CT Electrician · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Wiring and Protection

  • Calculate branch-circuit, feeder, and service loads for one dwelling unit and one small commercial occupancy using demand factors

  • Size overcurrent protective devices and conductors for 15 A through 200 A circuits directly from the ampacity and standard-rating tables

  • Distinguish grounding from bonding and list five field conditions where each is required

  • Explain the required locations and ratings for GFCI and AFCI protection across dwelling, kitchen, bath, garage, and outdoor circuits

Your checkpoint

Closed-book 40-question Domain 2 quiz scored at 80% or better, with every missed item rewritten as a corrected rule statement in a personal error log

Week 2

Wiring and Protection & Wiring Methods and Materials

  • Apply ambient-temperature correction and conduit-fill adjustment factors to 10 conductor ampacity problems

  • Select an appropriate wiring method (NM-B, MC, AC, EMT, IMC, PVC, LFMC) for 12 described installations and cite the governing article for each

  • Compute box fill for 8 outlet/switch/junction layouts and conduit fill for 4 raceway runs

  • Produce a three-circuit residential layout showing overcurrent device, conductor size, and wiring method for each circuit

Your checkpoint

Completed load-calculation worksheet plus a 12-row wiring-method decision table with Code citations, self-graded against the Code

Week 3

Wiring Methods and Materials & Equipment for General Use

  • Verify support, securing, bending-radius, and burial-depth requirements for six different raceway and cable types

  • Size branch-circuit conductors and overload protection for six motor installations using nameplate and table data

  • Select and locate receptacles, switches, luminaires, and panelboards for three sample room layouts

  • Check disconnect, working-clearance, and mounting-height requirements for switchboards, panelboards, and HVAC equipment

Your checkpoint

Hand-drawn single-line diagram of a small service with panel schedule, motor branch circuits, and equipment disconnects, checked against at least 10 Code rules

Week 4

General Electrical Knowledge and Electrical Theory & Equipment for General Use

  • Solve 20 Ohm's-law and power problems covering series, parallel, and combination circuits

  • Compute current, voltage, and power in balanced three-phase and single-phase systems including power factor

  • Calculate voltage drop on three branch circuits and select an upsized conductor that meets a 3% limit

  • Explain transformer turns ratio, primary/secondary current relationships, and grounding requirements for a dry-type transformer

Your checkpoint

Timed 30-question quiz covering theory plus general-use equipment, scored at 80% or better, with worked solutions for all missed items

Week 5

Business Management, Estimating, and Plan Reading & Special Occupancies

  • Perform a quantity takeoff of panels, devices, raceway, and conductors from a two-sheet residential plan set

  • Build a material-and-labor estimate with markup and produce a bid summary sheet

  • Identify plan symbols, scale, and specification sections on a commercial drawing set

  • Classify 10 hazardous-location and special-occupancy scenarios by class, division or zone, and required wiring method

Your checkpoint

Complete takeoff and one-page bid summary for the sample plan set, plus a scored classification worksheet for hazardous and special occupancies

Week 6

Special Equipment & Special Conditions

  • Apply sizing and disconnect rules to generators, transfer switches, welders, and pool equipment for eight practice scenarios

  • Determine requirements for emergency, legally required standby, and optional standby systems and distinguish where each applies

  • List installation restrictions for sign, crane, elevator, and electric-vehicle supply equipment circuits

  • State the additional requirements that apply above 1000 V and in interconnected power production systems

Your checkpoint

One-page comparison matrix of special equipment and special conditions showing governing article, key sizing rule, and one common exam trap per row

Week 7

Communication Systems & Safety Practices and Connecticut Electrical Regulations

  • Outline the Chapter 8 requirements for communications, CATV, and network-powered broadband circuits including grounding and bonding of cable and protectors

  • Differentiate permitted and prohibited cable substitutions between communications, Class 2/3, and power circuits

  • Determine shock and arc-flash approach boundaries and select PPE for three described tasks

  • Summarize Connecticut licensing, permit, and inspection sequence and list three adopted state amendments to the national Code

Your checkpoint

Two-page quick-reference sheet: one page on communications and signaling rules, one page on Connecticut licensing, permits, inspections, and safety boundaries

Week 8

Wiring and Protection & Wiring Methods and Materials & Equipment for General Use & General Electrical Knowledge and Electrical Theory & Business Management, Estimating, and Plan Reading & Special Occupancies & Special Equipment & Special Conditions & Communication Systems & Safety Practices and Connecticut Electrical Regulations

  • Take two full-length timed 80-question practice exams under test-day conditions

  • Rank the ten domains by practice-exam accuracy and re-drill the three weakest

  • Review the personal error log and restate each corrected rule from memory

  • Practice Code index lookups until 20 unfamiliar references are located in under 12 minutes

Your checkpoint

Practice-exam score report showing both attempts above 80% overall with no domain below 70%, plus a finalized one-page final-review sheet

Milestones

Week 2: Score 80% or better on a 30-question mixed Domain 2 and 3 quiz and correctly cite the governing article for at least 9 of 12 wiring-method scenarios

Week 4: Complete all branch-circuit, feeder, and voltage-drop calculations in the sample project with no arithmetic errors and pass the Week 4 theory and equipment quiz at 80%

Week 6: Deliver a takeoff and bid summary within 10% of the instructor benchmark and score 80% or better on the special-occupancy classification worksheet

Week 8: Two timed full-length practice exams both scored above 80% overall with no individual domain below 70%, and all error-log entries restated correctly
