C. Test voltage shall be 25 KV, DC. Use DC tester specifically designed for purpose, with overload or current limiting devices to limit short circuit current. Raise voltage gradually in 10 percent steps to 80 percent of final voltage, then in 5 percent steps to final test voltage, which shall be left on for 15 minutes. Take current readings at each step after current has been stabilized. Plot readings on graph paper. If breakdown is indicated during test by sudden increase in current, discontinue test, locate and remedy trouble, and repeat test. If breakdown is again indicated, replace cable.

D. Submit 2 properly labeled copies of tests to State for review. Include all necessary test information such as ambient temperature, weather conditions, current, voltage, cable length, size, etc.

3.04 IDENTIFICATION OF FEEDERS
