We just installed a Xantrex Prowatt SW2000 inverter. I wish to have all outlet boxes on Tomcat to be supplied by inverter when not on shore power. Xantrex Inline Transfer Relay f/PROwatt SW has two input leads and one output line. One input lead has a male plug to be plugged into inverter's GFI receptacle. The second needs to be attached to input source. (Can this second be attached to main on breaker panel)?

Secondly can the output lead from the inverter be connected to the breaker that services the outlet box's?

Any help in this matter will be greatly appreciated.

Thanks

Gene, look at the relay as a switch. You now are wanting all of the power going to the outlets to come from the 110V source of the inverter, or the mains power. You do not want to power battery chargers, or water heaters.
You tap the 110 hot after the main breaker--and disconnect that lead to the outlets. Take the lead to the outlets, and that goes as an input to the relay box. The output from relay then goes to the breaker for the outlets. Your common and ground will all be tied together with the rest of the circuits.
 
Gene, Here's how we wired our TC. One panel handles shore power only loads like the refer, water heater and battery charger. The other is for Inverter pass through loads (all outlets). I left one half of one duplex outlet connected to shore power to power a dehumidifier. We used an Outback 2500w. Inverter

Roger & Dr. Austin;

Thank you for the reply. I'm not sure that it is necessary to have it switch automatically from shore power to inverter power. I originally had a line/cord from our old inverter tied directly to a single outlet that serviced the oven & coffee maker. My second thoughts would be to run a line from the inverter's GFI receptacle to the breaker that services the outlet boxes that I want inverter power to. In your opinion does that present a problem?

Thanks again

Gene;, if you back feed the inverter, you have a very good chance of blowing the main circuit board. (You do not want mains power to the output of the inverter, which would happen if you did not isolate the circuit.

What I did on the Tom Cat, was to put a new outlet on the under surface of the shelf on the top of Port back cabinet, with the outlet access on the surface. I split the outlet--one socket was mains 110, and the second was inverter 110. You did have to plug in the appliance into the socket which had the power at that moment.
