"Not yet!" he shouted back, spitting out the flashlight.
He grinned. "We're not wiring a lamp, Elena. We're feeding a dragon. And this little calculator just told me exactly what gauge sword to use."
This paper presents a standardized methodology for calculating the required thickness (cross-sectional area) of electrical cables in low-voltage power distribution systems. The selection of appropriate conductor size is critical for ensuring system safety, operational efficiency, and regulatory compliance. This document analyzes the three primary constraints governing cable sizing: current-carrying capacity (ampacity), voltage drop limitations, and short-circuit thermal stability. A calculation algorithm is proposed, and the influence of installation methods and ambient conditions is discussed.

Elena looked at him. "Well?"
Electrical conductors possess impedance. As current flows, a voltage drop occurs, potentially delivering insufficient voltage to the load. Standard practice typically limits voltage drop to 3% for lighting and 5% for power circuits.
Several factors influence the selection of cable thickness, including:
The formula for voltage drop ($\Delta V$) is:
