## What is AmpCore?

AmpCore is a professional electrical calculator built for electricians working with European standards. While most apps focus on US codes, AmpCore uses IEC 60364 calculation methods with metric units by default.

FREE CALCULATORS

- Voltage drop — with conductor temperature and material (Cu/Al)
- Circuit breaker selection — standard EN ratings, curve guidance (B/C/D)
- kW to Amps converter — with EU voltage presets (230/400 V)

PRO CALCULATORS
- Cable sizing — installation method, temperature and grouping factors, with the full calculation shown step by step
- Motor current — with typical efficiency and power factor presets
- Conduit fill — with recommended fill limits
- PE conductor sizing — adiabatic method and simplified method

BUILT FOR THE JOB SITE
- Works fully offline — basement, site, or shed
- Instant results as you type, no "calculate" button
- Large touch targets, usable with gloves
- Every result shows which standard and table it is based on
