Title: Bloomin Eletrics
Post by: Poison_UK on April 16, 2006, 17:24:49 PM
Nothing half wakes you up than a 12v shock of a terminal in the car :D

Was stripping out wireing for a new light switch controller and well a screwdriver got caught up with my fingers and some wires and Zappp!

Saying I didnt get any sleep at all last night and im running on semi-caffine ermm it woke me up rather nicely :D

Its the amps that kill.

<<< has had 11kV through him. :D

Oh and there is enough ampage in that battery to kill you :) so BE CAREFUL!!!

300Amps on start is the norm. IIRC.

i have bridged the pins on a alternator when taking off an oil filter before that wasnt fun, and i have had afew 240v mains belts before, wakes you up to say the least.

tbh Ive only ever had a shock from a ciggaret lighter in a car.... and I do everything but stick the cables in my mouth :o

oftern wondered why sometimes it shocks, and others not :dunno:

I guessed it could be something to do with the distance between the 2 points of contact on your skin for the +ve and -ve, but then theres plenty of times ive had big hefty cables in the same hand.

anyone know ?

the resistance is really high on your body.. just dont sweat cos that reduces it massivly and will allow you to be shocked easily

Just disconnect the +ve terminal before you do any work!! Just remember your stereo codes!!

the resistance of your body is usually pretty high, as a rule of thumb 12v wont usually shock you...

u *usually* need 28v + to get a shock, but having wet hands or something will reduce the resistance of your body a lot.

GIRL ! (and thats putting it politly :p )

start working with a nice few 3 phase cabl;es as thick as your arm at 415v live and you soon get the hang of it ;)

That is what you can get for a whole hour, u could get 480 amp for 15 minitues from that battery

aha.

I have never been belted by a battery befor.
Even licking your fingers and touching both terminals dont do anythin.

I always get shocked by the ht leads though, and the rev counter feed.

ht leeds run at a much higher voltage, but tiny amps, I dont kow why buy I have 11,000 volts in my head for some reason ? sounds a bit too much to me tho :o

thats what the coil does :)

11000v was the HT lead voltage on a B&W TV, 25000V is the colour HT voltage from what iv read

Ive only been "shocked" by a resistance tester, or whatever it was.  It was in college, electrical lecturer wanted to give us an idea of what it felt like for those who hadnt been shocked before.

I quite enjoyed it oddly tbh, the whole muscle spasm thing.  "Again, Again" :D

thats hardly a real shock you were expecting it... its when your not that it really gets you going lol

500v those resistance testers. they used to do that in my college untill someone nearly died of a heart attack.

Ive had several arguments with Mr 240volts and it hasnt killed me so far, saw interesting stars twice though when it was dark...

You on about a megger tester?

Modern ones charge capacitors up and discharge just using batteries. Ive been shocked by a megger a few times, used to have old ones that you had to crank up... used to play catch with them, or rather crank it up, then throw it at someone. Natural instinct was to catch it :D lol! :D

Ive had 11kV through me on a similar device, used it in EMC testing to test earthing of equipment. Was during a work experience the engineer who was teaching me for a bit gave me a jolt by surprise. made my arm and right side of my body spasm, kept having twitches for about 5 mins afterwards.

its 26,500v on a cathode ray tube in a TV I think.

Edit: The worst thing Ive been shocked with was a soldering iron. The heat combined with the spasms caused by being in contact with the mains! made for an interesting time.

OW! it tripped the leccy out in the electronics lab thank god so I released it as soon as I got shocked, but bugger me that hurt.
