| 1456612 | 2018-12-18 06:53:00 | Why are our plugs here so crappy? The pins are flimsy and break far too easily. | gary67 (56) | ||

Shortage supplying the market to maximize the price is a way of life here. Competition in the marketplace, LOL, is mostly illusory. And of course that old saw: "we're a sparsely populated, mountainous little country, with long trade routes, that's why prices are high." |

I guess that's fair enough, as the overload cutout failed after a couple of years in the ones I used at full load with a jug. In the same location, an Arlec lasted about 15 years before it started randomly tripping. It actually still works fine for a computer instead, now, despite the plastic being suntanned to a golden brown that puts Trump to shame. The amount of power (measured in amperes - usually abbreviated to amps) is dependent on the amount of power an appliance uses. The usual amount in your household wiring allows for 10 amps. So if there is a leak in the power and you receive a shock it will be at least that amount and is not dependent on the fact that it has an earth pin or not. You will receive enough to give you a very good shock which may or may not kill you. A very good idea of the amount of power used was shown to me when somebody showed me what happens when you short out a car battery. The screwdriver that he used glowed red hot with the amount of power flowing through it. That, he said, was a lot more power than that which flowed through your house wiring, and it was a very good example of the amount of power available in a 12v battery. See en.wikipedia.org Power is not measured in amperes, it's expressed in Watts, and is calculated by the product of current (amps) and voltage (volts). You can't get "a leak" in "the power", that makes no sense. Despite the water pipe analogy used throughout high-school physics textbooks, a live wire does NOT act the same as a garden hose. A car battery typically has a CCA (cold cranking amperes) rating of say 300-500A x 12v = 3600-6000 Watts. (assuming the battery's voltage does not drop when supplying cranking current - which it does) Your hot water cylinder alone will easily run at 3kW, which is approaching a small car battery. Now, since your house supply is fused at the pole for probably 50 to 100A, you've got the capacity for maybe 24kWatt or more. While a car battery might supply more current (over a short period of time until it goes flat), your house supply can definitely provide more energy overall, and continuously. In regards to the screwdriver "trick" (deathwish is probably more appropriate, especially on a freshly used/charged and potentially still off-gassing battery) - try turning on all your stove elements at once :) You must be doing something wrong - I have never broken a pin in my life. (except when I have done something incredibly stupid - and I am not saying what that was) I managed to break one off a phone charger by standing on it, but it was the plastic housing which broke, not the actual pin. |
