Nominal Voltage

Les Macaulay · May 12, 2014

Why has nominal voltage gone from 250Volts back in the good old days, to 240Volts, several years ago, to 230Volts more recently?

What is the legal max and min tolerance in the 230Volt level?

Its the same old same old, less volts for your money:yesnod:. The DNO wants to keep putting up the bills, but wants you to have less volts for it. Wait till they suss out that by giving you less volts, they give you more currents, so they will put the bills up even more. Anyone noticed that most 20 packs of smokes have come down to the £6.00 mark ( i only use the cheap ones) but they only have 18 or 19 smokes in them. Its called rip off Britain.

240V isn't 'recent', it has been around for much of the time for which the UK has had a single standard voltage. Before that time you would have found 100,105,110,120,200,205,210,220,230,235,240,250 and possibly others all in use in different areas, some AC, some DC. To date, 240 has been the most standard standard, and it still is albeit under a different name.

This was the point I was making earlier however it is safer the lower they make it in the plus side

You mean like the American system with its 120V being so much safer than our 240V?

(We really need a sarcasm font!)

Has it?

Last time I checked 433V Ph→Ph = 250V Ph→N

You will never see it above 230

Are you sure?

I’ve just realised why there’s a discrepancy between actual and nominal voltage.

Several years ago the EU and IET phoned the DNO’s to tell them of the change.
They’ve been on hold ever since.

By the way if ukip came to power would we go back to 240v and red and black wiring colours?! Not a deal breaker considering they are otherwise a bunch of nazis...

what a load of old crap.

you clearly dont know what your talking about on such matters so kindly just shut up.

micknew · May 19, 2014

Vote UKIP, get of the EU then we can make our own rules.

Guys stick to the point of the thread, without the politics please
