Cable Runs & Voltage DropEvent & Production

Select power or audio signals to calculate cable impedance, line-loss, signal degradation, and recommend the minimum safe wire gauge (AWG).

Parameters & Inputs
Precision Note

Voltage drop on power runs converts valuable electricity into heat inside the cable, risking thermal failure. Passive speaker wires demand thick conductors to prevent cable impedance from damping low-frequency bass punch.

Calculated DeliverablesInteractive Live Matrix
Voltage Drop4.0% Loss4.76V drop across lines
Round-trip Resistance0.3176 ΩTotal copper loop resistance
Wire Gauge Impedance Diagnostics
Cable Heat Power Loss71.5 Watts wasted
Safe Rated Current limit20 Amps safe peak
Feeder Health CheckAcceptable / Borderline

Voltage drop of 4.0% is acceptable but will cause warm cable runs and minor power inefficiency. Consider a thicker gauge for cooler runs.
