New Mexico Low Voltage Practice study plan

Define the core electrical quantities (voltage, current, resistance, power, impedance) and state the unit and symbol for each from memory

Apply Ohm's law and the power equation to at least 20 practice calculations involving resistive loads and mixed series-parallel circuits

Explain the difference between AC and DC circuit behavior, including how inductance and capacitance affect current in low voltage circuits

Distinguish grounded, grounding, and bonding conductors and describe the fault-current path that opens an overcurrent device

Trace the structure of NEC Article 100 definitions and identify the terms that govern low voltage scope, such as listed, labeled, and identified

Determine when a circuit falls under Class 2 or Class 3 power-limited requirements versus Chapter 3 wiring methods

Calculate voltage drop for a 24 VDC and a 70 V line run and compare results against commonly applied limits

Summarize how the New Mexico Electrical Code adopts and amends the NEC and note where local authority overrides apply

Compare the operating principles, typical voltages, and use cases for fire alarm, access control, CCTV, intrusion, audio, and data systems

Identify the power source, load, and signaling path in each of six low voltage system types

Explain supervised versus unsupervised circuits and why supervision matters for life safety systems

Select an appropriate conductor type and gauge for a given low voltage load and distance, showing the calculation

Match Chapter 3 wiring methods (raceway, cable, and free-air) to low voltage applications and state one installation constraint for each

Describe support, securing, and protection-from-physical-damage requirements for low voltage cable runs

Explain separation requirements between power-limited and electric light and power conductors in raceways and boxes

Identify listing and marking requirements for cable, raceway, and fittings used in low voltage work

Locate and apply the code articles governing fire alarm, security, and communications systems, including their power-limited and pathway provisions

Explain pathway survivability concepts and how they affect cable routing decisions in a fire alarm design

Describe grounding and bonding requirements for communications and antenna systems at the point of entry

Identify the inspection points a New Mexico inspector is most likely to check on a low voltage rough-in

Demonstrate safe lockout and verification procedure for de-energizing a circuit before work, listing the steps in order

Select the correct test instrument for continuity, voltage, resistance, and insulation checks and explain the limits of each

Interpret a multimeter reading for an open circuit, a short, and a grounded conductor and state the likely fault

Identify personal protective equipment and safe practices for work near energized equipment and in confined spaces

Outline the New Mexico licensing pathway for low voltage contractors, including application, examination, and renewal steps

Explain the difference between licensing, permitting, and inspection responsibilities on a low voltage project

Draft a scope of work and a change-order clause for a small commercial low voltage installation

Estimate labor hours and material cost for a 20-device installation and state the assumptions used

Review every domain using the deliverables from weeks 1 through 7 and correct all previously missed items

Complete a timed 60-question mixed practice set covering all seven domains and score each domain separately

Re-study the two weakest domains until practice accuracy exceeds 80 percent in each

Write a final one-page summary of the code articles and calculations most likely to appear on the exam
