A meter box ground clamp may include a body portion having a first portion, a second portion, and a gripping portion, and a fastener member configured to couple the body portion to an electrical meter box. The fastener member may be configured to extend through the first portion to engage a first surface of the meter box and move the first portion away from the first surface and move the gripping portion into engagement with a second surface of the meter box that faces away from the first surface. The receiving portion may be configured to receive the fastener member so as to create a force that urges the second portion of the body portion toward the meter box in response to a tightening torque applied to the fastener member so as to prevent the body portion from moving off the meter box in response to the tightening torque.

A plug-in connection comprises a plug-in connector (1) and a mating plug-in connector that can be plugged together with the latter. The plug-in connector (1) has a housing (2) into which an electrical conductor (3) is inserted. The electrical conductor (3) is electrically contacted with a contact partner (4) likewise arranged in the housing (2) by means of their surfaces coming to rest on each other. The contact partner (4) is contacted via its circumferential end face (5) with a contact partner of the mating plug-in connector in such a way that the end faces come to rest on each other. The plugging-together is effected and supported by a screw (6). The screw includes insulation (e.g., insulating element (12) or a coating) such that the screw (6) does not touch voltage-carrying parts such as the electrical conductor (3) and/or the contact partner (4).

A grounding system for a solar power generation facility includes a number of conductive mounting assemblies and a tension member in the form of a cable. A cable coupling of each of the conductive mounting assemblies is structured to engage and clamp the cable. The cable and each of the cable couplings has a conductivity level that is greater than a conductivity level of steel or galvanized steel, and the cable alone and respective combinations of the cable and each one of the cable couplings are each structured to provide at least a portion of a respective grounded current path of the grounding system that will be coupled to current wires and cable hangers that are supported by the cable.

In order to create a module connector for electrically conductively connecting at least two battery modules, comprising a connecting conductor, which has a contact region that is arrangeable on a contact element of a battery module, in which module connector a sufficient contact protection for a fastening element is ensured in a simple and reliable manner, it is proposed that the module connector comprises a contact protection element, which at least partially covers the contact region of the connecting conductor, and a fastening element for fixing the contact region of the connecting conductor to the contact element, wherein the fastening element in a rest position is held on the contact protection element and is transferable from the rest position into an assembly position in which a contact protection is provided for at least a protected part of the fastening element by the contact protection element.

An electrical connector assembly for a wellhead penetrator includes a first connector including an insertion body and defining a bore, the bore being configured to receive an electrical conductor. The insertion body includes a helical engaging member and defines a helical slot. The assembly includes a second connector defining a cavity therein, the cavity being configured to receive at least a portion of the insertion body therein, and the cavity being tapered such that advancing the insertion body into the cavity causes the helical engaging member to compress radially inwards into engagement with the electrical conductor.

A protective cap for an electrical connector of a wire harness has a body made of an electrically conductive material. The body has an end wall and a sleeve projecting from a first side of the end wall around a central axis. The sleeve has threads for threaded engagement with corresponding threads of the electrical connector. The sleeve and the end wall defines a receptacle. A grounding/bonding feature is integrated on an outer surface of the sleeve or the end wall. The grounding/bonding feature is electrically connectable to an electrically conductive component to electrically protect the unmated connector.
