Or as much as a couple hundred thousand under the right conditions. This is a bit more than it takes to kill . Most people don't realize how little current it takes to kill . Take a 100 watt light bulb for example, at 120 volts it draws about .8 amps or 800 milliamps . If you get as little as 50 milliamps flowing across your chest which can happen simply by touching a live conductor with your right hand for example and your left hand is touching something grounded it can stop your heart or throw it out of rhythm. So yes you could die putting up your Christmas lights . Happy New Year ........maybe , lol.
