Medium-Voltage Fundamentals & NFPA 70E Qualified-Person Path
This course establishes the electrical safety foundation for all subsequent medium-voltage (MV) coursework in the program. Students learn MV system fundamentals -- three-phase power, transformation, fault current, and grounding at 601V to 38kV class -- and the NFPA 70E framework for shock and arc-flash protection: approach boundaries, incident energy, PPE categories, and the qualified-person determination. Students perform arc-flash risk assessment using published tables, select PPE by category, and execute lockout/tagout and voltage verification procedures under direct supervision on de-energized training equipment only; no student performs energized MV work in this course. OSHA 30 Construction is embedded as a graduation requirement, and course completion is a prerequisite condition -- not a guarantee -- of employer or state qualified-person designation, which remains an employer determination under OSHA 1910.269 and NFPA 70E. This course is the gateway to every other EMV course in the sequence and cannot be waived by prior low-voltage experience alone.
What you'll be able to do
- Classify a given electrical task's shock hazard using the NFPA 70E approach boundary table for the system voltage. Safety-critical
- Determine the arc-flash PPE category for a given piece of equipment using the NFPA 70E incident-energy or PPE-category table method. Safety-critical
- Select and don arc-rated PPE matching the required category for a stated task. Safety-critical
- Execute a lockout/tagout procedure on a de-energized MV training cabinet and verify absence of voltage before any barrier is removed. Safety-critical
- Perform an arc-flash risk assessment for a stated MV task and document the likelihood and severity determination. Safety-critical
- Distinguish the criteria that make a worker a 'qualified person' under NFPA 70E and identify who holds the authority to make that designation. Safety-critical
- Calculate available fault current at a point in a simplified MV distribution one-line diagram.
- Explain MV grounding system configurations (solidly grounded, high-resistance, ungrounded) and their effect on fault behavior.
- Verify absence of voltage on a de-energized MV cabinet using a rated proximity or contact voltage detector under the direct observation of a licensed qualified person. Safety-critical
- Complete the OSHA 30 Construction curriculum modules relevant to electrical safety and pass the embedded assessment.
- Document an electrically safe work condition (ESWC) log entry for a completed lockout/verification sequence. Safety-critical
- Identify the boundary conditions under which energized MV work is prohibited versus permitted only with written justification. Safety-critical
