Must admit i'm looking at the self resetting RCD purely from a personal
angle at present and agree there could be times someone may believe a
circuit is dead - though i'm assuming if a fault occurs its check to see if
its clear and then resets - if the fault lasts longer than milliseconds i
guess it wont reset, as this would indicate a man and a pickaxe still stuck
in the cable etc.

Dont know for sure but will find out when i get one - i've now been

they are not in the UK yet, but we will be getting one of the first ones to
try (on my house of course). I'll keep you posted when i've tried it out.

I can see a lot of benefits to nuisance tripping problems, and i'm sure if
its 100% safe it could catch on - especially as some developers are going
for 100% RCD coverage of the mains boards rather than split, thus

nuisance tripping with lamp failures sometimes taking out RCD's etc.

Dean,

I think it makes a lot of sense to put such devices on a UPS. The main
advantage being that you will remove brownouts and sudden on-off-on
transitions.=20

If your not looking for cover during an extended outage, which could be
several hours, then enough capacity to allow a controlled shutdown in
software would suffice...

As with most things bigger is better, your limiting factor will be
accommodation. Look for a second hand unit that can shut down the PC with a
serial or USB interface (10 minutes should be ample, you could delay for an
additional 15 minutes to cover 90% of outages) something between 1 or 2
KVA...

Interested to see you mention the self resetting RCD. I fist saw these used
in Spain for remote sites which suffered from lighting strikes. My concern
would be Circuits energising automatically if someone thought it
dead/isolated...

Due to increasingly regular powercuts in our village (the last one
knackere=

my HTPC) - i was thinking about putting a UPS on DVD/Sky+/Amp/HTPC setup.

Is anyone doing the same - if so what size UPS does the job.

I'm just thinking of about 15 mins of uptime which will usually overcome
th=

worst outages - but makes sure everything is in sync when SWMBO next goes
t=

use it all :)

I'm also about to try out a self resetting RCD if anyone is interested - we
get tripping when v.windy (overhead supply), and i've stumbled across an
RC=

than when tripped checks if all circuits are clear, and then resets itself
!!
