What's the difference between a manual transfer switch and an automatic unit? With a manual transfer switch, when the power goes out, you need to start your generator, and connect it to the transfer switch. You then need to switch your house over to generator power. When the utility power is restored you need to switch your house back to utility power, and turn off your generator.

With an automatic transfer switch, everything is fully automatic. When the utility power goes out, the transfer switch signals your generator to start. Once the generator is running the transfer switch automatically connects your home or business to the generator. When the utility power is restored, the transfer switch reconnects your home or business to the utility. Then it turns off your generator and waits patiently for the next power outage.
