Third world ingenuity.

You know what happens if you throw the end of a live drop cord into a pool?

Not a god damned thing.

Electricity will flow from one prong to the other. Why do people seem to think some kind of gypsy magic will cause the entire pool to be electrified?

Wat?

Assuming there is not a GFCI and the breaker/fuse doesn't trip, there will definitely be current flowing through the water to ground. There is still potential between the live terminal and earth ground.

There wouldn't be a LOT of current flowing through you and the water, but if you are close enough to the wires, it could be enough to kill you.

True artists. I enjoy watching people who've honed routine tasks to a razor's edge. The only one I question was the long one from India. It looked like a clusterfuck with wasted motion, but what do I know? There might have been a good reason for setting it up that way.

Yeah....it makes me want to dim the lights and grab a glass of wine.

Yeah then they sell the things to the US.

Wet concrete is heavy shit. Those bowls are probably 80-100lbs. All the extra workers lessen the strain of doing this all day long.

The coil for that welder is great!:biggrin:

There wouldn't be a LOT of current flowing through you and the water, but if you are close enough to the wires, it could be enough to kill you.

So you have three terminals (assumably, if using a power tool) right next to each other, immersed in water. Thousands of gallons of water. And you're in it. And we'll assume a metal drain or something is a functional ground (I dunno shit about pools).

You're saying the electricity is going to travel through you...not just through you, but take some kind of long path through you that causes current to travel through your heart...then through however many feet of water, and on to ground at the bottom of the pool...

...rather than just jumping between the terminals that are all less than an inch apart?

It doesn't take the path of least resistance. It takes ALL possible paths back to the source, at the exact same time. The closest, least resistant path will run most of the current, but some will still go through you. It only take ~20mA to paralyze you and ~60mA to kill you.

Again, it depends on the distance from the source, how powerful it is, how long it is generating current, etc.

Drop a 100A, 480V line in a bathtub and I can almost guarantee a BBQ. Drop a 15A, 120v line into an olympic sized swimming pool and you would be fine.

You're right in saying that the 'path of least resistance' is not an exclusive thing. But I think you're applying that thought a bit too liberally.

When there's lighting outside, does everything get struck?

P.S. I'm cool with being wrong. Just applying my own understanding here. I've personally stuck my hand into a glass of water with a drop cord in it to prove a point. But I wasn't grounded via water and plumbing. I could certainly believe that the container size has a large impact. What's in the water is also important; a saltwater pool would have WAY less resistance than fresh water.

Yeah, to ground. If you're on top of the ladder you wont be getting hit with any current. The amount of current going to ground with be small enough that you probably would not get a shock if in the water. The closer you get to that extension cord the more at risk you are though. Best to get someone else to pull it from outside the pool.
