Prepare the Electrical Design

Create the distribution systems and define the components that you want to have available for your design.

Specify distribution systems.   Define distribution systems that specify voltages, and conductors for the systems in the project.
Specify wiring.   Define wire sizes and wire types to be used in the project.
Select the equipment, devices, and lighting fixtures for the systems.   Load the devices, fixtures, and equipment that will comprise your electrical systems.

You are now ready to design the electrical system.
