# Aircraft Electrical Events<no value>
The event IDs listed here are all related to the aircraft electrical systems.

Please note that many of these events are flagged as using an electrical component name (or index). Using the name is **only applicable to the v2.00+ electrical system**, and is the recommended way to target a specific component. If you are using prior versions, only the index is valid and names will not be accepted. If you are supplying a name for the component, it should be supplied in single quotes `''` followed by `_n`. For example, consider this [line.N](../../../content-configuration/cfg-files/system/modular-electrical-system-information/#linen) definition:

``` cpp
line.1 = Name:115V_AC_XFR_BUS_1_To_EXT_GEN_BUS # Connection:ConA(115V_AC_XFR_BUS_1,EXT_GEN_BUS)
```

When using this line via [RPN](../../reverse-polish-notation/) in your model behaviours, you would have something like this:

``` xml
'115V_AC_XFR_BUS_1_To_EXT_GEN_BUS'_n (&gt;K:ELECTRICAL_LINE_CONNECTION_TOGGLE)
```

instead of:

``` xml
1 (&gt;K:ELECTRICAL_LINE_CONNECTION_TOGGLE)
```

### APU 

The following events are only viable for aircraft with at least one [`CIRCUIT_APU_STARTER`](../../../content-configuration/cfg-files/system/electric-system-setup-information/#CIRCUIT_APU_STARTER) circuit defined.

{{< callout context="note" title="NOTE" icon="outline/bulb" >}}

While it appears that you can define multiple APUs in an aircraft, currently the simulation <strong>will only permit <em>one</em> APU to work.</strong> This may change in future updates.
