Abstract: A system to determine the ground impedance of a conduit system includes a conductive sheath and a resistor of known value. The conductive sheath is configured to surround a portion of a conductor housed within a conduit system. Capacitive coupling occurs between the sheath and the conductor to establish a voltage source. The resistor is electrically coupled between the voltage source and a metal component of the conduit system, and a voltage drop is read across the resistor to determine the health of the ground impedance of the conduit system.

Abstract: A system comprises an industrial enclosure, first and second magnetic controls in close proximity to one another, and a magnetic field sensor. The first and second magnetic controls are secured to an outer surface of a cover of the industrial enclosure without penetrating an inner surface of the cover. The magnetic field sensor within the industrial enclosure senses a characteristic of the first magnetic control and a characteristic of the second magnetic control, and generates a signal corresponding to each of the characteristics. The signal is used by a controller to identify a setting of each of the first and second magnetic controls. Each of the first and second magnetic controls are positioned proximate to one another and each has a polarity and/or magnetic field strength that does not interfere with the detection of the others respective characteristic.
