The original (very generic) title):
Government to go “further and faster” in becoming energy secure
The Energy Secretary outlines measures to protect consumers and make Britain energy secure.
They are speaking of panels in the 800W range which you can just buy , mount in front of your balcony or on top of your carport, and plug into a wall socket.
These things are wildly popular in Germany. The do not generate a lot of power, but armotize in about three years and save real money. (Depending on how old the metering technology is, they can also make the power meter spin backwards, which I think is only fair considering how much households pay for kWh, compared to energy-hungry companies, which get most of the the massive cost savings from renewables but don’t pay for the necessary upgrade of the grid).
But doesn’t the plug based amp mitigate the very problem you’re worried about at the appliance level?
Isn’t that what I wrote?
It’s an imperfect mitigation, though - the typical fuse in the plug is 13A, so you only need two fully loaded sockets and you’re already in trouble. Fortunately these days nobody is plugging in 3-bar electric fires or immersion heaters, and it’s quite hard to find those kinds of loads outside the kitchen, so it’s less of a practical issue, sure. (This is also why UK electrical code recommends that any load greater than 2kW should be given its own radial instead of being plugged into the ringmain. It’s not unusual for the kitchen to be on a dedicated radial (or two) even if the rest of the house is on rings.)
(You could instantly make UK wiring a lot safer by just eliminating the over-rating of the breakers - i.e. if you have a 24A ring, put a 24A breaker on it. In the olden days that would probably have caused nuisance trips (3-bar fires and all,) but these days I doubt anyone would notice.)
Your implication in how you wrote was that the appliances are at risk. However the built in fuses in the plugs should mitigate that
One thing about the old standards is that, as you said previously, it might trip more with less efficient devices, however it was also a case that it wasn’t trip switches, but fuse boxes with physical fuses. So it wasn’t just a hassle, they needed replacement at expense, and a dependency on adequate stock.
Those days are gone, so yes, modern standards should be updated.
