I am looking for the original source study that was used to develop the second level power faults in GR-1089-CORE. In other words, where did the test levels come from. Was it UL or Bellcore or possibly AT&T prior to the breakup. Specifically I am trying to find out why test 4 in Table 4-8 is limited to 2.2 amps. Why not 3, 4, 5, 6 amps for 15 minutes. I am also looking for a time-current plot or data for 26 gauge cable. Figure 4-5 in GR-1089-CORE is supposed to be similar to 32 gauge tinsel cord and mimics the Bussman fuse upper limit, however I am looking to find where 26 gauge cable would fall on this plot. Any help would be appreciated.
