This is a very convenient feature that I just learn after having a professional electrical audit to my boat! 2007 34 Mainship
Basically you can use two different 30amps shore power connectors to power you boat at the same time (shore power 1 and shore power2) this is convenient when running AC, water heater electric stove or any other simultaneously with out going over 30 amps on each shore power line. When doing this you should have the transfer OFF. Otherwise you will be overloading your system with 220 volts.*
When using only ONE shore power connector (either 1 or 2) , you transfer the power to the other line by switching the transfer to ON. Now you are using 110volts on *one 30 amps cable for all your electrical needs. If you abuse the load you could overheat the cable, or shut off the breaker at the marina or your electrical panel.*
In other words by turning the transfer to "OFF" you are splitting your electrical panel into two independent panels.*
I hope I made may self clear as I'm not to electrical savvy !

Good luck!
