Toptronic Assistant, an Electrician’s Field Toolbox

Why it surfaced

Toptronic Assistant is unusually specific about the work it supports, including ampacity correction, the 125% continuous-load rule, motor FLA, and country-specific standards such as NEC, IEC 60364, BS 7671, and AS/NZS 3000. The homepage is spare—a single Download link and a Features section—but the breadth of the promised field reference makes it a useful arrival for electrical designers.

A desktop calculator suite for electricians covering wire and breaker sizing, voltage drop, motors, lighting, energy costs, transformers, and wiring-colour references.
