Complete the wiring diagram, connecting feed-through GFCI 2 to also protect receptacle 1, both to be supplied by Circuit A1. Connect feed-through GFCI 3 to also protect receptacle 4, both to be supplied by Circuit A2. Use colored pencils or markers to show proper color. Assume that the wiring method is EMT, where more freedom in the choice of insulation colors is possible.
