Parallel single-core (single-conductor) cables are employed in the backbone of building distribution systems. As power consumption in buildings grows continuously, overheating problems associated with such a cable installation have become a concern. This paper investigates the current distribution among parallel single-core cables installed on metal tray in a multi-phase distribution system. A general prediction method of current distribution is introduced, and is validated experimentally. To analyze current distribution under different cable arrangements, empirical formulas of cable impedance are presented. The current distribution associated with the local practice of parallel cable installations is evaluated and recommendations for the design and installation are presented.
