Questions about: grounding - страница 3

Electric motors convert electrical energy into mechanical energy using conductors and magnetic fields. Motors require thermal protection to prevent damage due to.
The grounding conductor in an electrical system provides a safe path for fault currents to travel along. It's there to prevent electrocution. Let's say we have a toaster
If the conduit is metalic, and at least size 3/4", and at least 8 ft. long. Then you should be able to use it as the grounding electrode for the antenna
Here's my best guess at the wiring based on the photo. Looks like you've got one hot/neutral coming into the box from the panel (or another switch/outlet), and you've got 2 hot/neutrals going out of the box to other switches/outlets. Since these are
We're changing the extremely old fixtures in our hallway with some sleek modern LED lighting. Upon removing the fixture I discovered three sets of twisted wires - double white, black-red (the fixture used it for the black) and a black-white pair that
The rod must be at least 8 feet in the ground, and should be below or flush with the ground level. If the electrode is above the ground, it has to be protected from physical damage. So if the rod is 8 feet in the ground, you'll simply have to protect
Neutral and ground should be bonded only in your main service panel. Sounds like, in your case, that's the one attached to your meter. Secondary panels should have separate neutral and ground bus bars
Generally, adding a ground wire is always better for electronic equipment. It helps surge suppressors do their job by providing a ground reference. It provides real chassis grounding which among other things gives a solid route for static electricity
I was changing a light bulb in a ceiling light fixture. I unscrewed the nut and removed the glass cover. When I was replacing the bulb I noticed that there was a copper wire loosely coiled around the center rod (threaded at the bottom
