Maya frowned. "So the pump sees low voltage, draws more current to compensate, overheats, and dies?"

Voltage drop is the reduction in voltage that occurs as electrical current flows through the resistance of a conductor (cable). Essentially, energy is lost as heat along the cable run. voltage drop calculator au

His apprentice, Maya, scrolled through her phone. "The spec sheet says the pump is 200 metres from the battery shed, Jack. We used 6mm² cable." Maya frowned

"Exactly," Jack said, wiping grease on his flannel. "Which is what the old bloke at the supply store recommended. 'She'll be right, mate.' " He sighed. "But at full tilt, that pump is trying to pull 30 amps. After 200 metres of skinny cable, the voltage isn't 24V anymore. It's more like 18V by the time it gets there."
