Re: Electric appliances help
Provided the current doesn't leak to earth, then its perfectly possible for an ELCB to continue to happily feed current up one arm and down the other, an ELCB will not trip under those circumstances. They measure current imbalance between the L and N, if the difference exceeds some nominal amount, often 10..20mA, the circuit opens. The expectation is that the imbalance is flowing to earth via you.
The IEE regs only seems to mandate ELCBs on certain circuit types, and the same ones as the US regs have mandated ELCBs

Power distribution is also quite different, i have a friend in the uk who was sort of the 'wichita lineman' in his job, High tension lines in the UK operate at between one third and 2/3 of 1,000,000 V, I believe in America it somewhere different but I have no clue whether the one is superior to the other. I know we tend to use more tunnels for it.
It depends on the lengths of the lines, and the loadings. The USA uses quite a lot DC interconnections these days, as we do with the Channel interconnector and the new Scandanavian connectors. The multiples and ratios are well controlled and international - and the USA uses them too.

Re: Electric appliances help
There was the amusing day an electrician connected one phase positive to negative in a power dist room, and caused [500 machines?] to start smoking regardless of on or off or switched off at the wall socket - but then he was operating years before elcb's when i think about it. Same guy later seen drilling into switch boxes to affix 'dangerous 415 volt' labels - i considered giving him double sided tape but we decided the possibility of a darwin award for him was overwhelmingly a superior choice...

Re: Electric appliances help
There is no "positive" and "negative" in an AC system. He MIGHT have connected a Phase to the Live terminal and a Phase to the Neutral terminal though. That would put 415V out.

Re: Electric appliances help
In your language, he connected a 50 amp live or positive wire to a neutral or negative terminal post, causing instant bad karma to anything plugged into the phase regardless of switch state.

Re: Electric appliances help
Any given phase swings positive and negative wrt neutral and ground, so which is it ?

Re: Electric appliances help
So my electrical knowledge and gadget/tech knowledge are both about zero.
As long as my electrical item or its charger says 90-240v or similar I can use it in the US with an adapter? From a quick hunt around the house I can see that my Sonos and my laptop charger both have the right credentials but my nutribullet does not. So kitchen equipment has to go but the rest is ok with an adaptor. Is that about right??

Re: Electric appliances help
About, your nutribullet is probably quite powerful - so not suitable/cheap enough for them to make a variable input supply, cheaper for then to just make it with different motors or different wiring [do not attempt to change it...]

Commonly called an iec or kettle flex, but make sure it fits, there are variable designs...

Yeah, british plugs with adapters do not play well with US sockets. And you can probably pick up a new cable for less than the price of a plug adapter.

Re: Electric appliances help
Both ends of the cable have specific names. For reference, "kettle style" is C13, figure 8 is C7, and cloverleaf is C5. For the wall socket, you want NEMA 1-15 (2 pin unearthed) or 5-15 (3 pin with earth connection).

Re: Electric appliances help
Oh yeah, americans arent allowed to make their own sometimes are they? Ie can you buy a plug by itself and just cut the flex, strip the conductors, fit the flex and screw it together as we would do in the uk?
We also have adapter plugs in the uk when we import stuff, a us or euro plug inside, clipped into a uk plug. Maximum luck would be to find you had one of these.
