Electrical Performance Req. AHA (Activity Hazard Analysis / Job Hazard Analysis)
Updated 2026-06-23
A Electrical Performance Req. AHA (Activity Hazard Analysis / Job Hazard Analysis) is the plan that keeps the crew performing electrical performance testing safe from energization and arc flash, from the stored energy and testing, and from unexpected energization. Electrical performance testing verifies that the electrical systems meet their performance requirements — combining the energization and live-electrical/arc-flash hazard, the stored-energy and testing hazard, and the unexpected-energization and coordination hazard. This guide walks through building a Electrical Performance Req. AHA that names the energization/live-electrical-and-arc-flash, stored-energy/testing, and unexpected-energization/coordination hazards and assigns the energization, stored- energy, and coordination controls that hold up in the field.
Why electrical performance req. needs its own AHA
Electrical performance testing verifies that the electrical systems — switchgear, distribution, transformers, generators, panels, and power systems — meet their performance and acceptance requirements, energizing and testing the systems to confirm operation, protection, and performance. The defining feature is that the testing involves energizing and working with live electrical systems (including high-energy systems like switchgear and transformers), bringing the shock and — critically — arc-flash hazards, plus the stored energy in electrical systems and the risk of unexpected energization. The hazards combine the energization and live-electrical/arc- flash (energizing and testing the electrical systems — the shock and arc-flash hazards of live electrical work, especially on high-energy systems (switchgear, transformers) where arc flash is a severe hazard), the stored-energy and testing (electrical systems store energy (capacitors, batteries, transformers) and the testing (insulation testing, high-potential testing) applies dangerous test voltages — the stored-energy and test-voltage hazards), the unexpected-energization and coordination (energizing systems creates the hazard of unexpected energization for others working on the systems — coordination of energization is critical), and the electrical work. The energization/live-electrical/arc-flash and the unexpected-energization/coordination justify a dedicated AHA.
Breaking electrical performance req. into steps
The steps for a Electrical Performance Req. AHA follow the testing:
- Plan the test and coordinate the energization
- Verify systems and personnel are ready to energize
- Perform the electrical testing (insulation, hi-pot, etc.)
- Energize the systems (coordinated, controlled)
- Test the energized systems (arc-flash PPE, qualified)
- Manage the arc-flash, stored-energy, and energization hazards
- Verify the performance
- Return to normal state
Each step carries a hazard, and the energization/live-electrical/arc-flash, the stored-energy/testing, and the unexpected-energization/coordination are where the most significant risks concentrate.
The hazards step by step
Energization and live-electrical/arc-flash
Energizing and testing the electrical systems — the shock and arc-flash hazards of live electrical work, especially on high-energy systems (switchgear, transformers) where arc flash is a severe hazard. The controls are qualified electrical workers, arc-flash and shock PPE (rated for the incident energy), NFPA 70E-compliant work practices (approach boundaries, arc-flash boundaries, energized-work permits), de-energizing where possible, and the energization/arc-flash controls. The energization/live-electrical/arc-flash is the primary defining hazard — arc flash on high-energy systems is severe. (These follow the arc-flash/electrical-safety fundamentals.)
Stored-energy and testing
Electrical systems store energy (capacitors, batteries, transformers) and the testing (insulation testing, high-potential testing) applies dangerous test voltages — the stored-energy and test-voltage hazards. The controls are discharging/grounding stored energy before contact (capacitors, cables hold charge), managing the test voltages (high-potential and insulation testing apply lethal voltages — controlled testing, exclusion, grounding after), qualified testing personnel, and the stored-energy/testing controls. The stored-energy/testing is a defining hazard — stored energy and test voltages are lethal. (These follow the stored-energy fundamentals.)
Unexpected-energization and coordination
Energizing systems creates the hazard of unexpected energization for others working on the systems — coordination of energization is critical. The controls are coordinating and communicating energization (so no one is working on a system that gets energized), LOTO where systems must stay de-energized, verifying no one is exposed before energizing, a controlled energization sequence, and the coordination controls. The unexpected-energization/coordination is a defining hazard — energizing a system endangers anyone working on it. (These follow the energization-coordination fundamentals.)
Electrical work
The electrical work (the general electrical work on the systems) carries the electrical hazard. The controls are qualified electrical work, LOTO/energy control, and the electrical controls. (These follow the electrical-safety fundamentals.)

