A method is described for interconnecting first, 27, and second, 22, components on a substrate, 21. The comprises attaching said first component, 27, to said substrate, attaching said second component, 22, to said substrate, 21, said first and second components being positioned relative to each other on said substrate to form a gap, 31, therebetween. The method further comprises the step of depositing a layer, 24, of electrically insulating material in said gap, and electrically connecting said first component, 27, with said second component, 22, by depositing, upon said electrically insulating layer, a layer of electrically conducting material, 26, which is in contact with and extends from a surface of said first electronic component, across said gap, 31, and said layer of electrically insulating material, 24, and to a surface of said second electronic component, 22. The method is characterised in that a plasma deposition process is used to deposit at least one of said layers of material.

A solid state switch module is provided for use in a power distribution network an input differential protection connection, 126, for receiving a measured current value from an upstream module. The solid state switch module also includes an output differential protection connection, 128, for sending a measured current value. The solid state switch module includes a trip outlet, 130, for sending a trip signal to an upstream solid state switch, and a trip inlet, 132, for receiving a trip signal from a downstream solid state switch. The trip inlet is operably coupled to the switch. A current sensor, 121, measures the current value of a connected power transmission line across the solid state switch module. A summer, 125, adds a current input from a parallel module with the current measures by the current sensor. A comparator, 123, determines includes an amount of current lost between the solid state switch module and an upstream module is acceptable.

An electrical fuse apparatus (30A) comprises a conductor element (42) defining an electrically conductive path between respective wire terminals (44, 45) for connecting the fuse apparatus to an electrical circuit. The conductor element includes a first reactive material and at least one ignition point (48) for receiving external energy to initiate an exothermic reaction of the first reactive material with a second reactive material. The reaction generates a quantity of heat sufficient to melt the conductor (42) and break the conductive path. The fuse can be an element in electrical circuits, including power controllers. A method for protecting a system using an exothermic fuse apparatus is also disclosed.
