Week 1

Overhead Distribution Construction and Maintenance

  • Map the overhead distribution system from substation to customer service drop, naming each major component (pole, crossarm, insulator, conductor, cutout, arrester, transformer, guy) and stating its function in one sentence.

  • Explain the purpose and minimum limits of approach for each voltage class in your jurisdiction, and list the conditions that require a switching or work permit before climbing or using an aerial device.

  • Calculate sag and tension relationships for a given span and conductor type using the ruling span method, and state how temperature and ice/wind loading change the result.

Week 2

Overhead Distribution Construction and Maintenance & Rigging, Aerial Devices, and Specialty Equipment

  • Demonstrate the correct selection, inspection, and rejection criteria for rigging hardware (slings, shackles, blocks, synthetic rope) used to set poles and string conductors, including how to read a capacity tag and account for sling angle.

  • Calculate the load on each leg of a bridle or pole-setting rigging arrangement and compare it to the working load limit of every component in the system.

  • Describe the pre-use inspection and setup of an aerial device (bucket truck): outrigger placement, ground condition checks, dielectric test date, upper/lower controls, and emergency lowering procedure.

  • Explain how to perform a pole-top rescue of an incapacitated worker using the aerial device and handline, and list the steps in order.

  • List the factors that determine whether a pole can be climbed safely (pole condition, guying, adjacent circuits, weather) and the tests used to confirm stability.

Your checkpoint

A rigging and aerial-device pre-job plan for one simulated pole-replacement job, showing each lift, the hardware selected with its working load limit, the calculated load, and the rescue plan.

Week 3

Live-Line (Energized) Work and Rubber Glove Procedures

  • Explain the rubber glove work method: minimum approach distances, glove class and testing interval, leather protector use, and the insulating barriers required for the specific task.

  • Describe how to establish and maintain an equipotential zone while working energized, including bonding of conductive components and the order of making and breaking connections.

  • Identify the limits of rubber glove work (voltage class, weather, structure type) and the situations that require de-energizing, grounding, or another work method instead.

  • Walk through a live-line task such as changing a cutout or installing a line hose, stating each step, the tool used, and the safety check performed before contact.

  • List the emergency response steps for a contact or flash event on an energized line, including how to free a victim safely and when to begin CPR or AED use.

Your checkpoint

A written rubber-glove procedure for one energized task, with a step-by-step sequence, the minimum approach distance for the voltage, and the barrier and bonding plan.

Week 4

Live-Line (Energized) Work and Rubber Glove Procedures & Occupational Skills and Safety

  • Apply the hierarchy of controls to a live-line job hazard analysis: identify the hazard, rank the controls (elimination, substitution, engineering, administrative, PPE), and justify why live-line work was chosen over de-energizing.

  • Demonstrate the lockout/tagout and switching procedure for de-energizing a circuit, including verification of the open point, test-before-touch, and application of personal protective grounds.

  • Describe the correct use, inspection, and storage of personal protective equipment for live-line work: rubber gloves and sleeves, insulating blankets, hard hat, arc-rated clothing, and face shield.

  • Explain the requirements for a competent person to inspect and reject insulating tools and rubber goods, including the air test, visual check, and record of test date.

  • Identify the reporting and investigation steps after a near miss or incident on an energized job, and the information that must be captured.

Your checkpoint

A completed job hazard analysis and switching/grounding plan for one de-energized job and one energized job, showing the controls selected and the PPE required for each.

Week 5

Underground Distribution Construction and Maintenance

  • Describe the underground distribution system from the riser or pad-mounted transformer to the customer meter, naming each component (cable, elbow, splice, pull box, vault, duct, grounding) and its function.

  • Explain cable pulling setup and calculations: pulling tension limits, sidewall pressure, lubricant use, and the checks performed before and during a pull.

  • Describe termination and splicing steps for a shielded underground cable, including cable preparation, stress cone formation, and the tests performed after termination.

  • Explain fault locating in underground cable using a thumper or time-domain reflectometer, and interpret a simple TDR trace to estimate fault distance.

  • List the safety requirements for entering and working in an underground vault or manhole: atmospheric testing, ventilation, confined-space entry procedure, and rescue readiness.

Your checkpoint

An underground cable installation and termination checklist covering pulling limits, splicing steps, post-installation tests, and vault entry safety.

Week 6

Transformers, Switching, and Voltage Control & Electrical Theory and Distribution System Fundamentals

  • Explain the operation and connection of distribution transformers: delta-wye and wye-wye bank connections, polarity, and how to verify phasing before paralleling.

  • Calculate transformer bank capacity, load division among units, and the effect of a single-phase outage in a three-phase bank.

  • Describe voltage control methods on a distribution feeder: tap changers, voltage regulators, capacitors, and line drop compensation, and state when each is used.

  • Explain switching procedures for isolating and restoring a transformer or feeder section, including the order of operations and the checks that prevent backfeed.

  • Apply Ohm's law and three-phase power relationships to calculate current, voltage drop, and power factor correction for a given feeder load.

Week 7

Troubleshooting, Fault Location, and Service Restoration & Electrical Theory and Distribution System Fundamentals

  • Describe the systematic troubleshooting sequence for a customer outage: verify the report, check the service, isolate the section, and confirm restoration, stating the test performed at each step.

  • Interpret common fault indications (blown cutout, recloser operation, low voltage, partial outage) and match each to the likely cause and the next diagnostic step.
