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.
How do you identify the line and load wires on a GFCI?

How do you know which is line and which is load?
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.
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.
Is top or bottom of outlet line or load?

How do you know which wire is hot and which is load?
The easiest way of identifying the line/hot and load wires is to check the colors of the insulation. White and grey wires are neutral; green with yellow stripes, green and copper are ground wires, black can be line/upstream wire, red or black are load/downstream. The white or black are travelers.
What is the load side of a 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.
Is load wire white or black?
So, what color is the load wire? Load wires are mostly black, but red can also be used as a secondary load wire. They are also connected to the switch’s top half, while line wires are connected to the switch’s bottom half.
Can GFCI have two loads?
You can connect two loads to in the same box.
Are load and line wires the same?
Understanding the Terms Line and Load in Electrical Systems. … In the electrical trades, the terms line and load are shorthand words that refer to the wires that deliver power from the source to a device (line), vs. those that carry power onward to other devices further along the circuit (load).
Is line or load the hot wire?
Line is always hot. Load is the wire going from the switch to the device. Load will only be hot if the switch is closed.
Are line and load interchangeable?
On a basic single pole switch the terminals are interchangeable, so as long as you don’t include a neutral wire or swap in a ground wire you can’t really go wrong.
Does line and load matter on a non GFCI outlet?
No. It does not matter if you land the line/load wires top or bottom on non-GFCI/AFCI breakers as long as you land them on the correct side. Brass=hot, silver=neutral, green=ground.
Do normal outlets have line and load?
2 Answers. Normal receptacles don’t have line and load. That is not a thing. That concept is only associated with GFCI and AFCI where the Load provides a protected zone to additional outlets (that are properly wired).
Will GFCI work without load?
Reset using the reset button and see if it trips when you press test button. Yes, if it keeps tripping with no load, it is faulty. Remember that GFCI receptacles can be wired to protect additional receptacles in the circuit so make sure there isn’t something else causing the problem.
How do you know which wire is N and L?
The N is for the neutral side or the white wire, and the L is for the load side, the black wire.
Which wire is hot if both are black?
The black wire is the hot wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the neutral wire, it takes any unused electricity and current and sends it back to the breaker panel.
What happens if you mix up the hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
What happens if you reverse hot and neutral wires?
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.
Can you have 2 GFCI on same line?
Yes, you can have many GFCI outlets on the same circuit The way they vary from a regular outlet is they check for ground faults. many ground faults carry low amounts of current and won’t blow the fuse or trip the circuit breaker, but can kill a person…1/10 of an amp can stop the heart.
How many outlets can 1 GFCI protect?
There’s no limit. A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.
Are GFCI outlets wired differently?
You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit. While it’s common to find GFCI outlets in bathrooms and kitchens, there are GFCI outlet requirements.
