Assumptions
1.0 mm (18 AWG) stranded copper 457 m (1,500 ft) twisted
wire
0.8 mm (20 AWG) stranded copper 297 m (975 ft) twisted
wire
0.6 mm (22 AWG) stranded copper 183 m (600 ft) twisted
wire
A
0.5 mm (24 AWG) stranded copper 107 m (350 ft) twisted
wire
100 mV maximum
voltage drop
Depending on the
cable length and the
connected input or
output device, you
may have to define
an offset in the setup
software for the input
or output point.
