The load wire is always hot black or red wire and the line wire is the one that returns to your fusebox usually white. Comes in from the electrical panel.

Line vs load wire. The neutral wire complete the circuit to the power panel and provides a return path for the electrical circuit. If the wire is coming from the top of the switch box it is likely your load wire. Load wire generally connected to the top half of your switch. Non gfci circuits will not have a load. Line wire generally connected to the bottom half of your switch. Line load neutral ground scott wiersdorf on reference.
I re learned some electrical terms today that may be useful later when working with gfci circuits. When referring to an electric device that can be connected to another one such as a receptacle line refers to the wires feeding it from the panel which is upstream from the device in terms of the flow of electricity. It is very important to wire line and load when it is called for. In some cases line wires are marked with line pwr or a lightning bolt symbol. The white neutral wire connects to the silver colored screw terminal marked line. The line wire is the one that supplies voltage to the devices from the power line circuit breaker.
The load wire is connected to the device being installed. Line usually black also known as hot. The circuits hot wire typically colored black or red connects to the black or brass colored screw terminal marked line. Answer above is absolutely wrong written by someone who does not. Load usually black sometimes red. Completes the ac circuit and carries excess current to ground.
With the first device the line is the wire running from the service panel to the device and the load is the wire running from the first device to the second device downstream on the circuit. The markings for line and load usually are printed on the back of the outlets plastic body. Is a continuation of line and goes out to downstream devices. On the other hand load refers to devices on the same circuit that are downstream of the one in question.
