A heat pipe includes an insulating hollow body located inside an outer conductor. The insulating hollow body insulates a portion of the heat pipe on an outer conductor side and a portion of the heat pipe on an inner conductor side from each other. The heat pipe has a plurality of sections each connecting a corresponding one of a plurality of connection conductors to the insulating hollow body. The heat pipe further includes a communication path connecting portions of the heat pipe to each other to cause the plurality of sections to be in communication with each other. Each of the portions is connected to a corresponding one of the plurality of connection conductors.

In a method and apparatus, an electrical load is disposed across an electric power source. First and second electrical components are disposed between first and second terminals, respectively, and the load and power source. An open circuit is defined between the first and second terminals in absence of a test meter. The first electrical component is configured so that the first component passes at most a low level electric current to the first terminal upon a short circuit condition. The second electrical component is configured so that the second component passes at most a low level electric current to the second terminal upon a short circuit condition.

A generator coupling kit is provided. In exemplary embodiments, the generator coupling kit may comprise a wire adapted to couple with a generator on a first end, the wire adapted to couple with an indoor electrical panel via a generator breaker; and the generator breaker adapted to couple with indoor electrical panel, the generator breaker comprising a circuit breaker.

The circuit breaking system contains a power circuit whose voltage is greater than 600 volts, at least a circuit breaking device, at least a current detection device, a current reduction unit, at least an actuation device, and a linking device. The circuit breaking system is applicable to a high or ultra-high voltage power circuit, and the power circuit is interrupted through purely mechanical means without additional electricity provision. Even when there are major disasters that existing protection means fails, the present invention can still function and provides a trip free, ultimate self-protection mechanism so that a power system can be readily reset.
