QEW Commercial Electrical Safety and Systems Training

QEW Commercial Electrical Safety and Systems Training

Commercial HVAC work involves higher voltages, three-phase power, and coordination with other trades on energized systems. This 34-hour online course provides electrical safety training for technicians working in commercial and industrial environments.

Why commercial HVAC
technicians need QEW
training

Commercial HVAC technicians coordinate lockout/tagout with facility managers, conduct safety briefings with electrical contractors before opening panels, and follow site-specific protocols that vary by building.

At higher voltages, arc flash boundaries, PPE requirements, and approach distances become critical safety considerations. OSHA and NFPA 70E expect workers on commercial jobs to understand these hazards before they encounter energized equipment.

What QEW Commercial Training covers

This program teaches HVAC technicians to work safely around energized equipment in commercial and industrial settings. By the end of this program, technicians will learn to:

  • Identify electrical hazards and apply OSHA and NFPA 70E (2024) safety standards for commercial environments

  • Select and use appropriate PPE for various voltage levels and tasks

  • Perform lockout/tagout and verification procedures when coordinating with facility teams

  • Conduct job briefings and maintain required approach distances

  • Understand electrical theory, DC/AC circuits, three-phase power, Ohm’s and Kirchhoff’s Laws

  • Troubleshoot motors, drives, and control circuits on commercial equipment 

  • Follow essential wiring and installation principles based on NEC requirements

  • Read electrical drawings, engineering prints, and building schematics

QEW Commercial Training FAQ

Residential QEW (30 hours) covers residential and light commercial systems — single-phase equipment, lower voltages, and straightforward electrical configurations.

Commercial QEW (34 hours) includes all that content plus heavy commercial applications — three-phase power, higher voltage systems, and the coordination requirements for working in commercial and industrial facilities.

If your techs primarily work on houses and small businesses, choose Residential. If they handle larger commercial buildings and industrial sites, choose Commercial.

The employer makes that determination after technicians complete training and demonstrate hands-on competency, according to OSHA standards. This course provides the theory-based training portion of that requirement.

The training is 34 hours of online content. Technicians have 180 days to complete it.

OSHA and NFPA 70E recommend retraining every three years minimum, or sooner if job responsibilities change.

No, this is online theory-based training. Hands-on practice and competency verification happen in your workplace.

NFPA 70E is the Standard for Electrical Safety in the Workplace. It establishes practices for protecting workers from electrical shock, arc flash, and arc blast hazards when working on or near energized equipment.

Technicians receive an ACCA certificate documenting completion of the training.

Yes, the course covers residential, light commercial, and heavy commercial applications. The additional four hours beyond the Residential course focus specifically on larger commercial and industrial systems.

IMPORTANT | Per OSHA Qualified Electrical Worker (1910.332–333) standards, it is the employer who may deem their worker as trained to be a QEW. ACCA cannot make this designation for you.

The computer-based QEW training offered by ACCA is meant to be part of an employer's QEW program for an HVAC technician. The training is intended to supplement an HVAC employer’s on-the-job QEW training.
