Hook up gfci outlet 4 wires

The GFCI breaker has a protected "hot" conductor, a separate neutral connection, as well as a test and reset button. It will protect all devices on that entire branch, if properly installed.

Shared-neutral circuits must use the same 2-pole breaker

Don't attempt this one as a DIY job if you don't have extensive electrical experience. It can be very dangerous to work on exposed circuit breakers, even if you believe the main breaker or feed has been disconnected. There could be a ground fault, or the GFCI was wired improperly or is faulty. Not Helpful 0 Helpful 1.

GFCI Receptacle with 4 wires and a ground

Yes, it's possible, but probably pointless and potentially trouble-causing when both trip and you have to remember to reset both, or when one becomes more sensitive than the other. Yes, a GFCI can be powered from another outlet, a "regular outlet" if you're referring to a receptacle outlet and not a lighting outlet. A GFCI without a grounding wire will not provide "ground," but the mechanism to trigger upon a "ground fault" will work because it does not involve the ground wire - it only measures the current to and from the hot and neutral wires to make sure they are identical.

The momentary electrical surge when a motor starts can cause the breaker to trip. It is fine in a bathroom, since hair dryers and shavers do not draw a lot of current. They should also not be wired where a sump pump is connected, since an accidental trip could knock out the pump, resulting in a flooded basement.

Refer to the instructions that came with your specific GFCI, because the directions can differ slightly from manufacturer to manufacturer. Additional places required to have GFCI protection, other than bathrooms, under the NEC, if serving receptacles with volts at 15 or 20 amps: There are limited exceptions for outdoor receptacles used exclusively for de-icing and not readily accessible.

Also, a receptacle that supplies a permanently installed alarm system is not required to have GFCI protection in a basement. Warnings Turn off the electricity to the circuit being worked on to avoid possible electrocution. Refer to your particular product's troubleshooting guide or contact an electrician if your GFCI test fails.

GFCI breakers are for main electricity panels and should only be installed by a qualified electrician. Things You'll Need Phillips and flat-head screwdrivers. Did you try these steps?

Home Questions Tags Users Unanswered. Tobin Tobin 18 4. Simply saying "GFCI outlets will not work with shared neutrals" is incorrect.

They cannot be used with split-wired receptacles, but pig-tailing from shared neutral circuits is typically fine, depending on how the circuit is wired.


Are you sure the tabs on the existing outlet are intact? What is the name for that prong-style of outlet?

It looks like it has two "T"s. Jun 4 '16 at 2: Tester Tester k 54 Just a quick correction, GFCI receptacle devices pretty much all use "back wired" terminals. These are terminals where the wire is stuck into a hole in the back of the device and a screw plate is tightened. Typically there are two holes at each screw and it is perfectly legal and safe to put two wires, one in each hole. I know Tester means one wire per binding screw terminal, but back-wired terminal are different.

If only 1 black, 1 white and 1 green or bare wire are present in the electrical outlet box you can skip past this step. Line and load will be clearly labeled on the back of the GFCI outlet and often times the load side will be covered with a piece of tape. Refer to the diagram above about wiring GFCI receptacles for additional help.

Double check steps 5 and 6 and inspect the line side black conductor for damage. If the reset button will not reset make sure the line and load wires are terminated properly as described in step 5. Also inspect the load side black and white conductors for damage and make sure the ground conductor is not coming into contact with any other screws on the receptacle.

The back of these outlets are clearly marked line and load. It is important to know which is which before beginning. They usually come from the factory with a piece of tape covering the load connection points for further identification. The line terminals of a GFCI outlet connect to the power supply conductors that are connect at the circuit breaker or fuse box. Line essentially means supply.
