Since testers establish a test circuit between hot and equipment ground, if the receptacle into which the tester is plugged is wired with reverse polarity, there will not be a voltage across the tester and test current will not flow. The GFCI
Residual-current device
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
What happens if you don’t have power on the GFCI?
What happens is that you won’t be able to Reset it to have it work. You need power on the Line side to have the Reset button work. Without that power, nothing is going to happen. I learned this when I couldn’t get a GFCI to reset. A wiser person asked if I had power on the Line side. “Nope” I said. “ The breaker is off’.
Where do the wires go on a non GFCI outlet?
In GFCI outlets, the line wires connect to the the top screws and the load wires connect to the bottom screws. Does this convention apply to non-GFCI outlets as well? So here’s the thing about outlets….There is no official upside for an outlet…the ground hole can be top bottom left or right.
Where does the light go when the GFCI goes off?
If the light goes off it is downstream of the GFCI. If the light stays As you stated you knicked with paint paint a standard tamper resistant receptacle, as shown in the photo. (BTW - thanks for your great description and very helpful photo.
What happens if an outlet is wired backwards?
What happens if an outlet is wired backwards? You have a outlet with three wires. What does backwards mean? If you mean the reversal of hot and neutral, everything will probably continue to work without a clue of trouble.
Can a GFCI outlet be wired backwards?
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. The older ones would still work and provide GFCI protection for load connected devices but the receptacle itself would NOT have GFCI protection.
What happens when you reverse line and load on a GFCI?

But it won't reset. With older gfcis. The outlet will trip but the outlet remains.
What should happen if you reverse GFCI receptacle connections?
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.
How do you tell if a GFCI is wired correctly?
Using a GFCI Tester The tester can tell you whether the outlet is wired correctly and can also identify several wiring problems, including open ground, reversed polarity, an open hot or neutral, and a reversed hot and ground. The tester also has a test button that trips the GFCI to check the safety function.
Can Reverse polarity cause a fire?
Yes, if you accidentally reverse the polarity on an electrical outlet, the device you plug in to the receptacle isn't safe and could cause a short circuit, shock, or fire.
What happens if an electrical outlet is wired backwards?
One common issue with electrical outlets is reverse polarity, also known as "hot-neutral reversed." In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
Will an outlet work if wired wrong?
This makes things like lamps and many appliances more safe to operate. But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward.
Can reverse polarity damage electronics?
When plugged into an outlet wired incorrectly, reverse polarity can easily damage your electronics. If your electronics do not have any mechanism to protect against reverse polarity built into the circuitry, it is only a matter of time before they are damaged.
Which side of GFCI is hot?
The line connection is used for all GFCI outlet installations. The circuit's hot wire (typically colored black or red) connects to the black or brass-colored screw terminal marked LINE. The white neutral wire connects to the silver-colored screw terminal marked LINE.
How do you fix a GFCI that won't reset?
If you test and reset your GFCI outlet, but it still won't stay reset, a good idea is to check the breaker box to make sure the circuit breaker hasn't tripped. Try resetting the outlet. Once you reset the outlet and it still doesn't reset, moisture buildup in the wiring or outlet may be the culprit.
Why does my GFCI keep tripping?
If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.
What does it mean if a GFCI wont reset?
A GFCI or GFI outlet may not reset because there's a ground fault occurring at a regular outlet that's not working, or somewhere else downstream of the GFI. Also, if no power is reaching the GFI, it may not reset. The component will not function properly if power does not reach its electrical box.
What do you do when hot and neutral are reversed?

What's the difference between line and load on a GFCI?
There are two types of wires attached to the receptacle. The “line” wires are the incoming power from the breaker box and the “load” wires are the outgoing power that travels down the circuit to the next outlet.
Why can't I reset my GFCI outlet?
Push Reset Button If the GFCI won't reset or the button doesn't pop out when you press the "test" button, there may be no power to the GFCI or you may have a bad GFCI. Pro tip: If the "reset" button trips again every time you press it, there may be a dangerous current leak somewhere on the circuit.
Can GFCI share a neutral?
Yes. GFCI receptacles work fine supplied by a multi-wire circuit. GFCI circuit breakers have a separate terminal for the neutral wire which must be run with the hot wire.
What happens when you reverse a GFCI?
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. If the load and line wiring gets messed up, a ground fault (radio in the tub) won't trip the GFCI. Click to see full answer.
Can you replace an outlet with a GFCI?
You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit. Beside this, what happens if an outlet is wired wrong? If your outlet's polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be.

I don't know if they all work the same way, but the ones I have looked at are pretty simple. They start in the tripped state. The reset button is no longer a simple mechanical device; it is interlocked such that the device cannot be reset unless there is power on the line side.

Humans are very resourceful. If there is a way to break something, a human can discover how. ^_^
