Claim:
1. A method for configuring a transformer for monitoring current in a power cable comprising: (a) magnetically linking said transformer with said power cable connected to an electrical device, where said transformer producing a changing transformer signal in response to the presence of a changing current within said power cable; (b) receiving said changing transformer signal by an input circuit located proximate to said transformer and having an output terminal and being electrically connected to said transformer so as to said receive said changing transformer signal, and said input circuit producing, in response to receiving said changing transformer signal, one of a first signal representative of said changing current, and a first circuit condition at said output terminal of said input circuit representative of said changing current in said power cable; (c) selectably electrically severing at least one resistor of a resistor set having a plurality of resistors having an effective resistance from the remaining said resistors of said resistor set of said input circuit, and selectably electrically severing said at least one of said resistors from said transformer when said at least one of said resistors is said selectably electrically severing from said remaining said resistors of said resistor set.
