DC Electrician study plan

Define voltage, current, resistance, and power and state the unit for each without notes

Apply Ohm's law and the power wheel to solve 30 mixed DC circuit problems with at least 90% accuracy

Compute series and parallel equivalent resistance for 10 resistor networks, showing each step

Build a personal formula sheet limited to one page covering Ohm's law, power, and series/parallel rules

Locate and tabulate the code articles governing conductors, overcurrent protection, and grounding

Calculate voltage drop on single-phase and three-phase feeders using the standard circular-mil formulas

Size conductors for ampacity after applying adjustment and correction factors to a given load

Explain the difference between ampacity, overload, and short-circuit protection and where each applies

Interpret code tables for conductor properties and raceway fill from memory of their structure, not values

Complete 20 code-lookup drills under a 90-second-per-question time limit

Identify the wiring method permitted for a given occupancy and location class

Compute raceway fill percentage for mixed conductor sizes and compare against the allowed limit

Describe bending, support spacing, and box-fill requirements for common raceway types

Select the correct box size for a stated conductor count and device fill

Diagram three compliant raceway runs showing supports, boxes, and expansion points

Distinguish cable types by insulation, jacket, and permitted use location

List protection and support requirements for cable runs through framing, attics, and buried sections

Explain grounding and bonding requirements at service, panel, and device level

Trace a grounding electrode system from rod to panel and label each bonding jumper

Correct five intentionally noncompliant installation scenarios and cite the rule violated

Match overcurrent device types to their trip characteristics and intended applications

Size and select disconnects, receptacles, and switches for given load and environment conditions

Interpret motor nameplate data to derive branch-circuit and overload protection values

Explain enclosure and device ratings for wet, damp, and hazardous locations

Assemble a device selection table covering 15 common residential and light commercial loads

Wire a panel schedule for a mixed-load service and balance the phases

Verify AFCI and GFCI protection requirements by room and circuit type

Diagnose six fault scenarios such as open neutral, reversed polarity, and shared neutral

Describe testing procedures and instruments used to confirm each diagnosis

Calculate available fault current implications for selecting interrupting ratings

State lockout/tagout, approach boundary, and PPE requirements for common tasks

Summarize the licensing scope, renewal, and continuing education rules for the jurisdiction

Outline contract essentials including estimates, change orders, and lien notices

Identify the permit and inspection sequence for a typical residential project

Explain employer and worker responsibilities under occupational safety rules

Complete two full-length timed practice exams simulating test-day conditions

Review every missed question and write the underlying rule or formula for each

Re-drill the 20 weakest concepts until each is answered correctly twice in a row

Rehearse code navigation to find any cited article within 60 seconds

Finalize a one-page test-day reference card and logistics plan
