Color Codes
5. A Spectrum of Standards
While we've touched on color codes, let's delve a bit deeper. As we've said, these aren't foolproof! Color codes for L and N wires can vary depending on your region, the age of the wiring, and even the specific application. Consider them a helpful guide, but always verify with a voltage tester.
In North America, the "L" wire is typically black, and the "N" wire is white. The ground wire is usually green or bare copper. In Europe, the "L" wire is often brown, the "N" wire is blue, and the ground wire is green and yellow striped. However, older installations may use different colors, or even have no color-coding at all.
That's why it's essential to never assume based on color alone. Use a voltage tester to confirm the identity of each wire before working with it. A voltage tester is a simple and inexpensive tool that can save you from a potentially dangerous situation. It's a worthwhile investment for anyone who works with electrical wiring.
Think of color codes as a starting point, but not the final answer. They can provide a clue, but you need to confirm that clue with solid evidence. Always double-check, verify, and prioritize safety above all else. Remember, electricity doesn't care what color the wire is; it will still bite if you're not careful.
