Auto-switching duplex module

A method for use in delivering power to a device having a power cord terminating in a standard plug, said method comprising the steps of:

• providing a module including a module receptacle for receiving said standard plug and a switch for switching a connection of said module receptacle;
• first connecting said module to first and second power sources;
• and
• second connecting said standard plug to said module receptacle.

A method for use in delivering power to a device having a power cord terminating in a standard plug, said method comprising the steps of:

• providing a first standard receptacle for receiving said standard plug, said first standard receptacle being selectively associated with first and second power sources via a switch;
• sensing a loss of power quality from one of said first and second power sources;
• and
• responsive to said loss, cycling said switch to provide power to said first standard receptacle from the other of said first and second power sources.

An apparatus for use in delivering power to a device having a power cord terminating in a standard plug, comprising:

• a first standard receptacle for receiving a standard plug;
• a first terminal assembly for interconnecting to a first power source;
• a second terminal assembly for interconnecting to a second power source;
• and
• a switch for selectively interconnecting said first standard receptacle to either said first terminal assembly or said second terminal assembly, wherein said switch is operative for sensing a power quality of one of said first and second power sources and for switching a connection of said first standard receptacle responsive to said power quality.
