Nets
Initially, CCX combines all adjacent conductive parts to a common net and creates an entry in the electric net list for each net. These nets can further be combined manually. In the following example, the two highlighted nets are actually one as they are connected by the interior elements of the fuse. The interior elements are, however, not in the model. Therefore, you need to manually merge the nets.
1. Select Net 2. The pin, the fuse, and the live wire terminal are all one net. This is because the application understands that the fuse is connecting the two parts.
 
To manually merge nets, use Merge Nets.
Auto Merge Nets allows you to automatically merge all the nets which are close together to account for small gaps in the assembly. To automatically merge all the nets, specify the value of maximum gap size in Auto merge distance field. Then, click Auto Merge Nets to combine all the nets which fall below the specified distance.
2. Rename Net 2 to Live, Net 3 to Body Screw, Net 4 to Grip Screw, Net 5 to Neutral, Net 6 to Earth.
 
* The following net types are available:
Potential— The net is supplied with an electric potential. Such a net can act as source as well as target of a creepage or clearance path.
Grounded
— The net is explicitly grounded and can act as target of an analysis.
Potential-free
— The net is neither supplied with an electric potential nor is it grounded, for example, screws. Such a net can act as intermediate source and can foreshorten a path.
* Nets of the type Potential or Grounded are referred to as entity nets. For an analysis, specify at least two entity nets.
3. Set the Net Type for Earth as Grounded.
4. Set the Net Type for Live and Neutral as Potential.
5. The unit of Auto merge distance is mm or inch. To change the unit of Auto merge distance from inch to mm, click Menu > Options.The Options dialog box opens.
6. Change the Unit from inch to mm.
7. Click OK. The unit of Auto merge distance is now mm.