| Test energized | Arc flash | Arc-flash PPE, qualified workers, 70E practices | NFPA 70E |
| Return to normal | Energization | Return to normal state | project |
Arc-flash/energization safety and energization coordination
A Electrical Performance Req. AHA centers on arc-flash/energization safety and energization coordination. The arc-flash/energization safety addresses the live electrical and arc-flash hazards — controlled by qualified electrical workers, arc-flash and shock PPE rated for the incident energy, NFPA 70E-compliant work practices (approach and arc-flash boundaries, energized-work permits), and de-energizing where possible, since arc flash on high-energy systems is severe. The energization coordination addresses the unexpected-energization hazard — controlled by coordinating and communicating energization (so no one is working on a system that gets energized), LOTO where systems must stay de-energized, verifying no one is exposed before energizing, and a controlled energization sequence. And the stored energy gets discharge/grounding and test-voltage controls. An AHA built on arc-flash/energization safety and energization coordination, with stored-energy controls, addresses the hazards that define electrical performance testing.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, electrical performance testing is high-hazard work because it involves energizing and testing live electrical systems, including high-energy systems where arc flash is a severe and potentially fatal hazard. The energization and live-electrical/arc-flash hazard is the primary defining concern — energizing and testing the electrical systems means working with live electrical power, bringing the shock hazard and, critically, the arc-flash hazard, which is especially severe on high-energy systems like switchgear and transformers. An arc flash releases enormous energy (heat, pressure, and light) and can cause fatal burns and injuries, so on high-energy electrical systems it is one of the most severe hazards in construction. So qualified electrical workers, arc-flash and shock PPE rated for the incident energy, NFPA 70E-compliant work practices (approach boundaries, arc-flash boundaries, and energized-work permits), and de-energizing where possible are the controls. The arc-flash hazard is why energized electrical testing demands the full 70E discipline and rated PPE.
The unexpected-energization/coordination and the stored-energy/testing are the other defining hazards. On the projects I have run, electrical performance testing energizes systems, which creates a serious hazard for anyone else working on those systems: unexpected energization. If a system is energized while someone is working on it (because the energization was not coordinated or communicated), that person is exposed to the full electrical hazard without warning. So coordinating and communicating the energization (so no one is working on a system that gets energized), LOTO where systems must stay de-energized, verifying no one is exposed before energizing, and a controlled energization sequence are the controls. Energization coordination is a life-safety control, because energizing a system endangers everyone working on it. The stored-energy and testing hazard is that electrical systems store energy (capacitors, batteries, and transformers hold charge) and the testing itself (insulation testing and high-potential testing) applies lethal test voltages, so discharging and grounding stored energy before contact, managing the test voltages (controlled testing, exclusion, grounding after), and qualified testing personnel are the controls. Stored energy and test voltages are both lethal. The general electrical work rounds it out. The AHA built on arc-flash/energization safety and energization coordination is the one that protects the electrical-testing crew.
The bottom line
A Electrical Performance Req. AHA names the energization/live-electrical/arc-flash, the stored-energy/testing, and the unexpected-energization/coordination hazards with specific controls — qualified workers with arc-flash- rated PPE and NFPA 70E practices for the severe arc-flash hazard on high-energy systems, coordinated energization so no one is working on a system that gets energized, and discharge/grounding of stored energy with managed test voltages. The arc-flash/energization safety and the energization coordination are the defining concerns. The AHA that manages both is the one that protects the crew.
Frequently asked questions
Why is arc flash the primary hazard in electrical performance testing?
Energizing and testing the electrical systems means working with live electrical power, and the arc-flash hazard is especially severe on high-energy systems like switchgear and transformers — an arc flash releases enormous energy (heat, pressure, light) and can cause fatal burns and injuries, making it one of the most severe hazards in construction. Controls are qualified electrical workers, arc-flash and shock PPE rated for the incident energy, NFPA 70E-compliant work practices (approach and arc-flash boundaries, energized-work permits), de-energizing where possible, and the energization/arc-flash controls.
Why is unexpected energization a life-safety hazard?
Electrical performance testing energizes systems, so if a system is energized while someone is working on it (because the energization was not coordinated or communicated), that person is exposed to the full electrical hazard without warning. Controls are coordinating and communicating energization (so no one is working on a system that gets energized), LOTO where systems must stay de-energized, verifying no one is exposed before energizing, a controlled energization sequence, and the coordination controls.
What stored-energy and test-voltage hazards apply?
Electrical systems store energy (capacitors, batteries, and transformers hold charge), and the testing itself (insulation testing, high-potential testing) applies lethal test voltages. Controls are discharging/grounding stored energy before contact, managing the test voltages (controlled testing, exclusion, grounding after), qualified testing personnel, and the stored-energy/testing controls — stored energy and test voltages both being lethal.
What is electrical performance testing?
Electrical performance testing verifies that the electrical systems — switchgear, distribution, transformers, generators, panels, and power systems — meet their performance and acceptance requirements, energizing and testing the systems to confirm operation, protection, and performance. Because it involves energizing live systems (arc flash), stored energy and test voltages, and the risk of unexpected energization, those hazards apply.
