is an equivalent wire calculator designed for electrical machine maintenance services like motor and transformer rewinding. Often, you are required to find thinner wire combinations instead of the original wires for easier rewinding. Or, you may not have the required wires for a given coil in your inventory, and need to use what you currently possess. In such cases, wires can be used in parallel.
EqSWG can help you calculate combinations of cross-sectional areas of your original wire with the cross-sectional areas of other wires.
It can provide you with cross-sectional area combinations in the +/-0.5% tolerance range.
