31 cards. Read the term and the definition here. The deck at the top of this page is optional.
- NM Electrical Bureau authority
- The Electrical Bureau of the New Mexico Regulation and Licensing Department licenses electricians and enforces the adopted electrical code; local authorities having jurisdiction may add amendments and permit requirements.
- Journeyman electrician scope
- A licensed journeyman may perform electrical installations while employed by or under the supervision of a licensed contractor or master; the license does not authorize independent contracting or bidding.
- Master electrician role
- A master electrician may contract for electrical work and serve as qualifying party for an electrical contractor; the master carries responsibility for code compliance of work performed under that license.
- Qualifying party requirement
- An electrical contractor license requires a designated qualifying party who holds the appropriate master or journeyman credential and who is responsible for the contractor's code-compliant work.
- Experience documentation
- Applicants must submit verifiable hours of practical experience under licensed supervision on forms accepted by the Bureau; falsified hours are grounds for denial or discipline.
- Continuing education renewal
- License renewal requires continuing education hours in categories set by the Bureau per renewal cycle; licensees should retain completion certificates because the Bureau audits compliance.
- Permit and inspection rule
- Most electrical installations require a permit before work begins and inspection before concealment; the authority having jurisdiction may require the licensed electrician's signature on the application.
- Adopted code edition
- New Mexico adopts an edition of the NEC statewide through the Construction Industries Commission; always confirm the edition and local amendments in effect for the project jurisdiction.
- Unlicensed practice penalties
- Contracting without a license, supervising beyond authority, or falsifying experience can result in fines, suspension, or revocation by the Electrical Bureau after disciplinary proceedings.
- License lapse reinstatement
- A lapsed license may be reinstated under Bureau rule with late fees and proof of continuing education; practicing on a lapsed license is unlicensed activity subject to discipline.
- GFCI purpose
- A ground-fault circuit interrupter detects small line-to-ground current imbalances and opens the circuit quickly to prevent electric shock to people.
- AFCI purpose
- An arc-fault circuit interrupter detects characteristic arcing signatures in branch circuit conductors and opens the circuit to reduce fire ignition risk.
- GFCI dwelling locations
- NEC 210.8 requires GFCI protection in dwelling bathrooms, garages, outdoors, kitchens, laundry areas, basements, and other listed locations for 125- to 250-volt receptacles.
- AFCI dwelling circuits
- NEC 210.12 requires arc-fault protection for most 120-volt, 15- and 20-ampere branch circuits supplying outlets in dwelling units, with limited exceptions.
- Equipment grounding conductor
- The equipment grounding conductor provides a low-impedance fault path back to the source so overcurrent devices open; its size follows NEC Table 250.122 based on device rating.
- Bonding versus grounding
- Bonding connects metallic parts to keep them at equal potential, while grounding connects the system to earth; bonding is what clears faults, not the earth connection alone.
- Working clearance depth
- NEC 110.26 requires working space in front of equipment based on voltage and condition; minimum depth is 3 feet and increases with voltage and exposed live parts.
- Next-size-up rule
- NEC 240.4(B) permits rounding up to the next standard overcurrent rating when conductor ampacity does not match a standard size, subject to strict conditions.
- Lockout tagout
- Before servicing equipment, isolate all energy sources, apply locks and tags, and verify the absence of voltage with a tested meter to prevent unexpected energization.
- Arc-rated PPE selection
- Arc-rated clothing and voltage-rated gloves are chosen from an incident-energy analysis or the hazard tables, matched to the task and equipment voltage.
- Ground-fault protection equipment
- GFPE for large services and feeders senses lower-level ground faults and opens the circuit to limit equipment damage; it is distinct from personnel GFCI protection.
- Receptacle outlet defined
- An outlet is any point on the wiring system where current is taken to supply utilization equipment; a receptacle is a specific type of outlet device.
- Overcurrent device defined
- An overcurrent device, such as a fuse or circuit breaker, automatically opens a circuit when current exceeds a safe value, protecting conductors from overheating.
- Service disconnect location
- The service disconnecting means must be installed at a readily accessible location nearest the point of entrance of service conductors, per NEC 230.70.
- Bonding at service
- At the service, the grounded conductor is bonded to the equipment grounding conductor and enclosure; downstream, neutral and ground must remain separate on the load side.
- Temporary power safety
- Temporary wiring must be protected from damage, supported properly, and supplied through GFCI protection for personnel on construction sites per NEC Article 590.
- Voltage testing practice
- Verify a voltage tester on a known live source before and after checking a circuit; a tester that fails either check cannot confirm the circuit is de-energized.
- Conductor ampacity basis
- Conductor ampacity comes from the applicable NEC tables, adjusted for ambient temperature and number of current-carrying conductors in a raceway or cable.
- Class A GFCI threshold
- A Class A GFCI trips at a ground-fault current of 4 to 6 milliamperes, a level intended to protect people from ventricular fibrillation risk.
- Accessible and readily accessible
- Accessible means reachable without climbing over or removing obstacles; readily accessible means reachable quickly without tools, stairs, ladders, or portable means.
- Arc flash boundary
- The arc flash boundary is the distance at which incident energy equals 1.2 calories per square centimeter, the threshold for second-degree burn injury.
