At the second device the line is the power source coming in from the first device. Protected receptacle s will be connected to the gfci load side as shown below. However only 2 of them are fed from the load side of the gfci. The above switch wiring diagram shows a different wire color coding than what is used in the usa.
To wire a single gfci simply connect the source conductors to the line side of the. The other outlet is pigtailed from the line side of the gfci.
