Wrightspark: Cable Sizing & Max Demand Trainer

Wrightspark — Cable Sizing & Max Demand Trainer

Built for electrical apprentices preparing for their capstone assessment — and for qualified tradesmen who want to keep their cable sizing and max demand skills sharp. Wrightspark turns AS/NZS 3008 and AS/NZS 3000 calculations into practice you can actually repeat, with randomly generated scenarios so no two sessions are the same.

Capstone-ready practice The capstone assessment tests exactly these skills under pressure — cable selection, maximum demand, consumer mains sizing. Wrightspark lets you drill them over and over before it counts, with instant feedback so you know straight away where you went wrong.

Stay sharp after you're qualified Not just for apprentices — if it's been a while since you last sized a cable from first principles, or you want a quick way to stay fluent in the standards between jobs, Wrightspark is built to be picked up for a five-minute session or a longer study block.

Cable Sizing Trainer Work through realistic cable selection problems — choose the right cable size for a given load, installation method, and cable type (copper or aluminium, X90 or R110 insulation), checked against AS/NZS 3008 current-carrying capacity and voltage-drop tables.

Max Demand Trainer Practice maximum demand calculations for residential and commercial scenarios, including consumer mains sizing across all three phases.
