Astronomical calculations in lighting control panel with pre-populated cities

A lighting control system for selectively connecting an electrical power source to load devices using astronomical calculations, comprising:

• a panelboard;
• a plurality of pairs of circuit breakers and switching devices modules mounted in the panelboard, each pair electrically connected between an electrical power source and a load device for selectively delivering electrical power to load devices;
• a control system mounted in the panelboard and electrically connected to the switching devices for controlling operation of the switching devices, the control system comprising a programmed controller for commanding operation of the individual switching devices in accordance with a scheduling routine stored in a memory, the scheduling routine enabling control of the switching devices based on sunrise and sunset time, the memory further comprising a database of a plurality of geographic locations and coordinate information for the plurality of geographic locations, the control system further comprising a setup routine comprising a user interface enabling a user to select one of the plurality of geographic locations and a manager routine automatically determining sunrise and sunset times using the coordinate information for the selected geographic location and providing the sunrise and sunset times to the scheduling routine.
