Abstract:
1. A transfer system comprising: an energy meter comprising an input structured to receive a first power source, and a power output; a transfer switch comprising a first input electrically connected to the power output of said energy meter, a second input an output, and a mechanism structured to transfer one of said first and second inputs to the output of said transfer switch; an automatic disconnect device comprising a first input structured to receive a second power source, a second input, an output, and a mechanism structured to electrically connect or disconnect the first input and the output of said automatic disconnect device responsive to said second input; a detector structured to detect presence of said energy meter in said input structure and to output a corresponding signal to the second input of said automatic disconnect device; wherein said energy meter is a utility energy meter further comprising a meter socket and a removable meter portion; and wherein said detector is structured to detect presence of said removable meter portion in said meter socket; and wherein said detector comprises one of a normally closed contact that opens upon insertion of said removable meter portion in said meter socket, and a normally open contact that closes upon insertion of said removable meter portion in said meter socket; and wherein said detector outputs said corresponding signal to the second input of said automatic disconnect device through one of said normally closed contact and said normally open contact.
