As3000 Voltage Drop 'link' «Secure • Review»

The Wiring Rules give us a hard target. Under normal service conditions, the voltage drop between the point of supply (the mains) and any point in the installation must not exceed of the nominal voltage.

The tables usually list values assuming a conductor temperature of 75°C (or 90°C for XLPE cables). However, if your cables aren't fully loaded, they won't reach that temperature. as3000 voltage drop

Voltage drop is one of the most critical calculations in electrical design, yet it is often misunderstood or glossed over. Since you found the topic interesting, here is a write-up breaking down the nuances of Voltage Drop as per AS3000—moving beyond the basic formulas into the "interesting" practical applications and common misconceptions.
