1. An apparatus comprising:
a first circuit configured to adjust a measurement of an alternating current, the first circuit comprising:
a switch located in a first electrical pathway between two terminals of the first circuit, wherein the first electrical pathway is configured to provide an electrical connection between the two terminals of the first circuit when the first electrical pathway is in a closed circuit configuration; and
a first electrical element located in the first electrical pathway between the two terminals of the first circuit; and
a second circuit configured to adjust the measurement of the alternating current, the second circuit comprising:
a fuse located in a second electrical pathway between two terminals of the second circuit, wherein the second electrical pathway is configured to provide an electrical connection between the two terminals of the second circuit when the second electrical pathway is in a closed circuit configuration; and
a second electrical element located in the second electrical pathway between the two terminals of the second circuit;
wherein the second electrical pathway is configured to be set to an open circuit configuration when the fuse is burned, and the fuse of the second circuit is configured to be burned based on the switch of the first circuit being in an open circuit configuration.
