Why not just have one huge GFI for the entire electric grid. Then
just hire a guy to sit there all day and reset it every 10 seconds.
But, hey, look at the bright side of this. You would not need a
flasher on your christmas lights...... :)
What does the word "they" refer to - a "whole house GFCI" ??
In actuality, there is no such thing that could be set up
to protect only receptacle circuits. You can protect 1 branch
circuit at a time with a GFI breaker or a GFCI receptacle.
With a GFCI receptacle, you can also protect only a part of
the circuit. A GFCI receptacle can be installed such that it
protects all outlets wired downstream of it, or only itself.
There's no such thing as a "whole house GFCI" in any event.

Safety, in that some circuits, that ordinarily would not pose an
electrical shock hazard to people, or would be catastrophic if they
were to be accidentalle de-powered, such as lighting,
heating/coolling, food refrigeration, and fixed appliances in general.
Ok, so if I understand it, "whole house" really isn't
whole house - its all the receptacle circuits in
the house, in the context you use.
Does this "whole house" GFI trip at 5 mA fault current?
For the record, I'm talking about ground fault protection
for people. If the "whole house" protection trips at a
level that could be harmful to people, then it is not
the "best thing", as we are discussing in this part of
the thread, which started with:
"It would be incpnvenient to wait for the Poco to reset it.
The best thing would be a whole house GFCI, as is oftern used
in most of the rest of the world." from Gary Tait's post.
We use linear circuits here in the USA. In many countries with 240v "mains",
the circuits are "ring."
From a 40a breaker (1 pole) they'd run a #12 (good for 20a) out to the 1st
receptacle, then to the 2nd, until the last receptacle on that "ring" is
reached, then, continue on back to the SAME breaker.
The neutral does the same thing. All this without ever splicing or cutting the
"ring main" conductor.
