Do you connect GFCI to load or line?
When you connect only to the line terminals, the outlet provides GFCI protection only for itself. When you connect to both the line and the load terminals, the outlet protects itself and any additional outlets farther down on the same electrical circuit.
Where are the supply wires attached to a GFCI receptacle?
Black (hot) wire connects to a brass or gold screw on one side. White (neutral) wire connects to a silver screw on the opposite side. Green or copper (ground) wire connects at the bottom of the outlet to a green screw.
Which is load and which is line?
The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.
What happens if you reverse line and load on 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.
What happens if you mix up load and line?
How many wires does a GFCI outlet have?
A cable consists of 2 or 3 wires. LINE cable: Delivers power from the service panel (breaker panel or fuse box) to the GFCI. If there is only one cable entering the electrical box, it is the LINE cable.
Does the black or white wire go to the gold screw?
Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green.
What happens if you switch line and load on GFCI?
How do you identify a load and line wire?
Load Wire – Generally connected to the top half of your switch. If the wire is coming from the top of the switch box, it is likely your load wire. Line Wire – Generally connected to the bottom half of your switch. In some cases, line wires are marked with “line”, “pwr”, or a lightning bolt symbol.
How do you tell which wires are line vs load?
How do you wire a GFCI outlet with black wire?
Make sure the amp rating of your new GFCI outlet matches the amp rating of the wiring and breaker or fuse. Unscrew the terminal screws of the new GFCI outlet until they are difficult to turn. Connect the black Line hot wire to the brass screw marked Line by inserting the wire into the back-wire hole. Tighten the terminal screw.
What are the terminals on a GFCI outlet called?
When it comes to ground-fault circuit-interrupter, or GFCI, outlets, there is always a question as to how to connect the wires. This is because GFCIs have two different sets of terminals: the LINE terminals and the LOAD terminals.
What is Lineline or load with GFCI connection?
Line or Load With GFCI Connection 1 Line Connection. The line connection is the point where you will connect the incoming feeder wire (also called the line), which is fed from the home’s electrical service panel. 2 Load Connection. 3 Ground Connection.
How do you test a GFCI on an unground circuit?
If installing a GFCI on an ungrounded circuit, refer to the manufacturer’s instructions. Place the red probe of the voltage tester to each black wire until the tester lights up. This is the black wire that will connect to the Line brass screw terminal.
