Bell Work!

• Explain the difference between
• AC and DC power.
• What is the advantage of 220 vs 110 power for
  shop equipment?
• What is three phase electricity?
• Which is better a fuse or circuit breaker?

4
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.

5
Armored Cable

• Used mainly for inside wiring. Consists of metal
  armor and each of the copper conductors insulated
  by plastic or rubber insulation.

6

  flow of current when an overload or short occurs.
  This fuse appears in a cylinder shape with
  smooth ferrules at both ends.

7
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.

8

• Used to bend angles in thin-walled conduit.

11
Cord Cap

• Used as a male plug. The cord cap is used on
  power tools as well as appliances in the home.

12
Cord Connector

• Designed to accommodate the cord the cord cap and
  is sometimes referred to as the female plug.

13
Dimmer Switch

• A electric light switch that may be used to apply
  partial power to a light fixture.

14
Duplex Receptacle

• A plug for electrical devices which will
  accommodate two plugs (cord caps) at the same
  time.

15
EMT Connector

• Used to connect two pieces of conduit end to end.

16
EMT Elbow

• Allows a corner to be made when connecting two
  pieces of conduit.

17
Fishing Tape

• Used to pull electrical wires through conduit.

18
Flexible Metallic Conduit

• A piece of spiral shaped, interlocking zinc
  coated steel used to protect wiring.

19
Flexible Non-Metallic Conduit

• Commonly used to connect stationary equipment to
  a power source.

20
Fuse Puller

• Used to pull or install cartridge and knife fuses.

21
Ground Fault Interrupter

• An electric outlet commonly used in areas where
  water is present. Provides additional safety as
  it contains a breaker mechanism.

22
Insulated Staple

• A staple used to fasten low voltage wires to
  structures and has a double fold of insulation
  over the galvanized staple.

23
Junction Box

• Device used for housing splices and mounting
  different types of electric fixtures.

24
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)

25
Knife Fuse

• It is another type of cartridge fuse and is rated
  for electrical service of 60 to 600 amperes.

26
Multi-Meter

• A specifically designed meter used to measure AC
  or DC voltage, current, and ohms with accuracy.

27
Non-Metallic Cable

• Must be used for inside wiring. Consists of a
  thermoplastic sheath, insulated conductors, and
  is available with or without grounding wire.

28
Non-Metallic Cable Ripper

• Used to aid in the removal of the non-metallic
  cable insulation in order to expose the insulated
  wires inside.

29
Non-Metallic Clamp

• Used to fasten non-metallic cable to boxes.

30
Plastic Covered Electric Cord

• Used for household appliances. The stranded
  copper conductors are covered with plastic
  insulation.

31
Rigid Conduit

• Used both inside and outside to provide
  mechanical and fire protection for wiring.

32
Romex Clamp

• A specifically designed camp for non-metallic
  sheath cable in switch boxes.

33
Rubber Covered Electric Cord

• The copper conductors are individually insulated
  and wrapped with paper.

34
Service Entrance Panel
The entry point for electrical power into a
building. Circuit breakers are connected into
the electrical system at this point.
35
Electric Soldering Iron/Gun

• Used as a source of heat for metals being joined
  by soldering.

36
Solderless Connector

• Used for splicing electrical wiring without the
  use of solder or tape.

37
Switch Box

• Used to mount switches or receptacles flush in
  the wall.

38
Thermoplastic Electric Wire (TW)

• Most commonly used for conductors in nonmetallic
  cable.

39
Thin-Walled Conduit

• Also referred to as Electrical Metallic Tubing
  (EMT) which is used inside to provide mechanical
  and fire protection.

40
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.

41
Toggle Switch

• Electrical device used to open and close a
  circuit from one location.

42
Uni-Bit

• A cone shaped drill bit commonly used to drill
  holes for conduit in metal boxes or metal siding.

  connections and other repair work. It is
  available in solid or flux-cored wire.

47
Wire Stripper

• Used to remove insulation from wire without
