The color for the Line wire is usually black and Load wire is usually red, black, or blue (less common).
.
Correspondingly, which wire is load and which is line?
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.
Similarly, how do you know which wire is black or line? Line Connection 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. The markings for line and load usually are printed on the back of the outlet's plastic body.

In a standard switch/dimmer, the "hot" is using one of the two wires connected to the switch.What happens if you switch line 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.What is common wire?
