When someone touches a live current in a house and is electrified, a main fuse is blown and the power is cut I believe as a failsafe.
Why does this happen then?
This will cost ya £65 for the first hour and £40/ hour there after:P
If it’s an old fashioned 60A or bigger fuse then it’s because more than that current level was drawn through it . … quite posibly means the person is dead. More likely that the smaller ring main fuse would blow, either way you can die.
If it’s an earth leakage trip or rcd then it means 30 or 40 mA or so has been detected on the earth or leaking away without returning to neutral and the trip has then fired to save the chaps life, hopefully.
Have a look here: http://en.wikipedia.org/wiki/Residual-current_device
Anyway to wire something so the person doesn’t die? :Whistling:
Yup, run everything off 12v batteries, lol…
ok come on whats happened?
Yep, use RCD’s everywhere, the idea is that they stop you being fried like crispy duck 
No guarantees, or use 12 V at Mole suggested, very safe, even for Mole’s :w00t:
I have few stories about blowing up the house…there was this one time (at band camp) where I thought I’d removed the fuse to an extractor fan, but I hadn’t…I cut through the wire, and BOOM! I had blown up the socket…leaving a black mark, LOL. It wouldn’t have scared me so much except I was standing on one foot, with the other one resting on the edge of my fishtank…LOL
Moral of the story…remove your leg, or the fishtank out of the equation.
There was this other time at work, where I’d unplugged the wrong plug, cut the wire thinking I’d removed it, but I hadn’t…another very loud bang :pinch: and I’d blown the fuse to the entire equipment rack…luckily there was no-one doing a show in the theatre that the rack ran, LOL…the boss was away that day too - just full of luck, LOL! :w00t:
OK! Let me rephrase…Actually let me not… :unsure:
Thanks for the pointers
Afro, seriously, if you’ve not come across RCDs before then leave it to a professional, it’s pretty easy to kill yourself or somebody else with mains power.
If you haven’t got a firm grasp on physics… don’t mess about with electricity, circuits and all that. Get an electrician… a real one 
Racks memory… electricity runs around a circuit. It travels in a direction (depending on diodes etc) and when the circuit is broken (e.g cutting it) then the circuit must complete itself - i.e you. If you are not earthed - you fry. Most houses now have circuit breakers where if a fuse trips, it shuts that part of the board down. You flip the switch and it works again. Pain in the arse when the light bulb blows but at least it stops the rest of your devices blowing. I use the powersurge extension leads for my computer etc coz whilst I have some new wiring when they fitted the kitchen, it’s a 1930’s house and the rest needs rewiring completely.
correct bandit bird except its the other way round, if your not earthed you can sustain massive voltage surges as long as no current flows…however if you are earthed and the current flows through any part of your life support equipment, particularly the heart then your a gonna…
its been a long time since i was at school… i did it as an option for GCSE too … it’s shocking what you forget! :w00t: get it… .shocking… I’ll get my hat

If you’re thinking of wiring your garage or shed to the mains to catch thieving scroats then don’t bother, plod will do you for attempted manslaughter or whatever it is, far worse than the £50 fine the scroat will get.
Afro in vigilante style thieving scum bag shocking shocker
Edited by Afro: Because it made me sound like a thief Eric :rolleyes:
go for it AFRO…you could always say it was by mistake…actually if there are enough warning signs this surely cannot be illegal…if you make it entirely clear that they will be killed if they enter the premises, and they still proceed it has to be their fault…like the lions at the zoo and that plonker that got in with them…wasnt the zoos fault…
But in all honesty the best bet, if your really serious, is to use a cattle fence type system…gives you a heck of a zap but little or no chance of real injury…24 volt systems the best…you would have to make sure it did not electrocute your bike, ie fry the electronic items, mostly the instruments and the Ignition unit…so you may be safest by removing the fuses and even disconnecting the battery…
Dont forget though that she is live when you get up in the morning or you will be getting the zap…ouch.
Ok, I’ll come clean. I was thinking of making a portable tazer like device powered by the mains supply, just as an experiment mind :Whistling: because I always loved working with electrics as a youngster and used to enjoy blowing up the odd TV :Whistling:My device (which would just sit in a display cabinet and never be used) wouldn’t work like a real tazer that fires metal pins attached to the gun by electric cables. No my device would have two foook off great metal rods in the shape of those old Madonna Vogue tits made of a light metal and attached to the 240v mains supply or a generator.The prongs would need to be quite long so that they create a fairly big distance between the shocker and the shockee (this is all hypothetical you understand).Anyway, the fence idea sounds great…Coupled with warning signs, I think it’d make a great detterant although the neighbourhood cat, dog and fox population may be at risk :laugh:To any Police reading this… I’m joking maaaaan But if you get called out and find a would be theif has been electrified at the scene of the crime, please read my disclaimer. **Disclaimer: ** It wasn’t me. I didn’t do it gov. Can I get a witness? If anyone tries any of the above, they are solely responsible for the outcome resulting from the building and use of such a device. Goodluck to you fella, but neither Afro nor LB shall be held responsible. End disclaimer
You mod’ed me!!Only ever happened once before-I feel sullied
My headline was funny - not meant you a thieving bassa!
Give it back!!
No…I am the lauwa!Sorry mate, I can’t remember what you said now anyway…And I didn’t want a witch hunt on me hands…Some parts of the world they tie people like me to the back of pick ups and drive a few times around a very large block
