Wire Color Code is a great app for electricians in the United States. It's a an electrical wiring color cheat sheet in your pocket. It allows you to know which color wire to pull for each circuit.
The app comes with 3 power systems and 1,000 circuits each:
• 1 phase 120V / 240V (black, red)
• 3 Phase 120V / 208V (black, red, blue)
• 3 Phase 277V / 480V (brown, orange, yellow)
The app also lets you search by circuit number. You enter the number and the app shows you the corresponding color. It's easy!
For now, the app is only following the US code but we will support more countries later on.
