Abstract

An electric power distribution system includes a first power distribution apparatus for distributing power to individual load circuits from a main power source and a second power distribution apparatus adjacent the first apparatus. The second panel has a base, an electric power distribution conductor supported by the base for providing electric power from the alternate electric power source and a load circuit selector site on the base and is operable to supply power from the main electric power source and the electric power distribution conductor to a signal-controlled selector installed at the load circuit selector site.

Claims

1. A method for distributing electric power, the method comprising distributing electric power from an alternate electric power source to a plurality of selector sites and supplying electric power from said alternate electric power source or from a main electric power source to at least one load circuit, through a signal-controlled selector at at least one of said plurality of selector sites.

2. The method of claim 1 wherein distributing comprises conducting current on an electric power distribution conductor in proximity to said plurality of selector sites.

3. The method of claim 2 further comprising supporting said electric power distribution conductor and said plurality of selector sites on a base.

4. The method of claim 3 further comprising supporting a plurality of signal lines on said base to permit said plurality of signal lines to carry control signals to respective signal-controlled selectors.

5. The method of claim 4 further comprising providing at least one control signal for controlling at least one signal-controlled selector.

6. The method of claim 5 further comprising supporting on said base a controller operable to produce said at least one control signal.

7. The method of claim 5 further comprising supporting on said base a connector for receiving said control signals from a remotely located controller.

9. The method of claim 1 further comprising providing a plurality of overload current protection mounting sites in proximity to corresponding selector sites to provide for mounting and connection of overload protection devices in series with said alternate electric power source and respective selector sites.

8. The method of claim I further comprising providing overload current protection to said load circuit when electric power is supplied to said at least one load circuit from said alternate electric power source.

10. An apparatus for distributing electric power to a load circuit from a main electric power source and an alternate electric power source, the apparatus comprising:

a base;

an electric power distribution conductor supported by said base for providing electric power from said alternate electric power source; and

a load circuit selector site on said base and operable to supply power from said main electric power source and said electric power distribution conductor to a signal-controlled selector installed at said load circuit selector site.

11. The apparatus of claim 10 further comprising the signal-controlled selector installed at said load circuit selector site, wherein said signal-controlled selector is operable to selectively connect the load circuit to said main electric power source or to said electric power distribution conductor in response to a control signal.

12. The apparatus of claim 11 further comprising a signal line supported by said base for carrying said control signal to said signal-controlled selector.

13. The apparatus of claim 12 further comprising a controller for providing said control signal for controlling said signal-controlled selector.

14. The apparatus of claim 13 wherein said controller comprises a processor circuit supported by said base.

15. The apparatus of claim 13 further comprising a means supported by said base for receiving said control signal from a remotely located controller.

16. The apparatus of claim 10 further comprising at least one overload current protection mounting site on said base and associated with said load circuit selector site to provide for mounting of an overload current protection device.

17. The apparatus of claim 16 further comprising an overload current protection device mounted at said overload current protection mounting site.

18. The apparatus of claim 17 wherein said overload current protection device comprises a circuit breaker.

19. The apparatus of claim 10 wherein said base supports a plurality of overload current protection mounting sites associated with separate respective load circuits.

20. The apparatus of claim 19 further comprising a plurality of signal-controlled selectors, each one being installed in a respective load circuit selector site.

21. The apparatus of claim 20 further comprising a controller for providing respective control signals to said plurality of signal-controlled selectors.

22. The apparatus of claim 20 further comprising a connector for receiving respective control signals, and signal lines on said base for communicating said control signals to said plurality of signal-controlled selectors.

23. The apparatus of claim 20 further comprising a plurality of overload current protection mounting sites on said base, each overload current protection mounting site being associated with a respective load circuit selector site to provide for mounting of a respective overload current protection device in said each overload protection mounting site.

24. The apparatus of claim 23 further comprising a plurality of overload protection devices, each one being installed in a respective overload current protection mounting site.

27. The apparatus of claim 26 wherein said base includes a printed wiring board and said means for supplying power comprises traces on said printed wiring board.

28. The apparatus of claim 27 further including mounts connected to said traces and arranged to form a selector site to facilitate mounting of a signal-controlled selector thereon.

29. The apparatus of claim 27 further including a plurality of mounts and traces arranged to form a plurality of selector sides on said base to facilitate mounting of a plurality of respective signal-controlled selectors.

30. The apparatus of claim 29 further comprising means for carrying control signals to said plurality of respective signal-controlled selectors.

31. The apparatus of claim 30 further comprising means for providing at least one control signal for controlling at least one signal-controlled selector.
