Abstract

A current limiting system in accordance with the present invention comprises an accessory or canopy mount device that is permanently installed between a source of electrical power 1 and a track lighting system 2. The system may be installed integrally with a track lighting system to supply power to a plurality of lighting tracks from a plurality of power sources or circuits, as desired by a user or lighting designer. The system may also be configured to be compatible with a wide variety of track lighting system power tracks and is difficult to remove once properly installed, thereby making it tamper-proof

Claims

1-25. -25. (canceled)

26. A current limiting system for limiting the electrical current supplied by a source of electrical power to a track lighting circuit comprising:

at least one conditional current limiting device to limit electrical power to said track lighting circuit in an over current situation and otherwise output a received voltage substantially unaltered;

at least one lighting track connector electrically coupled to said at least one current limiting device; and

wherein said lighting track connector is securable to said track lighting circuit.

27. A current limiting system for limiting the electrical current supplied by a source of electrical power to a track lighting circuit as claimed in claim 26 comprising:

a plurality of current limiting devices; and

a plurality of lighting track connectors.

28. A current limiting system for limiting the electrical current supplied by a source of electrical power to a track lighting circuit as claimed in claim 26 wherein said lighting track connector is capable of being secured to a current-carrying lighting track.

29. A current limiting system as claimed in claim 26 wherein said current limiting device comprises a visual load indicator for monitoring the electrical power supplied to said circuit.

30. A current limiting system as claimed in claim 26 wherein said visual load indicator comprises a plurality of light emitting diodes indicative of predetermined amounts of power supplied to said circuit.

31. A current limiting system as claimed in claim 26 wherein said current limiting device is sized to limit electrical current to a predetermined maximum based upon the length of track secured thereto.

32. A current limiting system as claimed in claim 26 wherein said at least one current limiting device comprises a circuit breaker
