Several hundred dollars worth of 12 gauge Romex and accessories were
involved. Simple things like putting the garbage disposal, microwave,
and toaster oven each on their own circuits make a big difference.

Romex is roughly what we call Twin and Earth in the UK?

What you're saying is radial circuits are commonly overloaded in some way?
All of those (and more) would work just fine on the one UK circuit.

Current price for 2.5mm TW&E in the UK (for final ring circuits) is about
45 gbp per 100 mtrs before tax.

Yes, 12 gauge Romex is just about equivalent to our 2.5mm twin and
earth in wire gauge. The problem of course, is that in the US it is
required to handle twice the current that we use for the same load.

About the same as if we used lighting spec cable for our sockets. Not
a great plan, I'd say.

Oops, I forgot. With a ring main we are effectively using it doubled
up - two runs in parallel. That means that we only load our domestic
cables a quarter as much as they do in the US. No wonder we don't
suffer from voltage sag here when we turn things on.

#12 AWG is used for 20A circuits. (Outlets) How is that 1/4?

#14 AWG is used for 15A circuits. (Lighting)
