Lesson 1Cabling basics: power cables, multi-core control cables, shielded signal cables, and conduit vs tray selectionHere we learn simple things about cabling for power, control, and signals, like choosing wire sizes, insulation kinds, shielded wires, and picking between pipes or trays, watching for separation, bend limits, and noise control in South Sudan setups.
