How to Calculate Maximum Demand for a Three-Phase Industrial Unit (AS/NZS 3000 Appendix C)

Determining the electrical maximum demand for a proposed factory unit can be challenging — especially when the building doesn’t yet exist. In this video, we walk through a complete worked example from Appendix C of AS/NZS 3000, specifically following the method shown in Example C2.4.2.2, to estimate the maximum demand of a three-phase industrial installation. You’ll learn how to identify and allocate loads into the correct load groups, including specialised items such as welding machines and three-phase motors. We’ll cover: • Using Table C2, column 3 for factory units • Allocating standard and specialised loads (lighting, socket outlets, air conditioning, HWS, motors, welders) • Applying duty cycles and primary current rules for arc and resistance welders • Balancing loads across phases to determine which phase carries the highest current By the end of the walkthrough, we calculate the total phase currents and identify the maximum demand for the installation. You can even try adjusting some of the single-phase loads yourself to better balance the phases. ----- Become an ELECTRICAL APPRENTICE with us: https://bit.ly/37m3cCx Are you LOOKING FOR A CAREER?
