How to get a list of SPARES and SPACES in electrical panel schedules?

Hello, I am new to using Dynamo and would like some help generating a list of all spares and spaces in all of my panel schedules.

Here is my goal: I am trying to create basic revit schedules to tabulate all breaker information in my panels. These will be exported to excel and then imported into our own internal database. Currently I have all breaker information using an electrical circuit schedule. However, I am missing all spare/spaces since Revit does not treat these as electrical circuits. I would like for dynamo to generate a list that would include the spare/space name, trip rating (if applicable), and load (if applicable). Preferably I would like it to place this information into a Revit schedule somehow.
