Performance of distribution board at elevated temperature is vital in the context of reliable operation of electrical network. Guidelines and specifications are available in IEC for distribution board at ambient temperature. This temperature range covers from 23 degrees C to 40 degrees C. The performance at elevated temperature of distribution board is not well known and hence the studies are conducted by subjecting the distributing board to 2500A rating to temperature rise test at elevated temperature of 55 degrees C. The temperatures and the rise values are monitored till thermal equilibrium of distribution board is obtained. The results obtained are analyzed in conjunction with international standards. The studies revealed that thermal performance of distribution board exhibited higher temperature rise values. These studies, results, experimental arrangements are presented in the present research work.
