Methods for using a pre-mount chassis to install an intelligent lighting control system

A method of using a chassis to install a lighting control system comprising:

• attaching the chassis to an electrical wall box, the chassis having at least one hook extending in an upward direction and at least one opening, the at least one hook positioned along a peripheral portion of the at least one opening;
• hanging a base module of the lighting control system from the at least one hook in the chassis, the base module including,
• a base housing forming a well and including a first electrical connector positioned in the well, the first electrical connector connected to a power circuit that is configured to receive current from an alternating current (A.C.) power supply and is configured for electrical coupling with a lighting circuit of a light fixture;
• coupling a plurality of base module wires extending from the base module to a plurality of electrical wall box wires extending from the electrical wall box contemporaneously with the base module hanging from the at least one hook, the coupled wires configured to connect the A.C. power supply to the base module;
• removing the base module from the at least one hook after connecting the plurality of base module wires to the plurality of electrical wall box wires;
• and
• nesting the base module into the electrical wall box such that the well extends through the opening in the chassis and into the electrical wall box, wherein nesting includes engaging the at least one opening in the base module with the at least one hook.
