Winegard Wall Plate Power Supply
Like most rvs, I have the above antenna connection with 12v outlet. I am wanting to hookup a 400 watt inverter in the cabinet where the outlet is located. I realized though that the outlet is only g...

Guys, if it's a 400 watt inverter that's only 3.33 A at the output.
I will speculate that the invert with it's overhead inefficiencies shouldn't draw more than 4 A max with 400 watt output, which they normally are specified with "peak output".
I'll guess that the 12V load for the average small flat screen will be 1 amp or less. I have a 23" that dissipates only about 24 watts.
The old CRT TV's pulled a lot more current than the modern flat screens.
If you load it up you should smoke the inverter long before the outlet.
Put an amp meter on the 12 volt line and try it. Then you'll know for sure what it pulls.
