PowerSense
Turn a rig list into a phase plan — loads balanced across L1–L3, cable runs compared with guideline values, and a printout the venue electrician can check.
On this page
PowerSense helps you arrive at load-in with a power plan instead of a guess. Enter the gear in watts, VA or plated amps; it converts at mains voltage, applies your power factor and safety margin, balances everything across the three phases and tells you where each device landed. Then it compares every cable run with guideline values and prints a draft for the electrician.
Who it is for
- Touring and freelance techs advancing the power requirement before the truck rolls.
- Lighting crews with dimmed conventionals, LED PSUs and motor controllers on 400 V.
- Festival and outdoor crews on generators, where the 70 % rule is not optional.
What makes it different
- A phase plan, not a total. Auto-balance places devices largest-first on the lightest phase, splits a row of several units across the phases and shows on the row where they landed. Pin the plan and it becomes the plug-in sheet.
- Loads and cables in one tool. Every run has the breaker that protects it, its own 1-phase or 3-phase setting and derating for a drum, bundling or a hot day. See Check cable runs.
- It says what it does not know. Lists that are mostly LED or switch-mode get a neutral-current warning, and the printout lists what the plan does not check.
- One list per distro. FOH, stage left, lighting, catering — with a site overview that adds them up in W and kVA.
- Four regions. Europe, UK, North America and Japan; decimal commas work.
- Honest guidance. The eight good-practice rules are built in and published at /powersense/good-practice.

PowerSense is free with a Squaresmile account and works on a phone.
PowerSense is a planning aid. It compares your list with guideline values for flexible rubber cable; it does not check an installation. Earthing, loop impedance and disconnection time, RCDs, how the cables are laid and every measurement are the electrician's job. The real installation is designed, built and inspected by a qualified electrician — always.
Thanks for the feedback.
