✍️ Sample TN LLE Questions & Answers

1. Per NEC 314.28(A)(2), what is the minimum distance calculation for an angle pull in a pull box with a 3-inch conduit?

✓ 18 inches (6 x 3)

For an angle pull, NEC 314.28(A)(2) requires 6 times the trade size of the largest raceway entering that wall. 6 x 3 = 18 inches minimum, plus the sum of other raceways on the same wall.

2. A 10 AWG copper conductor has approximately 1.21 ohms per 1,000 feet. What is the voltage drop for a 150-foot one-way run carrying 25 amperes?

✓ 9.08 volts

Voltage drop = 2 x Length x Resistance per foot x Current = 2 x 150 x (1.21/1000) x 25 = 9.08V.

3. In the NEC, what does the term "Readily Accessible" mean?

✓ Capable of being reached quickly for operation, renewal, or inspections without requiring tools to open doors or climbing over obstacles.

Article 100 defines "Readily Accessible" as capable of being reached quickly for operation or inspection without requiring tools to open doors, climbing over obstacles, or using a portable ladder. This is a higher level of accessibility than just "Accessible."

4. Per NEC 210.8(A), GFCI protection is required for 125V through 250V receptacles in which dwelling unit locations?

✓ Bathrooms, kitchens, garages, outdoors, crawl spaces, basements, and other specified locations

NEC 210.8(A) lists numerous dwelling locations requiring GFCI protection including bathrooms, garages, outdoors, crawl spaces, basements, kitchens, and several other specified areas.

5. What type of overcurrent protection is required for flexible cords and fixture wires per NEC 240.5?

✓ Overcurrent protection based on NEC Table 400.5(A)(1) cord ampacity values

NEC 240.5 addresses overcurrent protection for flexible cords and fixture wires, referencing Table 400.5 for cord ampacity.

6. Per NEC 430.102, a motor disconnecting means must be located where relative to the motor?

✓ Within sight from the motor location and the controller

NEC 430.102(A) and (B) require the motor disconnect to be within sight from the controller location, and 430.102(B) requires a disconnect within sight from the motor.
