RE: UK Voltage

["Ian Lowe" <ian@xxxxxxx>]

Thanks for the politics Martin,
Now would you mind very much not doing it again?

This group is about Home automation, and we likely have wildly different
views on
religion, politics and dress sense. Which are *all* of zero relevance to
our
discussions.

Cheap digs at Europe? No Thanks.

As it is, European utility companies *HAVE* changed their supply voltages,
>from
UK companies have not, probably for the same reason.

The only side effect for us is that we get much less life from our
lightbulbs.
(and probably other appliances)

Phillips who(in common with other lamp manufacturers) produce a single 230V
product for pan-european use
state:
"A 230V lamp operated at 240V will only achieve 55% of its life.
Tests have been carried out on a sample of some domestic ceramic
pendant fittings with a single 60W lamp. The user safety was
infringed at two locations at 240V - the lamp cap and the
bifurcation point. It was infringed at four locations on the
lamp/luminaire at 250V - the lamp cap, the bifurcation point, the
cord grip at the entry to the lamp holder, and the cable insulation
under the cord grip. The UK supply voltage does at times fluctuate
as high as 250V."

Ian.

Voltage didn't change anywhere....just the spec, now single spec across
euroland!! Typical Euro nonsense.

Now spec is something like 230V +/- 10%

This makes sense as then 253V would be a cutoff point which is what your
UPS is doing.
