Live Event Power Calculator

Calculate power loads, balance phases, and size breakers for your production. Stop guessing at amperage — plan your power distribution with precision.

Why Power Planning Gets Overlooked

Power distribution is one of the most critical — and most underplanned — aspects of live production. An overloaded phase trips a breaker during the headliner's set. An undersized distro melts a connector backstage. A miscalculated load draws more current than the venue's mains can handle. These aren't theoretical risks — they happen on shows every week.

Most production teams estimate power needs from memory or a rough spreadsheet. 3-phase balancing is done by feel rather than calculation. Breaker sizes are chosen based on what's available in the truck, not what the load actually requires. And when the show scales up with extra LED walls or additional amplifier racks, nobody recalculates the totals.

How Stage Tech Pro Solves This

Stage Tech Pro's Power & Mains Planner lets you add every device with its wattage, voltage, and phase assignment. Automatic load calculation per phase shows you exactly how much current you're drawing. Imbalance warnings flag uneven phase loading before it becomes a problem. Breaker sizing recommendations are based on actual draw plus safety margins. Support for both 3-phase and single-phase configurations, power factor calculations for accurate current estimation, and visual load distribution showing percentage utilization per phase.

• Device-Level Planning — Add every device with wattage, voltage, and phase assignment for precise calculations.
