$0.29 · Designed for iPad. Not verified for macOS.

An offline utility for electricians, low-voltage installers, equipment technicians, and home distribution planning. It helps estimate cable voltage drop from voltage, power, current, distance, and conductor material, then provides reference wire size suggestions and saves common projects for quick field review. Key features: 1. Cable voltage drop calculation: supports single-phase and three-phase circuits, with voltage drop value and percentage based on voltage, current, length, and material. 2. Wire size suggestions: recommends common copper and aluminum cable sizes based on load power, distance, and allowed voltage drop. 3. Power and current conversion: quickly convert between W, kW, A, and V for on-site estimates. 4. Ampacity reference: built-in reference tables for common cable sizes, copper and aluminum conductors, and installation notes. 5. Project saving: store common line plans locally with notes, copied results, and history review. This app is a standalone offline utility. It does not require sign-up or login, does not connect to any server, and does not collect or upload user data. All calculation records and project data are stored locally on the user's device only.
