Disclosed are implementations of a cable management device. An example cable management device can be attached to the handguard of a firearm, and used to route an electrical cable (or wire) connecting a remote switch to a firearm accessory, such as a flashlight. An example cable management device comprises: a body portion that includes a cable guide channel configured to receive therein a portion of an electrical cable; an elongated threaded fastener that includes a countersunk head; and a pivot fastener. The body portion is configured so that the countersunk head of the elongated threaded fastener can capture the portion of the electrical cable positioned within the cable guide channel. In some implementations, the body portion includes two cable guide channels, each of which is configured to receive therein a portion of an electrical cable.

A device and method of positioning a component on a cable. The method includes: moving a collet into position on the component; engaging the component with the collet; moving the collet with the component positioned thereon into alignment with an end of the cable; securing the collet to the end of the cable; moving the component from the collet to the cable; and removing the collet from the end of the cable.

The application relates to a transmission cable joint for a medium voltage underground cable system. The cable joint comprises at least a casing and connection terminals for coupling wires of transmission cables. In addition, the connection terminals are in connection with an inductance component that is sheltered by the casing and limits capacitive earth fault current, when the coupled cables produce such current.
