Voltage Drop and Wire Gauge Calculator

Free tool, no sign-up. Enter the voltage, current, conductor gauge and run length, and see how much voltage actually reaches the device — plus the maximum run length for a 5% drop and the minimum gauge for the target you set. It works for 12V and 24V CCTV runs, gate operators, access control and LED feeds, in AWG or mm².
