Aside from screwing up which leads go where, once it's connected a transfer
switch is idiot-proof - one or the other source, but not both. The biggest
problem is size, though Cooper (recently was Eagle) makes a 30 A AC DPDT
toggle switch, #3036V, that is commonly used to double-feed water heaters or
deep wells. Though that would be overrated for your app, it could handle
shore power faults.

Similar issue to using a generator at home.
Before the electric utility (util) will allow you to connect a home
generator to your house wiring, you must install an approved gen/util
switch. That gen/util switch will connect your house wiring to EITHER the
gen or the util, never both together. You might install such a switch on
your boat to make the Inverter/ShorePower selection. Because, in this
case, the consenquences of switch failure or wrong wiring are severe, the
job is for professional electricians, not a high school grade hobbyist.
There is more involved that just "figuring out the circuit".

The inverter I am interested in only has regular 110V outlets, not a
hardwire option. Why couldn't I make up a cord with male plugs on each
end to go from the inverter to my A/C system? This would wire up my
whole system from the inverter, right?

And what happens when I forget to unplug it and hook up to shore pwer?
