Lug assemblies include a housing with at least one internal printed circuit board with electronics and lugs. The lugs attach to cables providing power/current. The printed circuit board includes at least one electrical ground connector and at least one electrical contact connector. The lug assemblies include terminals that indirectly electrically couple the cables to terminals of switching devices such as circuit breakers.

A terminal protection voltage detector circuit is provided for protecting a terminal block having output terminals in a power supply apparatus. A current detector detects output currents flowing from the power supply apparatus to loads via output terminals, and a first comparator configured to compare a sum of the detected output currents with a predetermined first threshold and output a first comparison result signal when the sum of output currents is larger than or equal to the first threshold. A second comparator configured to compare a maximum value of detected output currents with a predetermined second threshold and output a second comparison result signal when the maximum value is equal to or larger than the second threshold. A current stop circuit stops a current from flowing from the power supply apparatus to the output terminals based on the first or second comparison result signal.

The invention relates to a device combination for protecting electrical networks against overvoltages or overcurrents, comprising an essentially U-shaped base and at least one plug-in module, which can be plugged or pushed onto the base, wherein the base has connection terminals for connecting to the respective network and also has plug-in contacts, which are connected to the connection terminals and are complementary to mating plug-in contacts or contact tongues of the plug-in module, and the plug-in module has a housing which accommodates one or more lightning and/or overvoltage arresters, and the mating plug-in contacts or contact tongues pass through a floor side of the housing. According to the invention, means are provided for changing the position and the distance between the plug-in contacts and the mating plug-in contacts or contact tongues, wherein, starting from a working position, with a closed, surge-current-resistant electrical connection, it is possible to select an idle position, in which the plug-in contacts and mating plug-in contacts or contact tongues are located in an isolation/disengagement position.

This disclosure includes a system and method for integrating a power system having one or more electrical receptacles, a charging system having one or more USB charging ports, and a lighting system into one component for ease of installation and use in any environment including, for example, under cabinets, above and below countertops, at workstations, desks, overhangs, or other areas. The wiring may be split at the entrance into the chassis. Continuous power may be maintained at the receptacle locations while also powering the LED lighting via a control device such as, for example, a slide dimmer, an in-line dimmer, a wall-mounted dimmer control device, a remote control, or a WiFi connectivity device. The use of an in-line GFCI device may also be incorporated into the complete system.

A method for assembling a module configured to limit power surge exposure to an electrical device may include providing a carrier configured to receive at least one electrical conductor and at least one surge protection component. A lug defining a hollow space is provided in a pocket of the carrier, and an electrical lead of a surge protection component and an electrical conductor are provided in the hollow space of the lug. The method includes crimping the lug onto the electrical lead of the surge protection component and the electrical conductor such that the electrical lead and the electrical conductor are physically and electrically coupled to one another. The carrier may include multiple pockets receiving multiple lugs, and the multiple lugs may be crimped substantially simultaneously to physically and electrically couple corresponding pairs of electrical leads and conductors.

The present disclosure relates to a three-phase terminal block having a leakage current limiting function, in which a leakage current may be limited by expanding an area of a neutral line of a three-phase four-wire line connected to the terminal block, and thus the risk of electric shock to the human body due to the leakage current may be minimized.
