Glossary E - N
|Feed Wire: A conductor that
carries 120-volt current uninterrupted from the service
panel. This is the wire that runs through your home to all
the outlets and receptacles.
Fuse: A safety device, usually found in older homes,
that interrupts electrical circuits during an overload or
short circuit. A fuse is an older version of today’s circuit
Grounded Wire: A grounded wire is another name for
the neutral wire.
Grounding Wire: This wire is used in an electric
circuit to conduct current to the earth in the event of a
short circuit. This protects your home in the event of an
overload. The grounding wire is often a bare copper wire.
GFI: Ground Fault Interrupter. This is a special
receptacle that provides shock protection for the entire
circuit. GFI outlets are used in bathrooms, kitchens, and
outside receptacles; or anywhere you may come in contact
Hot Wire: Any wire that carries voltage. In an
electrical circuit, the hot wire is usually covered in black
or red insulation. When you are installing any receptacle,
it will have a hot wire to provide the electricity, a
neutral wire that returns the current to the source of the
power with no voltage, and a ground wire.
Insulator: Any material such as plastic or rubber;
that resists the flow of electrical current. The job of the
insulator is to protect the wire.
Junction Box: The box used to contain wiring
Meter: A device used to measure the amount of
electric power being used.
Neutral Wire: A wire that returns the current at zero
voltage to the source of electrical power. This wire is
usually covered in white or light gray rubber or vinyl and
is a part of every receptacle. The neutral wire is also
called the grounded wire.
