Here we go again. Where were you when I had this problem. I was selling a house and the inspector caught this problem in the bedroom plug. I tried to fix it but without any luck. I called an electrician and he had to trace the problem all the way to the bathroom switch. So the problem could be different than the plug itself. The house was fairly new and I wondered how so many inspectors missed this problem starting with state inspection. Well explained and thank you for sharing

As someone working in residential housing construction as an electrician, it's a horror show. The inspector does not inspect everything. Sometimes my coworkers run out of weather resistant gfi plugs, so they use the normal ones in an effort to fool the inspector, knowing he won't check. Many don't even understand basics and don't utilize critical thinking because they take a completely procedural approach. They don't need to know how everything works they just need to know how to put it together. Everyone comes under the impression that the world has rules that must be followed, but honestly, it seems the are a lot of people in society who just.. don't care. Not out of malice, but pure apathy. Almost reads like exhaustion. And yes, I'm trying desperately to get a new job, it's just really hard.

Good explanation! I think you covered two of the three big topics: outlets, light fixtures, but also switches. If your light fixture is wired correctly, but your switch is wired incorrectly, I think you end up with the same problem. In particular, many people will do fixture work by flipping the switch off because they don't want to deal with the breaker, but if the switch is wired backward, you can still have hot waiting for a path to ground all the way at your work.

@docferringer 2 жыл бұрын

I came here to say this. Having a lightbulb with its threads exposed is a good example of something an everyday homeowner (or their kid) might do and not consider it in any way dangerous. But a DIYer trying to change a light fixture with just the switch turned off and not the breaker? That's a nice, educational shock for DIY electrical work. It doesn't matter if you know what you are doing, get a voltage tester or a mulltimeter to check for voltage before you touch ANYTHING. If I don't want to play the breaker guessing game then I will tape the light switch in the off position. That way all of the people I tell not to touch the switch will have a second warning before I come down the ladder and dole out some verbal education.

The ceiling fixtures are most dangerous because you are usually on a chair or ladder changing a bulb. Getting zapped may not injure you, but falling off a chair could have very bad outcomes. Old school metal recessed cans are grounded. Even brushing the springs or clips that hold the baffle in place have given me a zap before I finished screwing the bulb in. I'm guessing that was the easiest return when the threads were live neutral was switched off.

The Edison screw (which is what you would consider a standard light socket) was developed quite a while ago. The polarized plugs and sockets used today were an attempt to make the Edison screw safer. The intent is for the large easily touched screw portion to be at neutral, while the hot portion is the little contact at the center of the bottom on the socket. (The easy to touch part = neutral, while the hard to touch spot = hot). Frankly, if the Edison screw were to be developed today, it would have been immediately rejected due to safety issues. But given how long ago it was developed, and how many of them have been installed over the years, it's a legacy device that's virtually impossible to get rid of.

I had a reverse light bulb socket, I actually found it when I installed an led. I have almost switched all my bulbs to LED, but the fixture in question I noticed a very soft glow when the switch was off, it was such a low amount of output that almost all other light sources had to be off, so I put that led in another fixture and did not have the same symptom. I actually discovered it was backwards at the switch, which meant hot was always hot, but still hopefully that’s useful information to someone

@okaro6595 2 жыл бұрын

That glow is caused by capacitance between the wires. You can get it even without a reverse switch but that does increase chance of getting it. Better bulbs have methods to prevent that. U just shows how sensitive the bulbs are. A common method of wiring a switch is to draw one cable from a junction box into the switch and use the neutral as the return. The two wires close together create a capacitor that passes some AC.

Good advice. I have used potatoes for unscrewing broken light bulbs. Including for a 150 watt high pressure sodium bulb in a yardlight that was busted from being hit with a football during a party. I was depending on the photocell not to kick on, super dangerous because of the high voltage ignitor, (2500 to 4000 volts) found in all high pressure sodium and smaller (150 watt and under) and many newer metal halide fixtures (pulse start metal halide)
