I have 6 GFI outlets in my kitchen of which 2 don't seem to work. There
is current going to each one. I don't understand why all the outlets are
A GFI receptacle monitors the current entering and leaving through the
hot and neutral sides. If the current is not equal it means that the current
is leaving the intended path and is flowing through some sort of conductive
material such as a piece of metal or perhaps a person. The receptacle
senses this and stops the current from flowing.
Pressing the reset button should restore the power, if it fails to reset
it should be replaced. If your kitchen is on one circuit you only need
one GFI for the entire circuit. The GFI must be the first outlet on the
circuit in order to protect the whole circuit.
How can I test the GFCI that my electrician installed?
The GFCI is shipped from the factory in the tripped condition and cannot
be reset until it is wired correctly and power is supplied to the device.
Plug a lamp into the GFCI and turn the power on at the service panel.
Press the Test button; if the indicator light on the receptacle is on
and the lamp is not; the line and load connections are reversed.
Press the reset button. If the indicator light goes on and the lamp also
turns on; the GFCI has been installed correctly.
Press the test button every month to assure the GFCI is working properly.
If the indicator light does not go out and come back on or if the GFCI
can not be reset, it must be replaced.
Why are the wires in my electric outlet different colors?
Regardless of the type of wiring you have in your home, here are some
basics to remember:
The white wire is usually the neutral wire, but sometimes wiring installation
requires it to be a hot wire. If the white wire is the hot wire, code
it black with paint or electrical tape. A previous installer may not have
coded the wire so be careful. If a red wire is present, it should also
The black wire is "hot."
The exposed copper wires are ground wires.
How do I know if an outlet is at the beginning or end of a circuit?
If a single cable enters the box (or one set of black and white wires),
the fixture is at the end of the circuit. This is usually, but not always,
the situation with ceiling light fixtures.
If two cables enter the box (or two sets of black and white wires in older
"knob and tube" installations), the fixture is in the middle
of a circuit.
A third cable (or set of black and white wires) may also enter the fixture,
depending upon the installation. The placement of the fixture within the
circuit affects how it is wired.
