Does a GFCI have to be the first outlet in a circuit?
Yes, a single GFCI (Ground Fault Circuit Interrupter) receptacle outlet will protect everything on the circuit, but ONLY if it is placed at the first outlet location. If it is installed anywhere else, then it will protect everything downstream, but not any outlets between the GFCI and the panel.
Can you wire a GFCI at the end of a circuit?
If your objective is to protect just one outlet, for instance, an outlet in the kitchen, and that outlet happens to be at the end of the circuit, you can install a GFCI on an outlet at the end of the circuit. Yes, it makes more sense to place it at the start because that allows you to defend all the outlets downstream.
Can a GFCI be in the middle of a circuit?
What is this? If your outlet is in the middle of your circuit (meaning, other outlets or switches are wired through it), you may have two black wires coming out of the wall. Ensure the ends are stripped and twist together, using a wire nut, with the black GFCI wire.
Does 1 GFCI protect the whole circuit?
The GFCI circuit breaker controls an entire circuit, and is installed as a replacement for a circuit breaker on your home's main circuit board. Rather than install multiple GFCI outlets, one GFCI circuit breaker can protect the entire circuit.
Can you have 2 GFCI outlets on the same line?
Yes, you can daisy chain GFCI outlets together, but it's unnecessary and provides no added safety. There's nothing that says you can't install multiple GFCIs on the same circuit. However, there is no additional safety gained by doing so.

It does not sense solid short circuits between the “hot” conductor and the grounded “neutral” conductor. The branch circuit fuse or circuit breaker provides this protection.
Why is there no current in a coil?
No current is induced in the coil because both wires are carrying the same current. The ground fault circuit interrupter does not trip the circuit off. Figure 1a – No current is induced in the coil because both wires are carrying the same current.
What is a branch circuit breaker?
The branch circuit fuse or circuit breaker provides this protection. It does not sense solid short circuits between two “hot” conductors. The branch circuit fuse or circuit breaker provides this protection. It does not sense and protect against the damaging effects of arcing faults, such as would occur with frayed extension cords.
Does a GFCI have to be unbalanced?
Thus, there is no unbalance of current for the GFCI to sense and trip. It does not limit the magnitude of ground fault current. It does limit the length of time that a ground fault will flow. In other words, you will still receive a severe shock during the time it takes the GFCI device to trip “off.”. See Figure 3.
How does a GFCI work?
The GFCI works by measuring the current leaving the hot side of the power source and comparing it to the current returning to the neutral side. If they are not equal, this means that some of the current is flowing along an unintended path possibly through water or through a person.
