The newer GFI receps were changed so they will not work if they are wired backwards. Older ones would still work but would not GFI protect the load conductors. Its been a while since I've encounter an older style backwired, and I somewhat agree with jwjrw except to add, and I think this is correct, on the older units, the test button will actuate but the receptacle will not turn off.
I recall asking a mfg rep about this and he said that was why the instructions advised to test with a load plugged in. Location Torrington, CT. Click to expand These are the new devices. Does the backward wiring cause damage to the circuit board, so that if the devices was rewired correctly it would not function properly? If your outlet's polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be.
Can a start capacitor be wired backwards? Watch out: Reversed polarity on an electrical outlet is dangerous. A ground fault circuit interrupter GFCI outlet is a special type of circuit breaker that can automatically shut off power directly at the outlet when it detects an electrical fault. Here's what happens when somebody wires a GFCI receptacle with the load and line wires reversed: The GFCI will work, in the sense that you can plug in a hair dryer and the hair dryer will blow hot air.
The other cable connects to the LOAD terminals to bring power downstream to additional outlets and other devices on the circuit. They are correctly wired in parallel - if they were in series, you wouldn't get the correct voltage at the other outlets when there is any type of load present.
Connect the feed cable wires to line and the others to load on the GFCI. Bruce, the GFCI itself may be bad and need to be replaced. Notice: Installing additional GFCI outlet wiring should be done according to local and national electrical codes with a permit and be inspected. The white neutral wire connects to the silver-colored screw terminal marked LINE. The line connection is used for all GFCI outlet installations.
If not, the GFCI is not working or has not been correctly installed. This may not sound like a terrible thing, but it is. The easiest way to upgrade an ungrounded V receptacle to get ground protection is to replace it with a GFCI outlet. The pen will glow red when the wire is hot.
It does not need any reference to neutral or ground to do this. Push the reset button on the GFCI outlet. If you accidentally reverse these wires the device you plug in to the receptacle may "work" but it is unsafe and risks a short circuit, shock, or fire. Can you wire a GFCI wrong? If the appliances and devices you want to operate do not use a neutral, your GFCI will work without a neutral.
Neutral is the white wire that leads back to the panel, completing the circuit. A GFCI with an open neutral is unlikely to work. An open neutral is dangerous because the current is still flowing which means that, depending on what you touch, the outlet can still shock you. You can try inspecting the GFCI but you may not locate the cause of the open neutral.
In a receptacle, connect the white wire to the silver terminal with the white mark on top. A GFCI needs hot and neutral wires to work. The hot wire sends the current out. The hot wire is normally black or red. You can use a tester to identify it. The hot wire connects to the line terminal. You have to strip the hot wire to connect it to the line terminal.
You should switch the power supply off before you proceed. Otherwise, the hot wire will electrocute you. The hot wire is black or red. Strip the wire and connect it to the hot terminal. It is brass-colored. You can wire a GFCI with two hot wires by slicing the hot wires and tying them in a pigtail. Attach the pigtail to the hot terminal. You could start a fire. Anyhow, the big problem with the electrical upgrade at my friend's house was that the handy homeowner had wired all the GFCIs ass-backwards.
This would've left everybody in the house vulnerable to radio-wielding killers. Y'see, GFCI receptacles come with in-holes and out-holes, not unlike the amplifier on your stereo system. There's the input side, labeled "line," and there's the output side, labeled "load. However, as you might suspect, a whole lot of people don't read the instructions.
They just start stripping wires and plugging 'em in randomly, until the lamp plugged into the receptacle comes on. With the use of lax wiring standards, the functioning lamp is the signal that the wiring job is done and that it's time to bust open a case of beer. Once a GFCI is wired up, some safety-minded folks might go so far as to push in the little "test monthly" button.
When you push that button, the "reset" button should pop out, and it usually does. Anybody with decent common sense would figure that if the "reset" button pops out, the receptacle is dead. After all, if it weren't dead, why would you need to push the "reset" button back in?
