Problem: The loads on your panel have been doubled (or tripled or more).
Cause: Typically, this is the result of making copies of a drawing. When a drawing is copied, copies of all of the devices are created as well. These new devices are connected to the same circuits as the original devices.
Solution: If you want to keep the extra drawing, you need to either erase the devices if you do not need them or connect them to a different circuit.
If you do not need the extra drawing, use the Delete Drawing command.
Ribbon: DM Electrical->Utilities-> 
->Delete Drawing
Pulldown Menu: DM Electrical->Utilities->Delete Drawing
This will delete the drawing and remove any devices on the drawing from the database.
