Preferred class and definition ambiguity between Disconnect_Switch and Isolation_Switch.

[metesaka]

Currently Isolation_Switch is the preferred class and Disconnect_Switch is an alias. During the cleanup #704, alias class definitions are removed. However, now the result is that Disconnect_Switch has no definition, and Isolation_Switch has a definition of "See 'Disconnect_Switch'".

(see chat #706)

We should decide which of these should be preferred class and move the definition to either of them.

I would prefer Disconnect_Switch to be preferred. It has subclasses that utilize this name too. It is also a name I believe is more common.

according to some articles I was reading today, these seem like different pieces of equipment. My proposal is to remove the alias and have them be distinct classes

Just to make this more complicated...
Currently, Main_Disconnect_Switch has the following very verbose definition:

Building power is most commonly provided by utility company through a master disconnect switch (sometimes called a service disconnect) in the main electrical room of a building. The Utility Company provided master disconnect switch often owns or restricts access to this switch. There can also be other cases where a disconnect is placed into an electrical system to allow service cut-off to a portion of the building.

I was confused about the distinction between Main and Building disconnect (which has no definition). Searching some, it seems like these are often used interchangibly. I wonder if Building_Disconnect_Switch is needed or these should be considered equivalent. If they are not equivalent, then Building_Disconnect_Switch needs a definition explaining it.

Given that Building Disconnect Switch doesn't have a definition, I'm inclined to deprecate that class and stick with Main Disconnect Switch as the primary class to keep. We can then associate the main disconnect switch with a building if we want
