Ireland went to the effort of changing from Schuko to BS1363, and that was on technical merits (safety in particular).

Even better, Prescott could be rendered down, although what the resultant blubber would do to the environment I shudder to think.

That may be so, but the other just followed irrespective of whether it was good or bad. Is it happens the 3 pin plug is probably the best of a bad bunch.

The ignorance of this one holds no bounds. He is saying that if there is an earth fault the RCBO will only trip when the current rating is exceeded. Which defeats the purpose of an RCBO.
- If there is an over-current fault on the circuit it will operate the overcurrent detection part of the device, which will trip the RCBO.
- If there is an earth fault on the circuit it will operate the earth fault part of the device. This will also trip the RCBO.
The above two points are mutually exclusive.
There are two separate sensing circuits contained within the one RCBO device, operating a single activation device to interrupt the current flow on live AND neutral.

Where have I said that? Please explain how and where an earth fault occurs "With a current path only from line to neutral"?

And you would improve on the plug design how exactly?

Where did he say that? I think you have reading comprehension issues. Peter made no reference to earth faults.
Odd that you claim this is not the case with a separate MCB and RCD then. I refer to your assertion that a blowing lamp will trip a RCD.
So which of your pronouncements is wrong then?
No, three actually; Thermal (overload), Magnetic (fault), and Current Imbalance.

And "the rest of the world" elected you as a spokes muppet when exactly?
And FYI, the rest of the world does not come only from Essex.

If I was doing R&D it would be the best. The problem is that they are constrained by having to have a link with previous designs. For E.g, why didn't they change the design to round, which is better for contact, instead of flat pins on the last update? Why? Because millions of sockets are flat pin that is why.

That will have to be a exercise in conjecture for our readers.
Strange really... Previous sockets were round pin and not flat.
Why do you assert that round is better than flat pin?

They aren't mutually exclusive, as they can both happen together due to the same failure (e.g. a heating element which shorts to earth halfway round will generate an overload and an earth fault).
You missed:
- Fault current protection.
A few RCBO's (e.g. Merlin Gerin, IIRC) also include:
- Polarity reversal tripping
- Loss of neutral tripping
You can buy RCBO's which switch the neutral, but they aren't normally used in this country because they use up 2 positions in the CU, and neutral switching isn't required.

They are. One is not dependent on the other.
"isn't required"? By regs no, but safer when tripped as all is off and when working on the circuit too.
