Description
HAK Cable Size Estimator helps engineers right‑size power cables quickly and confidently.
Highlights
Ampacity‑based selection with ambient, grouping, and installation reduction factors (offline tables).
Voltage drop using R‑only or R+X, with temperature correction, frequency input, and power factor.
Systems & materials: single‑ or three‑phase; copper or aluminum; built‑in AWG/MCM data.
Parallel runs: evaluate single run or search for multi‑run solutions when needed.
Motor helper: choose kW & IE class to auto‑estimate current (with optional 1.25× FLA).
Fast, offline calculations; 8 languages supported.
How it works
Enter load (or use Motor helper).
Set environment: temperature, grouping, installation.
(Optional) Enable R+X and voltage‑drop constraint.
Get the smallest cable that meets your constraints—single or parallel runs—plus a concise math trace.
Free vs Premium
Free: Ampacity sizing, reduction factors, manual parallel runs, presets, motor helper.
Premium (HAK Pro): Voltage‑drop constraint check (R or R+X), automatic parallel‑run search, frequency input for R+X.
