Measuring your equipment’s wattage is a good way of knowing if you are overloading your UPS, or if you have too many things plugged in to the same circuit. This article will show you how you can test wattage of your equipment using a multi meter and a few wires...

There is a little conflict between what you say. Did you knew that dangerous currents are measured in tens of milliamps? Resistance of person is limitting current, so current in machine doesn't mean anything. Current depends of voltage and resistance so big voltage is the dangerous thing in these measurements.

It's possible to do something dangeraus and still know what you're doing.

Look at those crazy stunt people like jackass. It's unsafe, but they know what they are doing so they (usually) don't get hurt.

As for the accurcy, I sort of realized that afterwards, when I did more research, but this method will still give you at least an idea of wattage. If you can afford the fancy stuff that does it right good for you, but especially here in Canada it's not obvious to get the fancy stuff, sometimes it's too expensive, sometimes you can't even get it period.

Yeah I discovered that after, so I had added it at the end that it may not be very accurate. I'm not sure if mine is RMS or not, but I doubt it since I only paid about $100 for it. Later on I'll try to figure out a better way (low cost) to measure true RMS with any meter. (maybe plug the results in some formula or something but I doubt it's that easy)

1.24 is pretty high for 240 bolts, do you have lot of high end stuff in it? Mine ran at about 1.2 (inacurate though) at 120 volts.

I've been zapped many ways and I can easly say from experience the most fatal is the heart thing like mentioned. By nature some people are forced to hold on tight to whatever they are being zapped by. Thankfully for me I'm the oposite. I got zapped with who knows how many amps from arm to arm, and I felt it for like an hour. It was only 120 volts. The zap might of lasted about a milisecond or 2 but enough to make me tempoarly black out and "wake up" 5 feet behind me. I was laughing though but it would of been fatal. Stupid guy put the ground wire in the live and I was holding the "grounded" device in one arm and went to unplug it with the other. Zap!

lol. I knew this article would get lot of safety concerns.

If you use common sense, dangeraus situations can be made safe.
