About this tool

Calculates the appropriate wire gauge required for various direct current (DC) electrical applications based on user inputs like current draw, distance, and desired voltage. The tool allows users to input specific operational parameters, which then determines the minimum conductor size needed to safely transmit power over a given length without excessive voltage drop or overheating. It models resistive losses in DC circuits, providing precise specifications for wiring selection in low-voltage systems. Serves electricians, engineers, hobbyists, and anyone designing low-voltage DC electrical setups. Users can determine reliable wire sizing for projects ranging from solar power installations to simple battery-operated electronics.
