Basic Electricity for Line Workers

Course Description

ETP1101C – Basic Electricity for Line Workers is a 2-credit-hour, combined lecture/laboratory course in the Engineering Technologies > Energy Power Technology taxonomy of the Florida Statewide Course Numbering System. The course introduces students to the fundamental principles of electricity as applied to the electric utility distribution and transmission industry. Topics include DC and AC circuit theory, Ohm's Law, electrical measurements, magnetism, and transformer fundamentals — all framed within the context of line work safety and field practice. Approximately 40–50 percent of instructional time is hands-on laboratory activity. This course is commonly a foundational requirement within Florida college Electrical Lineworker Career Certificate programs and Electrical Distribution Technology associate degree pathways.

• Safety References: OSHA 29 CFR 1910.269 (Electric Power Generation, Transmission, and Distribution); NESC (ANSI C2); employer-issued job briefing and PPE guides.
• Software/Simulation: Circuit simulation software such as Multisim or similar tools may be used to model DC and AC circuits prior to hands-on lab work.

Career Pathways

Completion of ETP1101C provides the foundational electrical knowledge required to advance in the following career pathways within the Florida energy and utility sector:

• Apprentice / Trainee Line Worker — Entry-level field position with investor-owned utilities (e.g., Florida Power & Light / NextEra Energy, Duke Energy Florida, Tampa Electric / TECO), electric cooperatives, and municipal utilities.
• Groundman / Groundwoman — Crew-support role that requires demonstrated knowledge of electrical hazards and utility safety protocols.
• Electrical Distribution Technician — Technician-level role in overhead and underground distribution construction and maintenance.
• Substation Technician (entry pathway) — Foundational electrical theory from this course supports advancement into substation operations training.
• Utility Line Contractor (long-term) — Florida DBPR Utility Line Electrical Contractor license requires demonstrated knowledge of transmission and distribution electrical circuits; ETP1101C provides foundational preparation for the required state examination.

Students completing this course as part of the Electrical Lineworker Career Certificate may apply credits toward the Associate in Applied Science (A.A.S.) in Industrial Management Technology or Electrical Distribution Technology at participating Florida colleges. The electric utility industry is projected to see continued workforce growth, driven by aging grid infrastructure, storm hardening, and renewable energy integration across Florida.

Special Information

Certification Preparation

ETP1101C supports preparation for several industry-recognized credentials commonly earned through Florida Electrical Lineworker programs:

• NCCER Electrical Lineworker Level 1 & 2 — National Center for Construction Education and Research certification; recognized by utility employers nationwide and earned through programs approved by NCCER.
• OSHA 10-Hour Card (Construction / Utility) — Safety awareness certification required by many utility employers as a condition of hire; safety content in ETP1101C directly aligns with OSHA 10 topics.
• CPR / AED and First Aid — American Red Cross or equivalent certification; typically required in conjunction with lineworker coursework.
• Florida Utility Line Electrical Contractor Exam (DBPR) — The state licensing examination for Utility Line Electrical Contractors covers General Theory and Electrical Principles, Wiring and Protection, Utility Technical/Safety, and OSHA topics — all of which are introduced in ETP1101C.

Physical and Program Requirements

Students enrolled in programs containing ETP1101C should be aware that lineworker programs typically require candidates to be at least 18 years of age, possess a valid driver's license, and meet physical fitness standards (including ability to work at heights and in varying weather conditions). Some programs require completion of a mandatory orientation or boot camp prior to full enrollment. A Class A Commercial Driver's License (CDL) is a common program-level goal within the Electrical Lineworker Career Certificate.
