Probably some fail-safe, some reliable. I think that this is why
'safety' involves risk-assessment, not just meeting standards.

In my early days in product safety, safety was prohibited from relying
on conduction in a vacuum, gas, or semiconductor.
Today… we rely on semiconductor current limiters and similar devices,
e.g., GFCI control circuits.
Are such limiters and control circuits fail-safe devices?
Or, are they “reliable” devices and circuits where their lifetime is
expected (proven) to be greater than the host equipment?
