For example, all of the bathroom receptacles throughout a house can be protected by one GFCI receptacle. This is true for the receptacles at a kitchen counter that are required to be GFCI protected. You may only see one GFCI receptacle, but all down-circuit receptacles can be protected if installed properly.Feb 25, 2009
Can you have multiple GFCI outlets on the same circuit?
When you need to wire multiple GFCI outlets such as in a kitchen or bathroom you have a couple of options. To save money, you can put in a single GFCI and then wire additional standard outlets to the "LOAD" output from the single GFCI. This provides the same protection as having a GFCI at each location.
Do I need GFCI on every outlet?

Yes, one GFCI receptacle, just like one GFCI breaker, can protect the entire circuit. To install a GFCI receptacle to protect the entire run, you need to find the first receptacle location on the circuit.
Can you daisy chain GFCI outlets?
With GFCI devices designed for residential installation, there is no need to daisy chain them, as they all are set to trip at around 6mA of leakage current. Daisy chaining GFCIs does not increase protection.
Does power go to line or load on GFCI?
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.
What Is A GFCI Circuit
When a ground fault occurs, the GFCI quickly shuts off the power. The acronym GFCI stands for ground-fault circuit interrupters or GFIs. These are safety devices built into outlets that protect against electrical shock.
How Are GFCI Outlets Reset
Luckily for the homeowner, a GFCI outlet is easy to reset. They have built-in reset buttons that you will need to push back inward to untrip the outlet connection. Let’s take a look at the step-by-step process for doing this safely.
What Does This Cost
You will want to hire a licensed electrician to convert your outlets to GFCI for the protection of the circuit breakers. Also, the national average for 2 GFCI outlets and interrupters will cost $200.
Other Recommended Maintenance
The GFCI outlets that are installed are tied to the circuit breaker box. Double-check that you don’t have a Challenger GFCI circuit breaker box installed while this version of the circuit breaker has been recalled.

Why does my house get hot?
If too much electricity flows through a wire, it will get hot. Sometimes it can get hot enough to start a fire inside the walls of a house. Traditional circuit breakers protect your house from fires by shutting off the flow of electricity to a wire when there is too much demand for electricity. This can happen when too many items are plugged ...

This can happen when too many items are plugged into a circuit. That’s why a power strip can be dangerous if there are too many electric items plugged into it. Circuit breakers do not protect people from electrocution. Their purpose is to protect you from a fire.
Can you get electrocuted from an electrical cord?
For example, if a person is holding a damaged electrical cord from a hair dryer and touches a plumbing fixture, they could be electrocuted. They would certainly get a painful shock.
Brief Overview on How a GFCI Works
The GFCI uses a differential current sensing circuit. A ground fault occurs when the current escape the receptacle across the neutral. A sensor monitors the current flowing through the hot wire and neutral. When a ground fault across the hot and neutral wires occurs, the sensors trip, shutting off power on that circuit to prevent electrical shock.
What Does it mean to Daisy Chain Outlets
Daisy-chaining outlets are merely the practice of wiring several outlets together in series on one circuit. Having multiple outlets on the same circuit is common. The number of outlets used will vary on installing a 15-amp or a 20-amp circuit.
