EIAT and NEIEP Test Print Reading and Blueprints 3 — Questions and Answers
Question 1: What do the letters 'EMT' stand for on conduit schedule drawings?
- Electrical Metal Terminal
- Electrical Metallic Tubing (Correct answer)
- Embedded Metal Track
- Emergency Metal Tray
Correct answer: Electrical Metallic Tubing
EMT (Electrical Metallic Tubing) is thin-walled metal conduit commonly used for exposed interior wiring runs in commercial and industrial buildings.
Question 2: On architectural drawings, what does 'AFF' stand for?
- Allowance for Finish
- Above Finished Floor (Correct answer)
- Adjacent to Fire Frame
- Appliance Fixture Frame
Correct answer: Above Finished Floor
AFF (Above Finished Floor) is a measurement reference indicating a height measured from the completed floor surface.
Question 3: On an isometric drawing of a conduit system, what is the main advantage over an orthographic drawing?
- More accurate dimensions
- Shows three dimensions in a single view without multiple projections (Correct answer)
- Smaller file size
- Easier to dimension in 2D software
Correct answer: Shows three dimensions in a single view without multiple projections
Isometric drawings show height, width, and depth in a single view at 30° angles, making 3D routing of conduit easier to visualize.
Question 4: A conduit home-run arrow on a floor plan typically points toward:
- The nearest outlet box
- The distribution panel serving those circuits (Correct answer)
- True north
- The building entrance
Correct answer: The distribution panel serving those circuits
Home-run arrows indicate the direction and panel/circuit designation where conductors route back to the panel that feeds that circuit.
Question 5: What information does a 'lighting fixture schedule' on a set of drawings provide?
- The wiring method for each fixture
- A table listing each fixture type, manufacturer, model, watts, and mounting details (Correct answer)
- HVAC load calculations
- The panel location for each fixture
Correct answer: A table listing each fixture type, manufacturer, model, watts, and mounting details
A lighting fixture schedule is a reference table that cross-references fixture type symbols on the plan to specific product specifications and mounting details.
Question 6: On electrical drawings, the symbol for a duplex receptacle outlet is typically:
- A square with two dots
- A circle with two parallel lines (like a capital letter 'D' with a line) (Correct answer)
- A triangle pointing left
- An 'X' inside a square
Correct answer: A circle with two parallel lines (like a capital letter 'D' with a line)
A standard duplex receptacle is drawn as a circle with two parallel lines extending from it, representing the two plug slots.
