Transfer mechanism for transferring power between a utility source and a stand-by generator

A transfer mechanism for transferring the supply of power between a generator which generates power when started and utility source, comprising:

• a monitoring system for monitoring the power supplied by the utility source, the monitoring system starting the generator in response to a power outage from the utility source and stopping the generator in response to the restoration of power from the utility source;
• a plurality of relays, each relay having:
• a utility input;
• a generator input;
• an output connectable to a corresponding load;
• a movable contact movable between a first position interconnecting the utility input and the output and a second position interconnecting the generator input and the output;
• and
• a coil connectable to the generator, the coil urging the movable contact into the second position in response to the generation of power by the generator;
• a plurality of generator circuit breakers, each generator circuit breaker interconnecting the generator to the generator input of a corresponding relay;
• and
• a plurality of utility circuit breakers, each utility circuit breaker interconnecting the utility source to the utility input of a corresponding relay.
