Works fully offline
• Clean, distraction-free interface
• Dark Mode support for low-light environments
• Fast and reliable calculations
This app provides installation guidance only. IEC 60364 does not define fixed conduit or box fill limits. Always verify designs against local regulations and manufacturer specifications.
