that's about 2 km from where i work - will check it out , cheers

A 2300W kettle would draw approximately 20A on a 110~120V AC circuit, as most Canadian receptacles are on a 15A circuit breaker the breaker would trip every time you turn the kettle on (one would hope).

yep... but we consider V=IR and wattage is W=Vi
given its resistve heating we know R is constant we'll cal it Rc (25 ohms)

So for 240V = i x Rc which is the same as 120v = i/2 x Rc

as W = Vi at 240v ~ i=9.6A and at 120v ~ i=4.8A giving you a power consumption of 552 Watts


So you fit the "don't do this" as you have no clue.....

I think the two of you are answering different questions.

Mike, in your scenario you're plugging a UK kettle rated at 2300W for a 240V circuit into a Canadian 120V outlet. Sure, 2300W at 240V draws around 10A, and has a resistance of around 24ohms. The same heating element on a domestic 120V circuit would draw around 5A and consume only 600W.

This is why some members have commented that hair tongs etc take forever to heat up here - they're using only about a quarter of the power they'd consume on a UK circuit.

What ArthurBrit is saying is that you can't get a 2300W kettle in a Canadian hardware store, because 2300W at 120V would draw nearly 20A, which would trip a breaker every time you switch it on. Kettles for sale in Canadian stores typically consume around 1500W and draw around 12A or so. Which is why it takes longer to make a cup of tea here.

It was my interpretation of the reply to the UK 2300watt kettle by SchnookoLoly, but I can see now how I could have got the wrong end of that.

FWIW A 2300Watt unit (if you could buy one) could still run on 120v but you’d need a 20A socket, which aren’t actually that uncommon and even come with GFI built in [20 amp GFCI (T-Slot), 20 amp breaker and 12 gauge cable would meet Ontario building code]

When I first went to post I did start to write out ohms law and all the theory behind it, then I went into each example of having A British kettle in Canada versus a Canadian kettle with the same rating.

After about 6 paragraphs and still not being finished I read back what I had written and realized that this was a bit overkill for BE so just stuck to the first paragraph!
