If it was only an assertion, then you responded with technical facts
as to why it is not so. David Hansen posted a denial without a
single supporting fact or reason. IOW David Hansen posted the
assertion - as demonstrated by no citations, no numbers, and no proof
that RCDs provide no human safety.

Meanwhile, RCDs are routine in other nations for bathroom safety.
This necessary because - just another fact, David - humans are at
greatest risk when wet.

But David - show us you have basic knowledge. Show us how the RCD
does not protect human life. The only assertion is a 'nay saying'
propaganda statement - devoid of any technical facts.
