  1. On a wiring diagram, two wires that cross without a dot at the intersection indicate:

    Answer: Wires that cross but are not connected

    A crossing without a dot means the wires pass over each other on the diagram but do not make an electrical connection.

  2. A dishwasher blueprint shows a component labeled 'NTC.' During recycling inspection, this component is identified as a:

    Answer: Negative temperature coefficient thermistor (temperature sensor)

    NTC refers to a Negative Temperature Coefficient thermistor, a sensor whose resistance decreases as temperature rises.

  3. When a blueprint cross-references 'See Detail A,' the technician should expect Detail A to show:

    Answer: A magnified view of a specific area with more precise dimensions

    Detail views provide an enlarged, more precise depiction of a specific area that is too small or complex to show clearly on the main drawing.

  4. On a refrigerator parts diagram, the 'BOM' is used during recycling to:

    Answer: Identify hazardous materials and material types for each part number

    The Bill of Materials (BOM) lists every part with its material composition, which is essential for sorting recyclable materials and identifying hazardous components.

  5. A schematic symbol showing a zigzag line represents which electrical component?

    Answer: A resistor

    A zigzag line is the standard ANSI/IEEE symbol for a resistor, which opposes the flow of electric current.

  6. In appliance blueprints, 'AWG' next to a wire callout refers to:

    Answer: Appliance Wiring Gauge — the wire diameter standard used in the US

    AWG stands for American Wire Gauge, the standard US system for specifying wire conductor diameter; lower AWG numbers indicate thicker wires.

  7. A blueprint note reads 'TYP.' next to a dimension. This abbreviation means the dimension:

    Answer: Applies to all similar features throughout the drawing

    'TYP.' is short for 'typical' and indicates that the noted dimension or detail applies to all identical features, not just the one it is adjacent to.
