Don't worry, you can change these later on.

A disconnect provides short circuit protection, and a means of disconnecting power to safely service the application. Disconnects can be locked/tagged out in the open (off) position to ensure the system isn’t energized during service.

Use a NEMA 1 enclosure when panels are installed in clean, indoor environment. NEMA 3R is a rainproof enclosure meant for outdoor installations.

Check the motor nameplate to find your motor's rated Horsepower

Enter single or three phase based on the incoming power distribution system.

Check the voltage on your motor nameplate. This should be consistent with the supply voltage from your power distribution system.

Check the motor nameplate to find the FLA of the motor. (SFA for submersible motors)
