Power Run
Planner.

This calculator is the first functional module inside the larger workspace. It demonstrates AV Stage Tools’ pattern: simple inputs, visible assumptions and a result the crew can explain.

The first gauge to pass the 3% voltage-drop target becomes the performance floor. Ampacity must be checked against the exact listed cord separately.

Planning result—not a power-up approval

Confirm the listed cord amp rating, circuit and connector, equipment manual, grounding, damage protection and wet-use requirements. Startup or nonlinear loads need qualified review.

Built for real calls

Fast answers. Visible assumptions.

AV Stage Tools keeps the simple workflow your crew asked for without pretending three inputs settle every safety question.

The quick answer

Length, load and voltage produce a useful voltage-drop floor in seconds—then the marked cord rating gets checked separately.

The reason behind it

Every result shows drop, loaded voltage, screening current and the rejected sizes that led to the answer.

The honest boundary

The interface separates a planning estimate from the cord, circuit and site checks that still require a human.

Source-backed handoff

Your sources travel with the question.

Systems Planner packages verified manuals, nameplates and production records into a bounded AI brief. Equipment claims require source IDs, while deterministic calculators keep doing the math.

Build plan

From catalog to daily workspace.

The product grows in deliberate layers. A tool only moves to live after its math, source data and user guidance can be verified.

Field notes

Know what the number means.

Short guidance sits beside the calculator, so a new crew member can make a better call without leaving the workflow.

Measure one way

Enter the distance from power source to equipment. The engine doubles it for the outgoing and return path.

Drop is not ampacity

A cable can meet a voltage-drop target and still be wrong for the circuit, connector, environment or cord type.

Use nominal voltage

Choose the actual nameplate and venue system: 120 V, 208 V or 240 V. “220” is too ambiguous for planning.
