Hospitals always (?) have standby alternators, but what about, for

type of things battery powered nowadays? Indeed, are such things used
at all now? :-)

Do you seriously believe that any sensible person would arrange things
so that their very life depended on the mains power not failing over a
protracted time? If so, perhaps they are more eligible for the
"Darwin award" than the people in question.

All electrically operated life-support machines invariably have an
alternate power source that will switch in automatically in the event
of a mains failure.

Dream on!

Bill the emphasis is on "electrically operated life-support machines".
Maybe not in your home but in hospitals, .. yes. At Sea as well. I have
been very heavily involved in the Marine Electrical Design business and I
know that the "Back up"" power supply is paramount. Not talking of the fun
yachts swanking around the Med chasing the sun and flashing boobs here and
there, but real maritime stuff.

Ask me

Yes Mike, you are right, I was also right but thinking more of the home
based kidney support equipment.
