Standards Addressed!
• PST.01.02. Apply physical science and engineering principles to
design, implement and improve safe and efficient mechanical
systems in AFNR situations.
• PST.01.02.02.a. Identify the tools, machines and equipment needed
to construct and/or fabricate a project in AFNR.
Adapter
• Placed on the end of a cord to adapt a two
prong plug to a three prong plug. The
green eyelet is attached to the center
screw of the receptacle cover for
grounding.
Armored Cable
•Used mainly for inside wiring. Consists of
metal armor and each of the copper
conductors insulated by plastic or rubber
insulation.
Cartridge Fuse
•A device that will open a circuit and stop the
flow of current when an overload or short
occurs. This fuse appears in a cylinder
shape with smooth ferrules at both ends.
Circuit breaker
(three-pole; two
pole)
•Protective device which protects the circuit
from overload. When an overload occurs,
the breaker will trip, automatically opening
the circuit.
Circuit Tester
(AC or DC)
•A simple device used to test the circuit and
determine if power is on or off.
Clamp-on
Circuit Tester
•A portable testing instrument that snaps
around the conductor to measure AC
amperage.
Conduit Bender
•Used to bend angles in thin-walled conduit.
Cord Cap
•Used as a male plug. The cord cap is used
on power tools as well as appliances in the
home.
Cord Connector
•Designed to accommodate the cord the
cord cap and is sometimes referred to as the
female plug.
Dimmer Switch
• A electric light switch that may be used to
apply partial power to a light fixture.
Duplex
Receptacle
•A plug for electrical devices which will
accommodate two plugs (cord caps) at the
same time.
EMT Connector
• Used to connect two pieces of conduit end
to end.
EMT Elbow
• Allows a corner to be made when
connecting two pieces of conduit.
Fishing Tape
•Used to pull electrical wires through
conduit.
Flexible Metallic
Conduit
•A piece of spiral shaped, interlocking zinc
coated steel used to protect wiring.
Flexible NonMetallic Conduit
•Commonly used to connect stationary
equipment to a power source.
Fuse Puller
•Used to pull or install cartridge and knife
fuses.
Ground Fault
Interrupter
•An electric outlet commonly used in areas
where water is present. Provides additional
safety as it contains a breaker mechanism.
Insulated Staple
•A staple used to fasten low voltage wires to
structures and has a double fold of
insulation over the galvanized staple.
Junction Box
•Device used for housing splices and
mounting different types of electric fixtures.
Key Stock
• A square metal stock in various sizes that
is placed in a round shaft to hold pulleys
and pillow blocks in place. (could be used
with electric motors or on small gas
engines)
Knife Fuse
•It is another type of cartridge fuse and is
rated for electrical service of 60 to 600
amperes.
Multi-Meter
•A specifically designed meter used to
measure AC or DC voltage, current, and
ohms with accuracy.
Non-Metallic
Cable
•Must be used for inside wiring. Consists of
a thermoplastic sheath, insulated
conductors, and is available with or without
grounding wire.
Non-Metallic
Cable Ripper
•Used to aid in the removal of the nonmetallic cable insulation in order to expose
the insulated wires inside.
Non-Metallic
Clamp
•Used to fasten non-metallic cable to boxes.
Plastic Covered
Electric Cord
•Used for household appliances. The
stranded copper conductors are covered
with plastic insulation.
Rigid Conduit
•Used both inside and outside to provide
mechanical and fire protection for wiring.
Romex Clamp
•A specifically designed camp for nonmetallic sheath cable in switch boxes.
Rubber Covered
Electric Cord
•The copper conductors are individually
insulated and wrapped with paper.
Service
Entrance Panel
The entry point for electrical power into a
building. Circuit breakers are connected into
the electrical system at this point.
Electric
Soldering
Iron/Gun
•Used as a source of heat for metals being
joined by soldering.
Solderless
Connector
•Used for splicing electrical wiring without
the use of solder or tape.
Switch Box
•Used to mount switches or receptacles
flush in the wall.
Thermoplastic
Electric Wire
(TW)
•Most commonly used for conductors in
nonmetallic cable.
Thin-Walled
Conduit
•Also referred to as Electrical Metallic Tubing
(EMT) which is used inside to provide
mechanical and fire protection.
Three Way
Toggle Switch
•An electrical device used to control a circuit
from two different locations. The name of
the three way switch is derived from its three
terminals on the switch.
Toggle Switch
•Electrical device used to open and close a
circuit from one location.
Uni-Bit
• A cone shaped drill bit commonly used to
drill holes for conduit in metal boxes or
metal siding.
Water Proof Box
• A variety of electrical boxes designed for
external use where they are exposed to
weather.
Wire Nuts
• Used to connect electrical wires rapidly
without the use of tape.
Water Proof
Tape
•Self-Sealing tape which chemically bonds
itself to produce a waterproof splice.
Wire Solder
•Used for soldering sheet metal seams,
electrical connections and other repair work.
It is available in solid or flux-cored wire.
Wire Stripper
•Used to remove insulation from wire without
damaging the wire.
Wire Terminals
• Crimped onto the end of wire so that the
wire may be attached to a screw or
terminal.
Plug Fuse
•A protective device used for overloads up to
30 amperes.
Rigid NonMetallic Conduit
•Commonly used to connect underground
lines to a service entrance panel.
