## What is TruePhase?

Look up the wire color and circuit phase for any panel slot in seconds. TruePhase is a fast, local-first field reference built for electricians, journeymen, and apprentices.

Type a circuit number and instantly see the common US phase color, voltage system, panel position, neutral, ground, and field-convention note. Lookup for 120/240 single-phase is free.

TruePhase Pro unlocks the 120/240 high-leg delta, 120/208, and 277/480 three-phase systems, plus saved panels with editable per-circuit load descriptions, 2-pole and 3-pole breaker labeling, auto-saved company contact info, and a printable panel schedule you can save as a PDF and post on the panel. Pro also adds project presets, custom phase colors, custom left/right starts with row step, panel notes, lookup-result copy/share, saved-panel share, and CSV export.

Designed for quick use:

- Large circuit keypad and instant phase/color result
- Common odd/even two-column panel position
