Prepare with NEC 2023 and Rhode Island amendments. DLT’s Certificate B examination requires 70% to pass; the application processing fee is $75, with licensing costs separate. Do not assume an 80-question/four-hour format or permission to use a bound codebook: confirm timing and permitted references with DLT.

Sample RI Electrician Practice Questions

Try these sample questions to review concepts for the RI Electrician exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 307+ question experience with AI tutoring.

1According to the NEC, what is the definition of a 'branch circuit'?
A.The circuit conductors between the service point and the main disconnecting means
B.The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s)
C.Any circuit that supplies power to a motor
D.The conductors between the transformer and the first overcurrent device
Explanation: Per NEC Article 100, a branch circuit is defined as the circuit conductors between the final overcurrent device protecting the circuit and the outlet(s). This definition is fundamental to understanding how the NEC organizes and regulates different parts of an electrical system.
2In Rhode Island, the Electricians' Examination & Licensing Board oversees journeyman electrician licensing. What is the NEC edition currently adopted by Rhode Island?
A.NEC 2017
B.NEC 2020
C.NEC 2023
D.NEC 2026
Explanation: Rhode Island currently uses the 2020 NEC edition. The RI Electricians' Examination & Licensing Board administers the exam directly (state-administered, not PSI). Rhode Island typically adopts NEC editions on a delayed cycle compared to some states.
3Per NEC 210.8(A), GFCI protection is required for all 125-volt through 250-volt receptacles in which of the following dwelling unit locations?
A.Living rooms
B.Bedrooms
C.Kitchens
D.Closets
Explanation: NEC 210.8(A) requires GFCI protection for 125-volt through 250-volt receptacles in dwelling unit kitchens, along with bathrooms, garages, outdoors, crawl spaces, basements, and other specified locations. The 2023 NEC expanded GFCI requirements significantly.
4What is the minimum size equipment grounding conductor required for a 60-ampere circuit per NEC Table 250.122?
A.14 AWG copper
B.12 AWG copper
C.10 AWG copper
D.8 AWG copper
Explanation: Per NEC Table 250.122, a 60-ampere overcurrent device requires a minimum 10 AWG copper equipment grounding conductor. This table is based on the rating of the overcurrent device protecting the circuit, not the conductor ampacity.
5According to NEC 250.66, what is the minimum size grounding electrode conductor for a 2/0 AWG copper service conductor?
A.8 AWG copper
B.6 AWG copper
C.4 AWG copper
D.2 AWG copper
Explanation: Per NEC Table 250.66, for service conductors sized 2/0 AWG copper (or 4/0 AWG aluminum), the minimum grounding electrode conductor is 4 AWG copper or 2 AWG aluminum. This table correlates the size of the largest service-entrance conductor with the required grounding electrode conductor.
6What is the standard voltage drop recommendation for branch circuits per NEC 210.19(A) Informational Note No. 4?
A.2%
B.3%
C.5%
D.8%
Explanation: NEC 210.19(A) Informational Note No. 4 recommends that voltage drop on branch circuits should not exceed 3%, and the total voltage drop for feeders and branch circuits combined should not exceed 5%. While these are recommendations rather than requirements, they represent good practice.
7Per NEC Table 310.16, what is the ampacity of a 6 AWG THWN-2 copper conductor at 75°C column?
A.40 amperes
B.55 amperes
C.65 amperes
D.75 amperes
Explanation: Per NEC Table 310.16, a 6 AWG copper conductor with a 75°C insulation rating (such as THWN-2 used at 75°C) has an ampacity of 65 amperes. THWN-2 is rated for 90°C but is commonly used at the 75°C column when terminated at equipment rated for 75°C.
8According to NEC 314.16(B), what is the volume allowance for each 12 AWG conductor in a box fill calculation?
A.2.00 cubic inches
B.2.25 cubic inches
C.2.50 cubic inches
D.3.00 cubic inches
Explanation: Per NEC Table 314.16(B), each 12 AWG conductor requires a volume allowance of 2.25 cubic inches in a box fill calculation. This includes equipment grounding conductors counted as one conductor, device yokes counted as two conductors, and clamps counted as one conductor.
9Per NEC 430.52, what is the maximum size dual-element time-delay fuse permitted for motor branch-circuit short-circuit and ground-fault protection for a standard AC motor?
A.125% of motor FLC
B.150% of motor FLC
C.175% of motor FLC
D.250% of motor FLC
Explanation: Per NEC Table 430.52, the maximum rating for a dual-element time-delay fuse used for motor branch-circuit short-circuit and ground-fault protection is 175% of the motor's full-load current. If 175% does not correspond to a standard fuse size, the next higher standard size may be used.
10What is the minimum height above grade for service drop conductors over a residential driveway?
A.10 feet
B.12 feet
C.15 feet
D.18 feet
Explanation: Per NEC 230.24(B)(1), service drop conductors must maintain a minimum clearance of 12 feet above residential driveways and commercial areas not subject to truck traffic. This clearance ensures safe passage of vehicles beneath the conductors.
