Electric Wire

 is a conductive copper wire necessary for carrying electricity around the map. It is placed on the edges between cells, and carries electricity to or from a device when it is connected to the correct corner of the cell the device is in. It can only be placed on an edge adjacent to either a foreground or back wall (which includes iron supports). If the wire is placed on an edge between two foreground walls then the wire will only be visible when a wire is the currently selected item. If a wire is the currently selected item then hovering the cursor over a placed wire will show a tooltip with two numbers (or possibly ε, more below): the "+" number shows how many kW are supplied to the wire and the "-" number shows how many kW are being demanded. Having a wire as your currently selected item will also cause devices which provide or consume electricity to show a small red square in the corner where a wire must be connected.

In addition to being able to supply or demand kWs, devices can also supply or demand a current which only signals "on" without supplying any power, which is displayed in-game as "ε" (epsilon, in this context meaning "infinitesimally small power"). A device which demands ε won't consume any kWs, so a limitless number of them can be triggered by a wire which only supplies 1 kW. A device which supplies ε can't power any devices which consume kW, and can only be used to trigger devices which demand ε.

There are two ways to remove a placed wire:


 * 1) If a wire is your currently selected item, you can hover the cursor over a placed wire, causing a red "X" to be displayed.  You can then click to have the wire removed.
 * 2) If the placed wire is not adjacent to any natural back walls then removing all foreground and back walls adjacent to the wire will cause it to drop.

Note that if a placed wire is adjacent to any natural back walls, then using the miniaturizor will not remove the wire.

In-Game Description
Use it to power electric machines. Click on a cell to add it or remove it. Max power per circuit is 150kW.
