For the NA 120v voltage standard the figures are : 500w unit I=4.17A (approx), 2kW, I=16.7A (approx), & for 3kW, I=25A(exactly)! --- End quote --- I don't know about the rest of the world but in the US normal AC outlets are usually rated for 15 amps however kitchen outlets are rated 20 amps (all at 120 VAC). Does anyone else in the EU, UK, etc do that? FWIW with regard to the power available: electric kettles aren't that common here either. We just use a plain kettle on the stove top. |

everyone switch to CFLs. 5 years later : ban cfls, they contain mercury. try getting rid of them now. you can;t throw them in the trash , nor in the recycle bin. you have to give them with the dangerous goods. |

Electric kettles are significantly more efficient than stoves. |

The UK has a ring main system, with an MCB rated at 32 amps, but the individual socket outlets are rated at 13 amp with all the plugs 13 amp fused. On the average 3 bed house, which is much smaller than the average US property, there will be a ring main for each floor, as most houses are 2 story. Bare in mind though, our mains voltage is 240V so a 13 amp socket will support 3.1 KW. Our kettles are generally rated at between 2-3KW and you'll struggle to find a home or business without one!! Actually, it's a major problem for our power grid, because the nation tends to watch sh1t soap's like sheep, in their millions and when an ad break comes on, everyone puts the kettle on for a coffee or cup of tea, this results in a huge load spike for the grid, so they have to watch the TV schedules and plan accordingly!! That must now be less of a thing or becoming so though, as a result of catch up TV options. |

Those things went on for years and years, with good efficiency, and pleasant illumination. Their only downside was their slow start, and the classic negative for any fluorescent lamp - don't use them in places where they have many short runs, like domestic bathrooms. --- End quote --- Really? I have some nigh-on 7 year old Costco LED bulbs that were about £8 for 3 x 7W LED - warm white, instant start, and by my estimation about as bright as they left the factory. CRI is >80, which is better than most CFLs. They have probably done 15,000 hours already. CFLs can't beat modern LEDs. |
