ArcFM data model

Can any one help me to understand what is the need of unit object class like fuse unit and switch unit in ArcFM electric data model.

Thanks in Advance

Suraj, did you ever get this figured out?

Unit objects are used to model the different components of the feature. For example, the electric network is made up of phases to denote the flow of electricity. But in GIS we will only draw one feature for the network. So a 3 phase electric line will have 3 conductor objects, or even 4 if you want to model the neutral wire. This allows to inventory the size and type of wire used. Many times the units maybe the same, but the idea of Objects allow you to keep track of all the materials used. Hope this helps...
