Of course that's the type I'm talking about, hence me referring to 30mA, not 15A. In the UK, the whole house is protected by such things, why wouldn't it be? This is why I use fuses.

You folks are talking apples, oranges and pomegranates

In UK, Oz and NZ they have an RCD that looks for ground faults in the
range of 30ma and disconnect the whole panel.
This is a typical NZ panel.
The red breaker is the main, the blue the RCD and the rest are branch
circuit breakers.

In the US we only protect single branch circuits or individual loads
with a GFCI but that is at 5ma.
When we see 30ma protection, it is called "ground fault protection for
equipment" because we think 30ma is too high to protect people.
One thing you must keep in mind is 5ma might not kill you but it can
still cause you to fall off the ladder.

I see, so you're being way too safe again. Bunch of pansies is what you are. When we put in RCDs at 30mA, it was advertised you wouldn't even feel it when you touched the live. I touched a live wire on my mower without any breaker on it (a rat had chewed the flex) and had my bare feet on the ground. I jumped SLIGHTLY and said "Aya*******!" Having that on a trip would have reduced it to un-noticeable..

A military pilot called for a priority landing because his single-engine jet fighter was running "a bit peaked."
Air Traffic Control told the fighter jock that he was number two, behind a B-52 that had one engine shut down.
"Ah," the fighter pilot remarked, "The dreaded seven-engine approach."
