Bs En 60228 Standard Cable [top] Today
The standard organizes conductors into distinct "Classes" based on their flexibility and construction:
The most critical pass/fail criterion in BS EN 60228 is the maximum DC resistance of the conductor at 20°C, measured in ohms per kilometre (Ω/km). This value is given for each CSA and conductor class. For example, a Class 2 copper conductor of 10 mm² has a maximum resistance of 1.83 Ω/km, while the same size in Class 5 is slightly higher (1.91 Ω/km) due to the increased length of wire from stranding. Aluminium conductors have higher resistance values (approximately 1.6 times that of copper for the same CSA), reflecting their lower conductivity. Compliance with these resistance limits ensures that voltage drop and heating (I²R losses) remain within safe and predictable bounds. bs en 60228 standard cable
