Speaking as someone who has some training in electrical safety I'll say this: ensure anything you buy is properly supported by standards and marked accordingly. Don't ever pick up or unplug anything with wet hands. Lastly, understand that electricity is very unforgiving, just because something looks 'dead' (meaning a wire(s)/cable(s)) doesn't mean it is, always test first.

LOL.... My grandpa was an electrician at US Steel (been dead since 1985), and he used to check 220 to see if it was live by licking his thumb and touching the wires.... LOL

And no, he didn't die of electrocution! :wink:

As I pointed out in an earlier post before the safety culture that was desperately needed in the electrical industry, part of the practice of for testing for live on 3 phase 400VAC was to use the back of your hand. It was actually written in the standards. I have little doubt there are still some older guys doing this.

I've worked on live equipment up to 3 phase 600VAC with DC bus voltage of around 870VDC if my memory serves me, it's been a few years.

I've been zapped by 120VAC (a couple of times) and 220VAC (once and that was enough) and I know of people who've survived being zapped by 480VAC. It all comes down to the conditions and the situation. An electrician has special shoes that isolate them from the floor so you're not grounded and as long as you're not touching any other metal or conductive physically with other parts of your body you're what's considered 'neutral' and should survive a quick zap. We often talk about the one handed rule when going anywhere near live equipment while testing. In a lot of industries these days you're not allowed to go anywhere near anything that is live due to insurance and safety standards. The only thing you can be near 'live' is considered safe voltage, anything below 50V. Most companies don't like you going anywhere near 220VAC live. You would be surprised how easily 120VAC can drop you to the floor under the right conditions. Part of my safety training, I've had lots, I had to watch a couple of unpleasant videos and see some unpleasant photos. One of the videos was simply about the dangers in the home with 120VAC. Thankfully there are new standards for homes but there are lots of older homes not up to the new standards and are really quite dangerous.

smaller user base = less chance for disasters probably

Electronical lesson one:

The formula for the amount of power lost per second = P = I^2 * R*t
When the I (current) is very low, the amount of power that is lost because of heat will be less. Because AC is easier to convert (a lower current means a higher voltage) to a higher voltage, AC is used the most and converted back when needed in a device that needs DC. In that way you conserve as much power as possible.

The amount of electronical educated people on WPC is too **** low!
