AT&T LTE POWER CABLE VOLTAGE DROP TABLES

1) Load current assumed at 37.5A representing highest possible value (1500 watt RRU at lowest voltage)
2) Values based on 30 degree Celsius
3) Nominal Battery Terminal Voltage of 48 VDC
4) 40 VDC minimum voltage at the RRU power terminals (8 volt drop over trunk/jumper combination)
5) Any voltage drop reading appearing in RED requires the next size cable, jumpers or PowerShift
6) Assumes power cable is TC-ER Labeled, 90C
