A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...
Some vehicles may have more power outlets: usually one for the front passengers, one for the rear passengers and one for the luggage trunk. The voltage of the power outlet is usually near 12 V DC, and may be elevated between 13.5 V to 15 V while the engine is running. On trucks, the voltage of the power outlet may be near 24 V DC.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
These fast over-voltage transients are present on all distribution networks and can be caused by either internal or external events, such as lightning or motor arcing. Transient voltage suppressors will fail if they are subjected to voltages or conditions beyond those that the particular product was designed to accommodate.

Arcing horns protecting bushings on a distribution transformer. Arcing horns form a spark gap across the insulator with a lower breakdown voltage than the air path along the insulator surface, so an overvoltage will cause the air to break down and the arc to form between the arcing horns, diverting it away from the surface of the insulator.

A lightning rod is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. Lightning Rods may refer to: Lightning Rod (roller coaster), a roller coaster located at Dollywood theme park in Pigeon Forge, Tennessee; The Lightning Rods, an alternative name for the comics characters Great Lakes Avengers
