Illustrative embodiments of systems and methods for powering lighted shelves in refrigerator appliances are described. In one embodiment, a refrigerator appliance may comprise a cabinet having a temperature-controlled compartment defined therein, a shelf ladder disposed at least partially in the temperature-controlled compartment and providing a plurality of shelf mounting positions, the shelf ladder comprising an electrical bus including first, second, and third conductors, the second conductor configured to supply power at a first current level when electrically coupled to the first conductor, the third conductor configured to supply power at a second current level when electrically coupled to the first conductor, and a first adjustable shelf carrying a first lighting device, the first adjustable shelf being removably mountable in one of the plurality of shelf mounting positions such that the first lighting device is electrically coupled between the first conductor and the second conductor.

1. A refrigerator appliance comprising: a cabinet having a temperature-controlled compartment defined therein; a first shelf ladder disposed at least partially in the temperature-controlled compartment providing at least a first and second shelf mounting position, the first shelf mounting position has a first slot and the second shelf mounting position has a second slot separated and spaced apart from the first slot, the first shelf ladder comprising a first bus conductor, said first bus conductor being electrically grounded, a second bus conductor, and a third bus conductor, the second and third bus conductors each having a first section spaced apart from a second section;a first adjustable shelf carrying a first lighting device, the first adjustable shelf having a mounting bracket with tabs configured to be removably mountable in one of the first slot and the second slot such that the first lighting device is electrically coupled to the electrical bus when the first adjustable shelf is removably mounted in one of the plurality of shelf mounting positions;a second adjustable shelf carrying a second lighting device, the second adjustable shelf being removably mountable in one of the plurality of shelf mounting positions such that the second lighting device is electrically coupled to the electrical bus when the second adjustable shelf is removably mounted in one of a plurality of shelf mounting positions;wherein the second bus conductor and third bus conductor are separated into a first section and a second section such that the first section is exposed in the first slot and forms a first independent circuit with the electrically grounded conductor when the adjustable shelf is removably mounted in the first slot and the second section is exposed in the second slot and forms a second independent circuit with the electrically grounded conductor when the adjustable shelf is removably mounted in the second slot. 2. The refrigerator appliance of claim 1, wherein the electrically grounded conductor and the second bus conductor are exposed in the first slot to form a circuit with the first lighting device when the first adjustable shelf is removably mounted in the first slot. 3. The refrigerator appliance of claim 1, wherein the electrically grounded conductor and the third bus conductor are exposed in the second slot to form a circuit with the first lighting device when the first adjustable shelf is removably mounted in the second slot. 4. The refrigerator appliance of claim 1 wherein at least one of the second bus conductor and third bus conductor is separated into a first section and a second section such that the first section is exposed in the first slot and forms a first independent circuit with the electrically grounded conductor when the adjustable shelf is removably mounted in the first slot and the second section is exposed in the second slot and forms a second independent circuit with the electrically grounded conductor when the adjustable shelf is removably mounted in the second slot. 5. The refrigerator appliance of claim 1 wherein the electrically grounded conductor extends along the shelf ladder between the first slot and the second slot and is exposed in the first slot and the second slot. 6. The refrigerator appliance of claim 1, further comprising an insulating housing at least partially surrounding the electrical bus. 7. The refrigerator appliance of claim 1 wherein the mounting bracket is configured to engage the first shelf ladder to cantilever the first adjustable shelf in one of the plurality of mounting positions. 8. The refrigerator appliance of claim 7 whereby the mounting bracket comprises a first tab configured to electrically couple to the first bus conductor and a second tab configured to couple to the second bus conductor when the first adjustable shelf is cantilevered in one of the plurality of shelf mounting positions. 9. The refrigerator appliance of claim 8 further providing that the first and second tabs of the mounting bracket are each electrically isolated from a body of the mounting bracket that supports the first adjustable shelf. 10. The refrigerator appliance of claim 8, wherein at least one of the first and second bus conductors is spring-loaded to apply force against the first tab when the first adjustable shelf is cantilevered in one of the plurality of shelf mounting positions. 11. The refrigerator appliance of claim 10, wherein the first tab is configured to scrape a portion of the first conductor and a portion of the second conductor as the first adjustable shelf is cantilevered in one of the plurality of shelf mounting positions.
