									Calculate Wire Losses

Enter Device Load in Watts                                     18     Device Watts
Enter Starting Line Voltage                                    60     Line Voltage
Enter number of pairs in Parallel                               1     Pairs
Enter Wire Run Length in Feet                                 800     Feet
Enter Wire Gauge AWG                                           18     AWG
Ohms Per Foot                                                0.006385 Calculated
Ohms Wire Run                                                    10.22 Ohms Calculated
Amps on Line                                                      0.30 A Calculated
IR (Watts lost) Lost on line in Percentage                         5.1 Keep Below 10%
IR drop should not exceed 10%
If IR drop is over 10% then increase Line Voltage, increase wire size, or reduce load
