The color conventions for dc systems are
WebMar 10, 2024 · It's just that DC is considered (according to European norms) safe until 150V, but most DC systems are well below that. There is a reason solar panels for example should be grounded (earthed) since you tend to have higher DC voltages there than on your battery side. Ground (earth) for e.g. 48V isn't really needed for safety. http://www.isiacademy-eg.com/ElectMech/Electrical%20Eng%20Courses/ETab/Tutorial%20PDF/Chapter%2024%20-%20DC%20Short-Circuit%20Analysis.pdf
