It’s more that you need to show some initial effort first. The forum is not a place for requesting others to do work for you. You need to make an attempt yourself. If that means starting with some python introductions then that’s where you need to start. There are plenty of resources here on the forum, both for general python and probably for circuiting as well. Of course, you can always continue to look for custom packages that already have a working node but that can be a mixed bag.
Here are a few threads I found with just a quick search:
RIE_PowerElements for CPython3 - Revit - Dynamo
Creating an electrical circuit to electrical elements - Revit - Dynamo
Electrical Circuiting Python - Revit - Dynamo
