A further reduction occurred. The line burned out the following morning about 3:30 a.m. referring now to Fig. 8, it will be noted that the current of 225 amperes was materially above the critical current for this line. This means that the losses in the cable were greater than the radiation, so that the temperature rapidly increased. A peak load of 175 amperes had previously been found possible with this line if it did not continue very long and was sharply reduced thereafter. In this case, however the load of 175 amperes, which is about the critical
load for this line, followed a peak load somewhat greater so that the temperature of the line having been materially increased by this heavy load, the total
