Enter a circuit number to see its common US phase color, voltage system, panel position, neutral, ground, and field-convention note. Free lookup covers 120/240V single phase. A one-time TruePhase Pro purchase unlocks 120/240V high-leg delta, 120/208V, and 277/480V three-phase lookup, plus saved panels, project presets, custom phase colors and numbering, panel notes, load descriptions, 2-pole and 3-pole breaker labels, print-ready panel schedules, sharing, and CSV export. TruePhase is local-first and requires no account or sign-in. TruePhase is a field-convention reference, not a code-compliance guarantee or engineering design. Always verify field conditions, labeling, jurisdiction requirements, project standards, and site practice before pulling wire or energizing equipment.
