Virginia - Journeyman Electrician

Key Concepts

Authority Having Jurisdiction (AHJ) — Defined in NEC Annex H (80.2) as the organization, office, or individual responsible for enforcing code requirements, approving equipment, materials, installations, or procedures. The AHJ has broad authority to interpret, enforce, and administer the NEC.

Scope of Enforcement (80.1) — The AHJ's authority covers: - Inspection of electrical installations - Investigation of fires caused by electrical installations - Review of construction plans, drawings, and specifications - Design, alteration, modification, construction, maintenance, and testing of electrical systems - Regulation of electrical installations at special events (trade shows, amusement parks, exhibits)

Key Concepts

Standards of Conduct for Virginia Journeyman Electricians are governed primarily by the Virginia Board for Contractors regulations and the Virginia Department of Professional and Occupational Regulation (DPOR). Key principles include:

License Requirements & Scope of Work - A Journeyman Electrician must work under the supervision of a licensed Master Electrician or Electrical Contractor. You may not independently contract electrical work. - Your license authorizes you to perform electrical work; it does not authorize you to pull permits or run a business as an independent contractor.

Key Concepts

License Expiration (18 VAC 50-30-120 A & B) - Electrician licenses expire three years from the last day of the month in which they were issued. - Most other licenses/certifications (not electricians, gas fitters, HVAC, or plumbers) expire in two years.

Continuing Education Requirement (18 VAC 50-30-120 C) - As a condition of renewal or reinstatement, individuals holding a tradesman license with an electrical designation must complete 3 hours of continuing education relating to applicable building code changes. - CE must come from a board-approved provider.

Renewal Fees (18 VAC 50-30-120 G) - Tradesman license renewal fee: $160.00 - All fees are nonrefundable and will not be prorated.

Key Concepts

Article 100 of the NEC 2020 defines terms used throughout the Code. Only terms used in two or more articles are defined here; single-article terms appear in the XXX.2 section of that specific article.

Critical Definitions to Know:

• Accessible (equipment): Capable of being reached for operation, renewal, and inspection.
• Accessible (wiring methods): Can be removed or exposed without damaging the building structure or finish.
• Readily Accessible: Reached quickly without tools (keys are acceptable), climbing, removing obstacles, or using portable ladders.
• Ampacity: Maximum current (in amperes) a conductor can carry continuously under conditions of use without exceeding its temperature rating.
• Approved: Acceptable to the Authority Having Jurisdiction (AHJ).
• Authority Having Jurisdiction (AHJ):…

Key Concepts

Governing Regulation: 18 VAC 50-30 (Individual License and Certification Regulations), administered by the Virginia Board for Contractors under the Department of Professional and Occupational Regulation (DPOR).

Key Definitions to Know:

• Journeyman (18 VAC 50-30-10): A person who possesses the necessary ability, proficiency, and qualifications to install, repair, and maintain specific types of materials and equipment, utilizing working knowledge sufficient to comply with the Virginia Uniform Statewide Building Code (VUSBC, 13VAC5-63) — and works according to plans and specifications.

• Master (18 VAC 50-30-10): A person qualified to plan, lay out details, and supervise installation, repair, and maintenance work. This distinguishes Master from Journeyman — supervision and planning authority belong to the Master level.

Key Concepts

Revocation of licensure in Virginia falls under the authority of the Virginia Board for Contractors, which oversees electrical licensing through the Department of Professional and Occupational Regulation (DPOR). While the NEC (Annex H) establishes enforcement frameworks, Virginia's licensing discipline is governed by Virginia Code § 54.1 and the Virginia Board for Contractors regulations (18 VAC 50-22).

Grounds for revocation include:

• Obtaining a license through fraud, misrepresentation, or false statement on an application
• Violating any provision of the NEC as adopted by Virginia, or applicable state/local codes
• Engaging in gross negligence, incompetence, or misconduct in the practice of electrical work
• Conviction of a crime that relates directly to the practice of electrical work or…

Key Concepts

Purpose of the NEC (Article 90.1) The NEC's purpose is the practical safeguarding of persons and property from hazards arising from the use of electricity. Critical distinction: the Code is not a design specification or instruction manual for untrained persons. Compliance produces an installation that is essentially free from hazard — but not necessarily efficient, convenient, or adequate for future expansion.

NEC Scope — What IS Covered (90.2(A)) The Code covers installation and removal of electrical conductors, equipment, and raceways for: - Public and private premises (buildings, structures, mobile homes, RVs, floating buildings) - Yards, lots, parking lots, carnivals, industrial substations - Conductors and equipment connecting to the electricity supply - Utility-owned office buildings, warehouses, garages, machine…

Key Concepts

This topic draws from NEC 2020 Article 110 (Requirements for Electrical Installations) and foundational definitions in Article 100. These rules apply broadly across all electrical work and establish the baseline standards every journeyman must know.

