Installing Transfer Switches in AC Circuits

If you are using another AC source on the same circuit as the PROwatt 1000, install a transfer switch to ensure that the sources never power the circuit at the same time.

The switching mechanism can be as simple as a plug that you insert in the desired AC power source. See Figure 3-2.

You can also use a manual or automatic transfer switch. See Figure 3-3. A transfer switch is a double pole, double throw (DPDT) switch that switches both the line and neutral wires to the AC distribution system from one power source to the other. They are commonly used to switch between a generator and utility power (shorepower).
