About This Tool
The voltage drop calculator tool is used by low voltage installers to calculate AC or DC voltage drops in amps over varying cable distances. This tool uses an industry standard voltage drop calculation formula. Voltage drop is calculated by entering values the following fields in the below form and clicking on the calculate button: initial voltage, cable length, cable gauge / wires sizes and amperage (current). The industry standard for acceptable voltage drop is 10%.
This is a great tool for security installers to use in planning the best power cable sizes to use when installing CCTV cameras and other low voltage equipment. By giving installers the voltage drop percentage that can be expected, they can adjust to a gauge power cable or plan on using a power source closer to the camera they are installing.
