Electrocution.

[Andy B]

What would happen if you touched the busbar in a ccu with a 60 amp main fuse? I was talking about it to a guy at work today. I said it would probably kill or hospitalise you, he disagreed. I remember seeing a guy touch a live bar years ago when I was an apprentice and he just screamed. So what do you think?

Like truckster says...depends on the fault path, across the chest is obviously the worst scenario but when you get to the levels of amperage where talking about here with enough voltage to push it through somebody`s body then its grim....I am sure most people on here are aware of the u tube clip from india where the poor guy pratting about on the roof of the train carrage gets the full monty from the overhead cable....the man`s on fire.....

Steve, wanna hold my probes? Now lets see, 500 or a 1000?

 

[GLENNSPARK]

Seen that one before....people getting IR tested.....

Yeah, funny aint it?

No it's very irresponsible!!!!

Yea but thats just pass or fail..:hanged: I want values !

 

[GLENNSPARK]

Whoos laughing truckster? One day i will maybe have people working for me and any kind of that stuff going on i will just sack em..seeemples.

Again it doesnt matter what PFC you get at the Origin. The amount of current that passes through depends on voltage and resistance

 

[Jimmy Boy]

It's prospective the greater of PSSC or PEFC in other words the max under negligible impedance, you measure both and the enter the larger value on the cert..Not what you would get through a Human unless of course your Captain Silver...

 

[GLENNSPARK]

Apart from 3 phase steve then you only do a pscc......

 

[Jimmy Boy]

There is always one...

 

[Jimmy Boy]

True well spotted

 

[gibo]

in regard to getting "meggered" it's only a DC shock not AC. makes a whole world of difference

No longer allowed in schools now a days but my school had some fun toys in the physics lab. All high voltage:

• Van De Graaff generator could reach 500,000 volts http://en.wikipedia.org/wiki/Van_de_Graaff_generator
• Whimshurst machine 150,000 volts http://en.wikipedia.org/wiki/Wimshurst_machine
• Tesla coil 80,000 volts http://en.wikipedia.org/wiki/Tesla_coil

I used to enjoy physic even if half the class left looking like the Hair Bear Bunch! Health & safety spoilt the fun for later generations.

im only 24 Tony, and we had a van de graaff. not sure they ramped it upto full spped though.

if your working in live boards invest in a pair of insulated gloves do a lot of testing myself didnt like them at first but soon get used to them and there life savers
