Twenty four US states are now considering legislation to allow small, plug-in solar power systems that connect directly into a wall socket. (www.nytimes.com)

I'm a little wary of plug-in solar in the US. Some of the bills propose allowing 1200 watt panels which can overload wiring depending on what else is on the circuit and how in the wall wiring is run. Limiting plug-in panel wattage to, say, 400 watts might be necessary

I think you need to learn how electric circuits work.

That's an awfully snarky reply to someone who is correct.

I've had more than a few classes on circuits throughout my schooling, from high school physics to my mechanical engineering college coursework. Please enlighten me as to where my logic is flawed.

Two sources wired in parallel can supply more current than either individual source can supply on its own. The wiring on each parallel branch will have identical voltage, and the converged branch will carry the sum of the currents. Total load of 20 amps exceeds the capacity of the wiring, breaker doesn't see the full load and doesn't trip.
