Abstract

A consumer unit is provided comprising at least one current protection device. The unit is distinguished in that it further comprises at least one light associated with the unit, the at least one light being operatively connected to the at least one protection device whereby the at least one light is energized so as to illuminate the unit when the at least one protection device operates.

Claims

1-20. -20. (canceled)

21. A consumer unit comprising at least one current protection device wherein the unit further comprises at least one light associated with the unit, said at least one light being operatively connected to said at least one protection device whereby said at least one light is energized so as to illuminate the unit when said at least one protection device operates, such that said at least one light is arranged to be sufficiently bright to enable a user of the unit to find the unit at least by way of peripheral stray radiation derived from said at least one light when said at least one protection device operates.

22. A unit as claimed in claim 21, wherein said at least one light is operatively connected to all of the protection devices.

23. A unit as claimed in claim 21, wherein at least one light is operatively connected to just some of the protection devices of the unit.

24. A unit as claimed in claim 21, wherein said at least one light is associated with a corresponding electrical lighting circuit for a region wherein the consumer unit is situated.

25. A unit as claimed in claim 21, wherein said at least one light is battery powered.

26. A unit as claimed in claim 25, wherein the battery is a rechargeable battery charged from main power applied to the consumer unit.

27. A unit as claimed in claim 26, further comprising a trickle battery charger for charging the rechargeable battery.

28. A unit as claimed in claim 26, wherein the rechargeable battery is substantially immune to discharge memory effects.

29. A unit as claimed in claim 28, wherein the rechargeable battery is one or more of a nickel-metal rechargeable battery and a lithium rechargeable battery.

30. A unit according to claim 21, wherein the at least one light is included in one or more of the following locations relative to the unit:

a top region of the unit, a side region of the unit, a bottom region of the unit and substantially completely surrounding the unit at a peripheral region thereof.

31. A unit according to claim 21, wherein the at least one light is formed integrally with the consumer unit.

32. A unit according to claim 21, wherein the at least one light is mounted to the consumer unit.

33. A unit according to claim 21, wherein in operation, when the electrical circuit with which the at least one light is associated is de-energized by its corresponding protection device, the at least one light is energized by way of any suitable device and/or mechanism.

34. A unit according to claim 33, wherein the unit comprising a relay which:

in normal operation of the electrical circuit maintains a light switch associated with the at least one light in an open condition;

and when the electrical circuit is de-energized, operates to close the switch thereby energizing the at least one light.

35. A unit according to claim 21, wherein switch means is provided to energize the at least one light in an event of a cover of the consumer unit being removed or lifted for maintenance or inspection purposes.

36. A unit according to claim 35, wherein a switch arrangement similar to that used in a domestic refrigerator is used for providing the switch means.

37. A unit according to claim 21, wherein the at least one light is arranged to operate in an intermittent flashing mode when energized in order to preserve battery charge and also help a user locate the consumer unit.

38. A unit according to claim 21, wherein the consumer unit also includes an intermittently-bleeping acoustic sounder to assist the user locate the consumer unit in an event of one or more of the electrical circuits being isolated from the main supply by way of the consumer unit.

39. A unit according to claim 21, the unit further comprising a test facility for allowing the unit to be periodically tested for establishing at least one of:

to verify that the battery is charged;

the at least one light is functional; and

to check that an acoustic sounding device associated with the unit is functional to emit acoustic radiation.

40. A unit according to claim 21, wherein the at least one light overhangs the consumer unit to improve illumination thereof.
