The international color code for three-phase electrical systems typically uses the following colors: Brown for Phase 1 (L1), Black for Phase 2 (L2), and Gray for Phase 3 (L3). This color coding helps ensure safety and consistency in wiring across different countries. Additionally, the neutral wire is often blue, and the earth/ground wire is green/yellow. Always refer to local regulations, as codes may vary by region.

What color should the wires be in a 120v system?
It depends. In a typical US residence with 120/240v single-phase power, the ground wire will be green, the neutral will be white, and the hot conductor will be either black or red depending on which phase it is connected to. Odd numbered breakers (1,3,5, etc.) are black, and even numbered breakers are red. You will measure 120v from black to white, also 120v from red to white, but 240v from black to red. In a commercial building with 3-phase 120/208 power, ground and neutral are the same color, but there are 3 hot colors - black (a-phase) red (b-phase) and blue (c-phase). As you run down a line of breakers from top to bottom they will be wired: black red blue black red blue etc. You will measure 120v from any of the 3 hot colors to white (neutral) but 208v from black to red, red to blue and blue to black.
