1On a New Mexico commercial and industrial EE-98 Part 1 installation, what is the minimum depth of working space in front of a 208Y/120-volt switchboard where exposed live parts are on one side and no live or grounded parts are on the other side (Condition 1)?
A.2 feet 6 inches
B.3 feet
C.3 feet 6 inches
D.4 feet
Explanation: NEC 110.26(A)(1) and Table 110.26(A)(1) require 3 feet of working space for Condition 1 where the voltage to ground is 0–150 volts. A 208Y/120-volt system is 120 volts to ground, so the 3-foot column applies.
2Per NEC Article 100, which conductors are classified as a feeder?
A.The conductors between the service point and the service disconnecting means
B.The conductors between the final overcurrent device and the outlets
C.All circuit conductors between the service equipment, a separately derived system, or other power-supply source and the final branch-circuit overcurrent device
D.Only the ungrounded conductors leaving a transformer secondary
Explanation: NEC Article 100 defines a feeder as all circuit conductors between the service equipment, the source of a separately derived system, or other power-supply source and the final branch-circuit overcurrent device. That definition is used throughout commercial load and conductor calculations on EE-98 Part 1.
3What dedicated equipment space is required above a floor-mounted 480-volt switchboard, other than the structural ceiling, in a commercial electrical room?
A.3 feet above the enclosure
B.4 feet above the enclosure or to the structural ceiling, whichever is lower
C.6 feet above the enclosure or to the structural ceiling, whichever is lower
D.The full height of the room with no foreign systems permitted anywhere above the equipment
Explanation: NEC 110.26(E)(1)(a) requires a dedicated equipment space equal to the width and depth of the equipment and extending from the floor to a height of 6 feet above the equipment or to the structural ceiling, whichever is lower. Foreign systems are restricted in that zone unless isolation and protection rules are met.
4Except as permitted by the exceptions in NEC 110.26(A)(3), what is the minimum headroom of working space about service equipment, switchboards, switchgear, panelboards, or motor control centers?
A.6 feet
B.6 feet 6 inches
C.7 feet
D.7 feet 6 inches
Explanation: NEC 110.26(A)(3) requires the work space to be clear and extend from the grade, floor, or platform to a height of 6 feet 6 inches or the height of the equipment, whichever is greater. NMAC 14.10.4.11 adds a limited well-pump-enclosure exception, but the general commercial rule remains 6 feet 6 inches.
5At a service supplying a commercial occupancy, where must the available fault current and the date the calculation was performed be field marked?
A.Only on the utility transformer nameplate
B.On the service equipment
C.Only in the engineer’s sealed drawings
D.On every branch-circuit panelboard in the building
Explanation: NEC 110.24(A) requires service equipment in other than dwelling units to be legibly field marked with the maximum available fault current and the date the fault-current calculation was performed. The marking must be able to withstand the environment involved.
6What is the minimum width of the working space in front of a 36-inch-wide commercial panelboard?
A.24 inches
B.30 inches
C.36 inches
D.42 inches
Explanation: NEC 110.26(A)(2) requires the working-space width to be the width of the equipment or 30 inches, whichever is greater. For a 36-inch-wide panelboard the equipment width governs, so 36 inches is required. In all cases the working space must permit the enclosure door or hinged panel to open at least 90 degrees.
7How must a grounded (neutral) conductor 6 AWG or smaller generally be identified?
A.Green insulation or green with yellow stripes
B.A continuous white or gray outer finish, or three continuous white or gray stripes on other than green insulation
C.Orange insulation
D.Black insulation with a field-applied red phase tape
Explanation: NEC 200.6(A) requires grounded conductors 6 AWG or smaller to have a continuous white or gray outer finish, or three continuous white or gray stripes on other than green insulation, unless a listed exception applies. Green is reserved for grounding, and orange identifies a high-leg.
8Unless the equipment is listed and marked otherwise, conductor ampacity used at terminations rated 100 amperes or less, or marked for 14 AWG through 1 AWG conductors, shall be selected from which temperature column of Table 310.16?
A.60°C column
B.75°C column
C.90°C column
D.The insulation rating printed on the conductor only, without regard to the terminal
Explanation: NEC 110.14(C)(1)(a) requires the 60°C ampacity column to be used for terminations rated 100 amperes or less, or marked for 14 AWG through 1 AWG conductors, unless the equipment is listed and identified for use with 75°C conductors. THHN’s 90°C rating may be used for adjustment and correction, but the termination still limits the final ampacity.
9What is the minimum vertical clearance above a public street, alley, road, or parking area subject to truck traffic for 120/240-volt overhead service-drop conductors?
A.10 feet
B.12 feet
C.15 feet
D.18 feet
Explanation: NEC 230.24(B)(4) requires 18 feet of vertical clearance above public streets, alleys, roads, parking areas subject to truck traffic, driveways on other than residential property, and other land traversed by vehicles such as cultivated, grazing, forest, and orchard. The 10-foot and 12-foot values apply to more limited areas.
10A commercial feeder supplies an 80-ampere continuous load and a 40-ampere noncontinuous load. What is the minimum conductor ampacity required by NEC 215.2(A)(1) before any adjustment or correction factors?
A.120 amperes
B.130 amperes
C.140 amperes
D.150 amperes
Explanation: NEC 215.2(A)(1) requires feeder conductors to have an ampacity not less than 125 percent of the continuous load plus 100 percent of the noncontinuous load: (80 A × 1.25) + 40 A = 100 + 40 = 140 A. The same 125-percent continuous-load rule appears in 215.3 for the feeder overcurrent device.
