How to Be Safe With Projects That Involve Mains AC
Intro: How to Be Safe With Projects That Involve Mains AC
If you are a beginner electronics hobbyist, you may encounter some projects that require you to plug right into the wall. This is a potentially dangerous thing if you don't know what you are doing. There is 120 volts in the standard US outlet and 240 volts in the UK (correct me if I'm wrong) this voltage can kill or give a nasty shock depending on the path of the current. In this Instructable I will give you some general rules to follow in order to safely work with Mains AC

With many devices a couple of volts one way or the other doesn't matter much. I did rewire my pool pump because whoever did it ran too long a wire of too thin a gauge to it. What was there was 14 gauge SG stranded cable, I replaced it with solid 12 gauge UF. Induction motors can be sensitive to brown line conditions. They can run hotter, and have a harder time starting if voltage is low to them. I had a 4 volt voltage drop to my motor before I ran a new wire to it.
I mean it worked with the old wire, but it was kind of marginal. I felt better for changing it. Especially being as the motor is on a timer and I'm not always home.