Article 110 Core Requirements:

• 110.2 — Approval: All electrical equipment must be acceptable to the authority having jurisdiction (AHJ). Equipment must be listed and labeled where required.
• 110.3 — Examination, Identification, Installation, and Use: Equipment must be installed and used in accordance with any instructions included in the listing or labeling. This is a frequently cited code basis for violations.
• 110.9 — Interrupting Rating: Equipment intended to interrupt current at fault levels must have an interrupting rating sufficient for…

Virginia Journeyman Electrician Exam

Key Concepts

This topic covers foundational electrical theory that underpins all NEC application. With only 2 questions at 3% of the exam, expect broad, concept-level questions rather than deep code-section lookups.

Ohm's Law — The relationship between voltage (E), current (I), and resistance (R): - E = I × R (Voltage = Current × Resistance) - Any two known values can solve for the third.

Power (Wattage) — The rate of electrical energy consumption: - P = E × I (Watts = Volts × Amps) - P = I² × R - P = E² / R

Key Concepts

Article 210 governs general branch circuit requirements. Know these sections cold:

210.4 — Multiwire Branch Circuits (MWBCs) - All conductors must originate from the same panelboard or distribution equipment (210.4(A)) - Must have a simultaneous disconnect for all ungrounded conductors at the point of origin — a 2-pole or 3-pole breaker (or handle-tied singles where permitted) (210.4(B)) - MWBCs shall supply only line-to-neutral loads — with two exceptions: - Exception 1: Circuit supplies only one utilization equipment - Exception 2: All ungrounded conductors are opened simultaneously by the OCPD (210.4(C))

Key Concepts

Article 220 — Branch-Circuit, Feeder, and Service Load Calculations

• 220.1 Scope: Article 220 governs how to calculate branch-circuit, feeder, and service loads. Parts III and IV specifically cover feeder and service load calculations. Part V covers farm loads.
• 220.5(A) Nominal Voltages: For load calculations, use standard nominal voltages: 120, 120/240, 208Y/120, 240, 347, 480Y/277, 480, 600Y/347, and 600 volts. Do not use measured or approximate voltages.
• 220.5(B) Rounding: Calculated amperage values may be rounded to the nearest whole ampere. Drop decimal fractions smaller than 0.5 (e.g., 47.4A = 47A; 47.5A rounds to 48A).

Article 215 — Feeders

Key Concepts

Article 200 – Grounded Conductor Identification

• 200.6(A): Grounded conductors 6 AWG or smaller must be identified by a continuous white or gray outer finish, three continuous white/gray stripes on non-green insulation, or other listed methods.
• 200.6(B): Grounded conductors 4 AWG or larger may alternatively be identified at terminations by a distinctive white or gray marking that encircles the conductor or insulation — applied at time of installation.
• 200.6(D): When grounded conductors of different systems share the same raceway, cable, or enclosure, each must be distinctly identified by system. The identification method must be documented and posted where conductors originate.
• 200.7: White, gray, or three-stripe conductors are reserved exclusively for grounded conductors — with…

Key Concepts

Article 200 — Use and Identification of Grounded Conductors

Insulation Requirements (200.2) - Grounded conductor insulation must be suitable for any ungrounded conductor on the same circuit (systems ≤1000V) - For solidly grounded neutral systems >1000V: insulation rated not less than 600V per 250.184(A) - Continuity of the grounded conductor cannot depend on connection to a metallic enclosure, raceway, or cable armor (200.2(B))

Neutral Conductor Rules (200.4) - A neutral conductor shall not serve more than one branch circuit, one multiwire branch circuit, or one set of ungrounded feeder conductors - Where multiple neutrals from different circuits share an enclosure, each must be identified or grouped with its corresponding…

Key Concepts

NEC Article 300 – General Wiring Methods

Same-Circuit Conductors (300.3(B)): All conductors of the same circuit — including the grounded conductor, equipment grounding conductors (EGCs), and bonding conductors — must be contained within the same raceway, cable, or enclosure. This prevents inductive heating and ensures proper overcurrent protection behavior.

Single Conductors (300.3(A)): Single conductors from Table 310.4(A) may only be installed as part of a recognized Chapter 3 wiring method. They cannot be run arbitrarily as standalone conductors — with the exception of overhead conductors per 225.6.

Key Concepts

Hazardous (Classified) Locations – Articles 500–506

• Class I locations contain flammable gases or vapors. Class II locations contain combustible dusts. Class III locations contain ignitible fibers or flyings.
• Division 1: Hazardous conditions exist under normal operations.
• Division 2: Hazardous conditions exist only under abnormal conditions (failure, accident, etc.).
• Zone system (Articles 505–506) is an alternative IEC-based classification. Zone 0/20 = most hazardous; Zone 2/22 = least hazardous among classified zones.
• All hazardous (classified) areas must be documented and that documentation must be available to those who design, install, inspect, maintain, or operate equipment (NEC 506.4).

