Ejector-Plug
Automatically ejects when potentially dangerous | |
Most electrical accidents happen with everyday items; hair dryers, shavers, toasters, kettles etc. So how about constucting them with intelligence...So whevever theres potential danger (over heating, crossed wires, moisture etc), the device detects it and sends a signal to the 3-pin plug in the wall
socket where a spring ejects the plug out of the socket. voila! it's now as electrically hazzardous as a banana.
It's the amps, not the volts.

Funny how I've tried dropping a banana on my foot and it didn't really hurt, but a microwave oven on the other hand ... |

They're called GFCI outlets. Ground Fault Circuit Interupts. The theory behind them is that the circuit can detect stray current extremely rapidly, and isolate the outlet in a split second. |
|

can I not have one of these on my life support system please.. at least get it to SMS me witha Y/N shut down decision. |

Isn't this what the fuse in the plug is for? Or are plug fuses another strange foible of the UK wiring regulations that noone else has? |
|

We have earth leakage circuits as well. Unfortunately ours trips occasionally for no reason*, usually in the middle of Eastenders. |
|
| |
* well presumably because of an Earth leak. I just can't work out where from |
|
| |
I would think that the GFCI circuits are safer. An ejecting plug could slay the kid who caused the fault by watering the TV. For an added learning effect the GFCI should have a bypass resistor so it leaks 10mA. That doesn't kill, but it hurts. |

[hazel] - well, try to fix it soon, will you? There are enough environmental problems on this planet without you letting it drain away. |
|

Hazel maybe your TV has taste... |

Brits are not afraid of electricity, the rest of the world seems more scared am I right in asserting that anyone can be an electrician (regardless of qualifications) in the UK were as in the states you have to be registered and qualified? |
|
| |
plus Uk peeps have a full 240 v surging through the place were the rest of you guys have..like .. 9v or something limp wristed like that. |

[Engineer1], I think there is some legislation coming out (or already done), that says qualified Sparkies only for British 'leccy.
DIY repairs also to be outlawed.
Too much mothering...
[Tabs], must have been a common phrase at one time, my Physics teacher used to say the same thing!(or the same teacher ????)
There is a relationship between current, time and likelyhood of fibrillation, as I have linked already in a discussion about bathroom dimmers or something.
I've seen plenty of water leaks, but I've never seen an earth leak....
The Brits call them "residual current circuit breakers RCCB". Changed from ELCB: Don't ask me why. |
