Black means hot white signifies neutral and green indicates ground. The white neutral wire is splice to each outlet so they share the return path.
How To Add A Switch
I have 2 black wires and 2 white wires outlet. If the fixture has leads connect the two existing white wires to the white lead. At the wall switch connect the black wire from the new piece of romex to the bottom screw. Three wire cable runs into the box. So can i extend the black and white from the existing 2 wire receptacle to new location and install a 2 wire outlet or gfci outlet but leave the romex ground not connected at each end.

Its essential that you determine which black wire is hot before proceeding. It is common to feed thru an outlet in other words to bring the power in on one trio of wires tied to the outlet and send it out on another trio of wires also tied to the outlet. The easiest and safest way is to use a multimeter to test for current. Thanks for asking robert lets clarify this question. In this diagram two outlets are wired in the same box with a separate 120 volt source feeding each. You take a short length of black wire roughly 6 8 inches of the same gauge as the wires in the wall then you take your two blacks and you twist all the ends together and marrette them.
Wiring 2 outlets with 2 sources. The black and red wires are both hot and each is connected to one of the receptacles. You then repeat this with the white wires with a short length of white wire. However if you need to rewire a light switch or a plug socket you may occasionally come across two black wires. Connect the two existing white wires at the light fixture to the silver screw of the light fixture. Basically the procedure is simple.
