If there is no ground available, the ground wire should be connected to a metal water pipe or a grounding rod to provide a safe path for electrical currents.
If there is no ground available, the ground wire should be connected to a metal water pipe or a metal rod driven into the ground to provide a safe path for electrical currents.
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
With limited information available as to the type of equipment that is to be grounded it is always safe to place the ground wire on the equipments frame. This will not be grounding but bonding which will keep all equipment within the electrical circuit on the same potential which should be zero.
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
No, the hot wire should not be connected to the ground wire in an electrical circuit.
A jumper wire should use to bridge electrical ground across?
The bare wire from the old 3-wire stove should be connected to the grounding terminal in the panel. The neutral and ground should not be bonded together at the stove. If the stove requires a 4-wire connection, it's best to run a new 4-wire circuit to meet current electrical codes for safety.
The green wire from the light fixture should be attached to the ground wire in the electrical box to provide grounding for safety purposes. This helps prevent electrical shocks and protects against electrical malfunctions.
No. Green should always signify the ground wire.
There should be a black ground wire in the Chevy Celebrity radio wiring harness. If for whatever reason that is not available then simply hook a wire from the metal shell of the radio to a convenient point on the dashboard near the radio. I would use a convenient bolt or screw if at all possible.
If the wiring system into which you are installing an outlet has no ground available, use an ungrounded outlet. In an ungrounded system, an outlet with a ground contact would allow the outlet user to mistakenly, and perhaps dangerously, assume that a ground was present. A suitable ground may be available as a ground wire accompanying the hot and neutral wires in the cable, or a ground may be available via conductive conduit and a metal outlet box. In any case, use a tester to confirm the integrity of the assumed ground. A voltage test from the hot wire to the ground should show the same voltage as between hot and neutral (the black and white wires respectively). If you are replacing an ungrounded outlet, you need not assume there is no ground present. You may find, in the box, ground wires that were not connected to the outlet. You may come across grounded outlets that have no ground wire attached because they rely on grounding via the mounting screws through the outlet ears to the metal box. This is a less reliable grounding method. It is better to buy a ground-wire "pigtail," fasten the wire directly to a hole in the metal box with the supplied screw, and attach the other end of the ground wire to the outlet via the outlet's ground screw.
The ground wire should come from the ground rod and to the main electrical panel grounding terminal.
