C 11.1 Conductor Cross-section
The conductor cross-section selected for defined current flow, without
exceeding given voltage drop. When connecting flexible conductors, note the following:
for screw terminals without wire protection, highly recommend the use
of wire ferrules cable lugs.2 Mechanical Criteria
