NH Journeyman Electrician flashcards

31 cards. Read the term and the definition here. The deck at the top of this page is optional.

Branch circuit definition

The circuit conductors between the final overcurrent device protecting the circuit and the outlet or outlets served, per Article 100 of the National Electrical Code.

Feeder definition

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.

Continuous load rule

A load operating at maximum current for three hours or more must be calculated at 125 percent of its ampere rating for branch-circuit conductors and overcurrent protection.

Standard breaker sizes

Table 240.6(A) lists 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000 and 1200 amperes.

Dwelling general lighting load

Three volt-amperes per square foot of floor area for dwellings, calculated under Article 220, then reduced by the demand factors in Table 220.42.

Small appliance circuits

Two or more 20-ampere small-appliance branch circuits are required for kitchen, pantry, and dining areas, each calculated at 1500 volt-amperes in the dwelling load calculation.

Receptacle spacing rule

In dwellings, no point along the floor line may be more than six feet from a receptacle, and any wall space two feet or wider requires a receptacle.

Countertop receptacle rule

Kitchen and similar countertop receptacles must be installed so that no point along the countertop wall line is more than 24 inches from a receptacle outlet.

GFCI required locations

Ground-fault circuit-interrupter protection is required in bathrooms, garages, outdoors, kitchens, laundry areas, unfinished basements, and within six feet of sinks, among other locations.

AFCI protection

Arc-fault circuit-interrupter protection is required for dwelling-unit branch circuits supplying outlets in bedrooms, living rooms, kitchens, laundry areas, and similar rooms.

Working space clearances

A clear space 30 inches wide, 36 inches deep, and 6.5 feet high must be maintained in front of electrical equipment, with greater depth for higher voltages.

Ampacity adjustment factors

Table 310.16 ampacities are adjusted for ambient temperature and corrected when more than three current-carrying conductors are installed in a raceway or cable.

Grounding electrode conductor sizing

The grounding electrode conductor is sized from Table 250.66 based on the size of the largest service-entrance conductor, not on the load calculation.

Equipment grounding conductor sizing

Equipment grounding conductors are sized from Table 250.122 based on the rating of the overcurrent device protecting the circuit.

Box fill calculation

Conductor volume is counted per Table 314.16(B); all equipment grounds count as one, clamps and support fittings count, and the total must not exceed box volume.

NM cable support

Nonmetallic-sheathed cable must be secured within 12 inches of boxes and at intervals not exceeding 4.5 feet along runs, per Article 334.

Terminal torque requirement

Terminals and lugs must be tightened to the torque value marked by the manufacturer using a calibrated tool; loose connections cause overheating and fail inspection.

RSA 319-C purpose

New Hampshire statute establishing the Electricians' Board and the licensing, examination, discipline, and renewal framework for master, journeyman, and apprentice electricians.

Master electrician scope

A licensed master electrician may supervise electrical work, hold the license for an electrical contracting business, and direct journeymen and apprentices.

Journeyman experience requirement

Applicants must document years of supervised field experience verified by employers, with specific hours and documentation set by the board's administrative rules.

Apprentice supervision

Apprentices must work under supervision of a licensed master or journeyman and be enrolled in or complete an approved related-instruction program as the rules require.

License renewal education

Renewal on the board's cycle requires continuing education hours in code and related electrical subjects, earned through board-approved course providers.

Board disciplinary authority

The board may deny, suspend, or revoke a license or impose fines for incompetence, negligence, code violations, fraud, or working outside the license scope.

Unlicensed practice prohibition

A person may not perform or advertise electrical work requiring a license without holding the appropriate license class issued by the state board.

Adopted code standard

The board adopts a specific edition of the National Electrical Code as the standard for workmanship and examination content, and enforces it through discipline.

Experience verification forms

Administrative rules specify the employer attestation forms, hour thresholds, and deadlines an applicant submits to prove supervised experience before examination.

Examination eligibility

Rules set the board-approved competency exam, the adopted code edition tested, the passing score, and the period during which an approved application remains valid.

Supervision ratio rules

Board rules distinguish direct on-site supervision from indirect supervision and limit how many apprentices one licensed electrician may supervise.

Local permit and inspection

The authority having jurisdiction issues permits and inspects work; concealed work must be inspected before covering, and larger projects may require plan review.

Continuing education approval

Course providers must obtain board approval and keep attendance records; licensees may be required to produce proof of completed approved hours at renewal.

Conduit support intervals

Raceways must be supported within three feet of boxes and at intervals set by the applicable Article 3xx table, based on raceway type and size.
