Inverter out -- extension cord?
I have read that some use extension cord as the ac out on their inverter. We plan to run a flat panel tv, dvd player, or satellite box with our 600 watt inverter. I need to run about 40 feet from the ...

A pair of common DPDT 120vac relays rated at 30 amperes can safely pass sixty amps and be used as a transfer relay. Wire them individually, one relay, both poles for the hot, the other relay both poles carries only neutral.
On the Kelley, I used six relays so as to provide 60 amperes capacity 3 phase 240 power. Those relays had 240 volt coils. A GE transformer converted single phase down to 60 amperes of 120 volt AC. When they were connected to the dock, and needed refrigeration they cranked up the Allis Chalmers 60 KW gensets and paralleled them. Shore power switching was automatic. The shore power cord was 4/4 cable, a little bulky.
There is ZERO reason to be forced to settle for garbage transfer switch relays, IMHO. The integral relay in my Trace 4024 has been neutered because it is a joke compared to the 6" X 6" box sitting next to the inverter.