Article 610 – Cranes and Hoists

Separate Controllers (610.51): Each motor requires its own individual controller. Exceptions: - Two or more motors driving a single hoist, carriage, truck, or bridge may share one controller. - One controller may be switched between motors only if: (1) its HP rating ≥ the largest motor's HP rating, and (2) only one motor operates at a time.

Overcurrent Protection for Control Circuits (610.53): Control circuit conductors must be protected at no more than 300% of conductor ampacity. - Taps to control transformers: protected at no more than 200% of rated secondary current and **200% of…

Key Concepts

This topic is governed by NEC Article 600, which covers electric signs and outline lighting, including neon tubing and LED signs. Key principles to know:

• Article 600.5 — Branch Circuits for Signs: Every commercial building or occupancy accessible to pedestrians must have at least one 20-ampere branch circuit dedicated to sign or outline lighting. This circuit must be installed at an accessible location for the sign.

• Article 600.6 — Disconnects: Each sign or outline lighting system must have an individual disconnect that simultaneously opens all ungrounded conductors. The disconnect must be within sight of the sign, or be capable of being locked in the open position. "Within sight" means visible and within 50 feet.

Key Concepts

Article 430 governs all aspects of motors, motor circuits, and controllers under the NEC 2020.

Branch-Circuit Conductor Sizing (430.22): Conductors supplying a single motor in continuous duty must have an ampacity of not less than 125% of the motor's full-load current (FLC), as determined by 430.6(A)(1) — not the nameplate, but the NEC tables.

Determining FLC (430.6): Always use NEC Tables 430.247 (DC), 430.248 (single-phase AC), 430.249 (2-phase AC), or 430.250 (3-phase AC) — not the motor nameplate — when sizing conductors and branch-circuit protection. The nameplate is used for overload protection sizing.

Article 402 – Fixture Wires

Fixture wires are governed by Article 402 and must comply with its requirements as well as any other applicable NEC articles. For luminaire applications specifically, Article 410 applies.

• Minimum size: Fixture wire shall not be smaller than 18 AWG (402.6).
• Voltage rating: All fixture wire types listed in Table 402.3 are suitable for 600 volts, nominal, unless otherwise specified (402.3). Exceptions include KF-1 and KFF-1, which are limited to 300 volts.
• Ampacity: Determined by Table 402.5. No conductor shall be used where its operating temperature exceeds the rating specified in Table 402.3 for its insulation type (402.5).
• Types must be listed: Fixture wires must be of a type…

Virginia Journeyman Electrician Exam | Article 411 NEC 2020

Key Concepts

Article 411 governs low-voltage lighting systems operating at no more than 30 volts AC or 60 volts DC. Where wet contact is likely, limits drop to 15 volts AC or 30 volts DC.

System Components (411.3): Every low-voltage lighting system must consist of three elements, all identified for the use: - An isolating power supply - Low-voltage luminaires - Associated equipment - Output circuits of the power supply are rated 25 amperes maximum under all load conditions

Key Concepts

Communication systems on the Virginia Journeyman exam draw primarily from NEC Article 725 (Class 1, 2, and 3 Remote-Control, Signaling, and Power-Limited Circuits) and NEC Article 800 (Communications Circuits).

Circuit Classifications: - Class 1 circuits: Higher power/voltage, must follow most standard wiring methods. Remote-control circuits for safety-control equipment are always Class 1 (per §725.31). - Class 2 circuits: Power-limited, lower voltage/current — considered inherently safe due to energy limitations. - Class 3 circuits: Similar to Class 2 but allow higher voltage (up to 150V); require more protection. - PLTC (Power-Limited Tray Cable): Used in cable trays per Article 392.

Key Concepts

Fire alarm and detection systems fall under Article 760 of the NEC 2020, which governs Fire Alarm Systems — circuits and equipment for the detection of fire, smoke, and products of combustion, or for signaling related to these conditions.

Key distinctions:

• Non-Power-Limited Fire Alarm (NPLFA) circuits operate similarly to Class 1 circuits — they use standard wiring methods and have higher voltage/power capabilities. Conductors must be a minimum of 14 AWG for branch circuits and 18 AWG for other wiring.
• Power-Limited Fire Alarm (PLFA) circuits operate under strict power limitations (analogous to Class 2/Class 3 circuits). These use listed cable types such as FPLP (plenum), FPLR (riser), and FPL (general purpose).

Key Concepts

Lockout/Tagout (LOTO) Program — Article 120

Every employer must establish, document, and implement a LOTO program (120.2(A)). The program applies to fixed, permanently installed, temporarily installed, and portable equipment — not just hardwired systems.

Who Must Be Involved: Every person who could be exposed directly or indirectly to a source of electrical energy must be involved in the LOTO procedure (120.3(A)). This includes, for example, a mechanic working on a coupling attached to a motor — not just the electrician working on the circuit.

Control Devices vs. Disconnecting Means (120.3(E)): Locks and tags shall be installed only on circuit disconnecting means. Push-buttons, selector switches, and other control devices cannot serve as the primary isolating device.
