Two black wires in outlet. On 2020 03 04 by mod where do i connect ground wire when i only have two wires. If an outlet commonly called a receptacle no longer holds a plug snugly it should be replacedthe procedure for replacing a duplex two outlet wall receptacle is similar to that of replacing a switch. Thanks for asking robert lets clarify this question. Put the black and red wires into the hot ports on the back of the outlet. To direct wire through the receptacle connect one of the black hot circuit wires to one of the brass colored terminals and connect the other black wire to the other brass terminal. The easiest and safest way is to use a multimeter to test for current.
One of the hot wires attaches to a brass terminal on one side of the outlet and the other attaches to a brass terminal on the other side. However if you need to rewire a light switch or a plug socket you may occasionally come across two black wires. Learn how to identify wires for your safety. There will be 2 unlabeled screws left on the back of the outlet which are known as the hot screws. Place the end of the black wire in the port next to one of the unlabeled screws and the red wire in the port on the other. The hot and neutral lines should be two distinct colors but the colors can vary for the different wires.
The normal colors of a residential outlet are black hot white nuetral and baregreen ground. Its essential that you determine which black wire is hot before proceeding. Black means hot white signifies neutral and green indicates ground. Similarly each white neutral wire is connected to a silver neutral terminal. 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. The only difference is that depending on where the receptacle is located in the wiring scheme of your house it may have more wires attached to it than you find attached to a light switch.
It is common to feed thru an outlet in other words to bring the power in on one trio of wires.
