Claim:
1. A current monitor, comprising: a. a circuit board with a current sensor comprised of one or more inductive pickup coils of wire loops, the area inside the loops situated at an angle to the plane of the board; b. at least two recesses in the board from which conductors are removably inserted; c. wherein the pickup coil is located between the recesses in the board; d. wherein, the conductors are current-carrying, e. wherein the currents in pairs of conductors are of the same magnitude but flowing in opposite directions; f. wherein the pickup coil is sensitive to a magnetic field created by the flow of current; and g. wherein the pickup coil generates a signal proportional to the currents flowing through the plane of the circuit board; h. wherein the pickup coil generates the signal continuously; and i. wherein the circuit board is a printed circuit board.
