In the context of electrical systems, the term line feed is not commonly used. However, the terms line and load are often used to refer to electrical wires. Line refers to the wires that feed electricity from the source to a device, while load refers to the wires that carry power onwards to other devices along the circuit. In computer science and printing, line feed refers to advancing paper in a printer by one line or moving a cursor forward one line on a computer screen.

Line wires are always hot and carry the electrical current
In electrical wiring, the terms "line" and "load" refer to the electrical wires that deliver power from the source to a device (line) and those that carry power onwards to other devices further along the circuit (load). Line wires are always "hot", meaning they carry an electrical current and act as the "supply lines" of electrical power. They are generally black, but this is not always the case, and colour is not a reliable indicator of wire type.
In the context of a single device and electrical box, the line is the wire that delivers power from the source to the device, while the load is the wire that carries power from the first device to the second device downstream. For example, in a light switch, the line wire carries power to the switch, and the load wire carries power from the switch to the light. If the switch is cut off, the power to the light is also cut off.
In a series of outlets wired in sequence, the load wire feeds electricity from the first outlet to the remaining boxes on the same line. The load wire can be thought of as a "continuation wire" that carries electricity from a terminal point to the point of use. The line wire, on the other hand, is always connected to the incoming source power.
When wiring low-voltage circuits, such as those for doorbells or landscape lights, the line refers to the parts of the circuit that are at full household voltage (usually 120 volts). This distinguishes it from the low-voltage wiring and devices used after the voltage is reduced by a transformer. The load, in this context, refers to the electrical demand or power draw that a device or appliance places on a circuit.

Load wires carry electricity to the next device on the chain
In the electrical trades, the terms "line" and "load" are shorthand words that refer to the electrical wires that deliver power from the source to a device (line), and those that carry power onward to other devices further along the circuit (load). A number of other more conversational terms are also used to describe the same thing, such as incoming vs. outgoing wires or upstream vs. downstream.
The line is the wire running from the service panel to the device, while the load is the wire running from the first device to the next. In other words, the line carries power from the service panel to the device, while the load carries the power from the device to the next. Another way to look at the line and load is that the line is the power supply source, while the load is the destination point of an electrical circuit. The line wires carry electricity, and the load wires move it along.
Load wires are the wires that carry electricity from the line wires to the other electrical components in a system. They are broader in definition and continue to carry electricity from a terminal point to the point of use. In light switches, for example, the line wire carries the power to the switch, and the load wire carries the power from the switch to the light. When the switch is cut off, the power is cut to the light. If you have a series of outlets wired in sequence, the load wire is the wire that feeds electricity from the first outlet to the remaining boxes on the same line.
Load wires are generally red, black, or sometimes blue. They are usually positioned near the top of outlets and switches. It's important to note that the neutral wire acts as the return path for the current being supplied on the line wires.

Line and load have special meanings when wiring ground-fault circuit-interrupter (GFCI) outlets
In electrical wiring, the terms "line" and "load" are shorthand words referring to the electrical wires that deliver power from the source to a device (line) and those that carry power onwards to other devices further along the circuit (load). In the context of wiring ground-fault circuit interrupter (GFCI) outlets, the line and load connections refer to the wires that deliver power from the electrical source.
GFCIs are safety devices designed to prevent electrical accidents, shocks, and burns by shutting off electrical power when they detect ground faults. They are commonly used in kitchens, bathrooms, garages, and areas where electrical devices may come into contact with water. GFCI outlets have two pairs of screw terminals for connecting wires: one pair is marked "LINE", and the other is marked "LOAD". The line terminals are not covered and are easy to identify, while the load terminals are typically covered with a yellow strip of tape.
When wiring a GFCI outlet, the line connection is where the incoming feeder wire, or line, is connected. This wire is fed from the home's electrical service panel. The line wire carries power from the source to the GFCI device. The load connection, on the other hand, brings power downstream to additional outlets and other devices on the circuit. It moves the power from the GFCI to the next device on the chain.
Connecting only to the line terminals provides GFCI protection for the outlet itself, while connecting to both the line and load terminals extends protection to any additional outlets farther down on the same electrical circuit. This setup reduces costs as it eliminates the need to purchase a separate GFCI for each outlet. However, a downside is that if there is a ground-fault condition with any of the added outlets, the GFCI outlet will trip, which may be inconvenient if it is located at a distance or in another room.

Feeder wires can feed branch circuits by having bigger current flows
In electrical systems, the terms "line" and "load" are used to refer to the electrical wires that deliver power from the source to a device (line) and those that carry power to other devices further along the circuit (load). Line wires are always "hot", meaning they carry an electrical current and are the "supply lines" of electrical power. They are usually black, but this is not always the case. Load wires, on the other hand, are broader in definition and carry electricity from a terminal point to the point of use. They are usually white, but can also be red or blue.
Now, feeder wires are distinct from both service and branch circuit conductors. They deliver electricity within a house, taking over after the service entrance that brings power from the utility pole and supplying power to the branch circuits. Feeder wires can, therefore, feed branch circuits by accommodating larger current flows than those running a branch circuit. This is because feeder conductors are generally larger than branch circuit conductors.
The National Electrical Code (NEC) has specific requirements for feeder conductors, including installation, conductor sizing, and overcurrent protection. Feeder circuits must include an equipment grounding conductor (EGC) that allows branch-circuit EGCs to connect to it. Feeder conductors are also required to have a minimum ampacity based on the load they serve.
It is important to distinguish between feeder and branch circuits when installing or repairing electrical systems. While feeder circuits terminate in branch overcurrent protective devices, branch circuits terminate in loads. A feeder diagram may be required before installation, detailing the total load, sizing, type of feeder conductors, and rating of the feeder overcurrent protective devices.

Line feed in computer science: pressing Enter in a text document is a line feed
In the context of electrical systems, the term "feed" is used to refer to the electrical wires that deliver power or electrical current from the source to a device. These are called "line wires" and are usually black, though this is not always the case. Line wires are always "hot", meaning they carry an electrical current and act as the "supply lines" of electrical power.
Now, let's turn our attention to the concept of a "line feed" in computer science. When you press Enter in a text document, it is represented as a line feed (LF) and a carriage return (CR) on Windows operating systems. On other operating systems, such as Linux or Mac, it is represented by a single LF character. These are special characters that are usually not shown by default in most visual editors.
The term "line feed" originally referred to advancing paper in a printer or typewriter by one line. It instructed the printer to move the paper forward by a single increment. This is analogous to a carriage return on a typewriter, where the lever is moved to change the position of the next letter to the beginning of the line.
In the context of computer screens, a line feed now also means moving the cursor forward by one line. So, when you press Enter, you are instructing the computer to create a new line, just as you would advance the paper in a typewriter or printer.
This understanding of a line feed as pressing Enter in a text document is specific to computer science and text editing. It is important to distinguish it from the usage of "feed" in electrical systems, where it refers to the line wires delivering power.
