Abstract: An electrical coupler for coupling a load to a plurality of power sources including positive and negative load connection points. These connection points include first and second positive power connection points and first and second negative power connection points. A first electrical path is provided between the positive load connection point and the first positive power connection point. A second electrical path is provided between the positive load connection point and the second positive power connection point. The second electrical path is the same length as the first electrical path. A third electrical path is provided between the negative load connection point and the first negative power connection point. A fourth electrical path is provided between the negative load connection point and the second negative power connection point. The fourth electrical path is the same length as the third electrical path.
