What does load mean on a switch?

In an AC circuit the supply is the source of power and the load is anything that you are switching on or off to control it like a light fitting, element, motor etc.

Line is the side of the device where the wires from the panel (or other equipment feeding the device) are connected. Load is where any devices that are to be protected by the GFCI device are connected. Most “newer” GFCI devices will not reset if they are not connected probably.

Also, which is load and which is feed? Feed is the mains and Load is the cooker.

One may also ask, what does Earth load and supply mean on a toggle switch?

earth is ground. load goes to what you are trying to power (neons, leds, fogs or w/e) supply is coming from the battery or relay to power everything.

Which wire is load on light switch?

Two or three wires will be attached to the switch: an incoming hot wire, which is black; a return wire, which carries the load to the fixture and may be black, red, or any other color except green; and sometimes a grounding wire, which is green or bare copper.

How do you test line vs load?

You will need a multimeter or voltage tester. Turn off breaker and separate the two pairs. Turn on breaker and test each set for power by reading voltage from hot to neutral. The set with voltage is your source (line), the other is load (no voltage, feeds downstream outlets).

Does it matter which wire goes where on a light switch?

If your switch has a “LINE” marking, the always hot wire goes to this. The other connection will be “LOAD” where the load (ie light fixture) is wired. The load wire may have red electrical tape on it to differentiate.

What happens if you switch hot and load wires?

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 common wire a line or load?

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.

What color is load wire?

The color for the Line wire is usually black and Load wire is usually red, black, or blue (less common).

Which is line and load on outlet?

One set of wires will be the “line,” or power supply. The other set will be the “load,” which carries power to additional outlets on the same circuit. A GFCI outlet, properly installed, will protect all the outlets on the “load” side.

What is the load in a circuit?

An electrical load is an electrical component or portion of a circuit that consumes (active) electric power. This is opposed to a power source, such as a battery or generator, which produces power. In electric power circuits examples of loads are appliances and lights.

Which is feed and load on fused spur?

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 a fused spur?

A fused spur is an electrical supply accessory that incorporates a fuse. This fuse, with a lower rating than the fuse for a ring man, allows an electrical supply using one feed cable to a socket to be taken off a ring main. A variation is a double pole fused spur switch which incorporates an extra isolation feature.

What is load line in electrical?

In graphical analysis of nonlinear electronic circuits, a load line is a line drawn on the characteristic curve, a graph of the current vs. the voltage in a nonlinear device like a diode or transistor. It represents the constraint put on the voltage and current in the nonlinear device by the external circuit.
