Systems and methods presented herein are generally directed to the location and/or identification of a circuit within a circuit. In one embodiment, a transmitter is configured for inducing a signal upon a circuit (e.g., power lines, communication lines, lighting circuits, etc.) to identify it from other circuit lines. The signal may be induced upon an individual element of the circuit through direct contact. A receiver may receive a radiated component of the signal from a distal point on the circuit to acquire the signal induced thereon and determine a strength of the signal received. Based on the received signal component, the receiver may determine location, configuration, and/or identification of the circuit from which the radiated signal is being received.
