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 Non- Metallic 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 non- metallic 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 non- metallic 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 Non- Metallic Conduit Commonly used to connect underground lines to a service entrance panel.
