Yes, Ground Fault Circuit Interrupters were specifically designed to provide protection against harmful electrical shocks on circuits without the third wire ground. They cause a circuit breaker to pop if the magnitude of the current is not the same in both the hot and neutral wires (indicating current leakage to something else like a person or water).
However they also happen to make grounded three wire circuits even safer than they already are.

Can you install a GFCI on a 2 wire circuit?
Yes, you install a GFCI on a 2 wire circuit.
Does the neutral wire have a charge in a gfci circuit breaker?
No. Not if the GFCI is wired correctly. The neutral wire should always be cold, or at ground potential.
Why does a newly installed GFCI outlet show open ground on the tester?
Ground wire is loose or disconnected somewhere in that circuit.
What is the green and yellow wire in a plug called?
that's the earth plug and it must be connected, otherwise circuit protection will not operate properly.
How do you wire an outdoor timer into a GFCI outlet?
I assume you are hard wiring it and not plugging it in. The power coming into the GFCI outlet connects to the line side of the GFCI outlet. If you want the outdoor timer protected by the GFCI then connect the wire going to the timer to the load side of the outlet. If you do not want the timer protected then connect it to the line side. On the back of the GFCI if you look closely you will see Line & Load marked on the back.
How do you wire dual switch-plug gfci which has extra wires?
To wire a dual switch-plug GFCI with extra wires, you need to identify the line and load wires. The line wires bring power to the GFCI, while the load wires carry power to additional outlets or devices. Connect the line wires to the line terminals on the GFCI and the load wires to the load terminals. Make sure to follow the wiring diagram provided with the GFCI and use wire connectors to secure the connections.
Can you change a 2 prong plug with a three prong plug if you use a GFCI breaker?
NO - it is not safe to do that. A GFCI breaker is only a secondary safety device and your primary safety still depends on the earth wire in a 3-pin supply.
In USA do you have to connect a ground wire to a GFCI outlet for it to work properly?
Yes, in the USA, GFCI outlets require a ground wire to function properly. The ground wire provides a path for fault currents to flow, which allows the GFCI to detect and respond to ground faults. Connecting the ground wire is crucial for the safety and effectiveness of the GFCI outlet.
Can you install a GFCI on a 2 wire circuit?
Yes, you install a GFCI on a 2 wire circuit.
Does the neutral wire have a charge in a gfci circuit breaker?
No. Not if the GFCI is wired correctly. The neutral wire should always be cold, or at ground potential.
What is a GFCI plug?
Ground fault circuit interrupter. Turns off the the power to the outlet, when the there is a leakage in current. example when you stick your finger in the outlet and the current leaks threw your body
Will GFCI work properly if 240 volt split into one 3 wire 120 volt circuit?
No, a GFCI outlet is designed for use with standard 120-volt circuits. Attempting to use a GFCI outlet with a 240-volt split circuit could cause damage to the outlet, the circuit, and could present a safety hazard. It is not recommended to use a GFCI outlet in this manner.
Why are wires twisted together on a GFCI outlet box?
The ground wires are twisted together and then connected to the GFCI ground. The black and white wires may also be twisted together and then using a jumper wire connected to the GFCI. Hard to say without seeing exactly how it is wired.
How do you convert a two pin plug to a three pin plug?
You can convert a two-pin plug to a three-pin plug by purchasing a plug adapter that has a grounding prong. This adapter will allow you to safely connect your device with a three-pin outlet. It's important to ensure the adapter is properly rated for the voltage and amperage of your device to avoid any safety hazards.
Why does a newly installed GFCI outlet show open ground on the tester?
Ground wire is loose or disconnected somewhere in that circuit.
What is the green and yellow wire in a plug called?
that's the earth plug and it must be connected, otherwise circuit protection will not operate properly.
What does No. 7 cylinder misfire malfunction mean?
It means #7 cylinder is not firing properly. Could be a bad plug or plug wire on that cylinder.
