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.
How do you tell 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.
Is line or load the hot wire?
Line is the wire that goes from a source to a switch. It's upstream of the switched device. Line is very hot. The wire from the switch to the device is called load.
Which is line and load on outlet?
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.
Which is load wire?
Load Wire: This is the wire that connects your switch to your light bulb or other “load” (ie: a fan or other appliance). It is also usually black. The Brilliant Control can automatically detect which wire is “Line” and which is “Load”, so they are interchangeable when installing in a single-pole configuration.

What happens if you mix up line and load on GFCI?
If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.
Which is supply and which is load?
The supply goes to the power source. Load goes to whatever you turn on and off.
Is the black wire load or line?
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.
Which wire is hot when both are same color?
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
Which wire is hot if both are black?
Here's a rundown of electrical wires: 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 wire a light switch backwards?
But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
Which side of outlet is black wire?
White (neutral) goes on the side allocated for the larger prong. Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green. 3) Strip wires, about an inch.
What is the load in a circuit?
An electrical load is simply any component of a circuit that consumes power or energy. In a household setting, the most obvious examples of electrical loads include light bulbs and appliances.
What is load and feed?
The feed is the cable from your fuse board, supplying the power to the isolator switch. The load is the cable supplying the appliance once you have switched the isolator into the on position.
What is the load on a socket?
Plug load is the energy used by products that are powered by means of an ordinary AC plug (e.g., 100, 115, or 230 V).
Can line and load be switched?
You could mix up load and line on a GFCI switch and all your daisy-chained outlets would still work, but you wouldn't get the protection from electrocution.
Which side of GFCI is hot?
The line connection is used for all GFCI outlet installations. The circuit's hot wire (typically colored black or red) connects to the black or brass-colored screw terminal marked LINE. The white neutral wire connects to the silver-colored screw terminal marked LINE.
How do you tell if a GFCI is wired correctly?
Using a GFCI Tester
The tester can tell you whether the outlet is wired correctly and can also identify several wiring problems, including open ground, reversed polarity, an open hot or neutral, and a reversed hot and ground. The tester also has a test button that trips the GFCI to check the safety function.
Is line a load or common?
Remember that one side of the common on the three way is the line side and the other common is the load side or switch leg. The two wires that connect between the 3-ways switches are carriers.
Can you cross line and load in a disconnect?
Thus, your line and load cannot cross in your main service disconnect. Think about the number of cheap pull out discos that fly in the face of this, then remember they are not service equipment.
