Wires and cables are rated by the circuit voltage, temperature and environmental conditions (moisture, sunlight, oil, chemicals) in which they can be used. Colour codes are used to distinguish line, neutral and ground (earth) wires. Cables may be fire-resistant/flame-retardant, unarmored or armored, power or signal(control) cables, and insulated with various materials such as PVC and XLPE.
