Electricity for Wireless Home Lighting

"Michael Raines, Expert Village. Let's see if we have any juice here. Take our trusty little test light, we're going to turn the switch over. There's two ways of putting wire into a switch. You can put it on these terminals or you can just stick it into the holes in the back. Not all of them work this way. And, when we put our leads on our test light we get nothing. Why? Because, it's a switch. If it was a receptacle we'd have juice. But, is juice really running through this? Yes, it is. But, it's in a different way. Let me show you. If we put it on here and on a ground, our light lights up. That means we do have a hundred and ten volts here. But, it's traveling through the light fixture, through the lights and then grounding out here. Our next step, is to turn off the power. No, you don't work on live wire. I don't care how tough you are. You're going to get a good zap and you're going to know it. No, it won't kill you. It will damage the nerve endings in your fingers. You don't want to get electrocuted very often. I've done it plenty of times, it's not pleasant especially if you get it through both arms. It's not fun. It won't kill you, like I said. But, if you have a weak heart it could cause a stroke or a heart attack. Always turn off the power."
