Conductor Sizing Information
Assuming an 80-foot (24 meter) loop length, each cable between the PDF and
PDP must be the equivalent of 350,000 circular mils or greater.
Calculations assume a 0.3 volt drop from the PDF to the PDP, and a 0.3 volt
drop from the PDP to the chassis. This is a total voltage drop of 0.6 volts.
Assuming an 18-foot (5.5 meter) loop length, each cable between the PDP and
the chassis must be the equivalent of 83,690 circular mils (1 AWG) or greater.
Use high-flex cable.
Calculations assume a 0.3 volt drop from the PDF to the PDP, and 0.3 volt
drop from the fuse panel to the chassis. This is a total voltage drop of 0.6 volts.
The following figure and table provide details for wiring the PFUs.
