What is the cable cross section for 150 kva?

The cable cross section for a 150 kVA load depends on several factors, including the voltage level, installation method, ambient temperature, and allowable voltage drop. Generally, for a three-phase system at 400V, a cable size of around 35 to 50 mm² is commonly used, but this can vary. It's essential to consult the relevant electrical standards and perform calculations based on specific installation conditions to ensure safety and compliance. Always consider seeking advice from a qualified electrical engineer for precise sizing.
