Electrical Termination JHA (Job Hazard Analysis / Activity Hazard Analysis)
Updated 2026-06-23
An Electrical Termination JHA (Job Hazard Analysis / Activity Hazard Analysis) is the plan that keeps the crew terminating electrical conductors from being shocked or caught in an arc flash, especially when the termination is at or near energized equipment. Electrical termination connects conductors to equipment, devices, and each other — landing wires at panels, switchgear, motors, and devices — where the shock and arc-flash hazards depend critically on whether the work is de-energized. This guide walks through building an Electrical Termination JHA that names the shock, arc-flash, and energized-work hazards and assigns the de-energization, verification, and arc-flash controls that hold up in the field.
Why electrical termination needs its own JHA
Electrical termination makes the connections that complete electrical circuits — landing conductors at panelboards, switchgear, motor control centers, transformers, motors, and devices, using lugs, terminals, connectors, and torque connections. The work is precise (proper connections, torque) and electrical. The hazards center entirely on the energy state. If the conductors and equipment are de-energized, the work is relatively low-hazard; if they are energized or near energized parts, the shock and arc-flash hazards are serious and potentially fatal. The arc-flash hazard is significant at panels, switchgear, and other equipment where fault energy is high. And terminations at existing or partially energized equipment, or where adjacent parts remain energized, are the higher hazard. The shock and arc-flash hazards, governed by the energy state, justify a dedicated JHA.
Breaking electrical termination into steps
The steps for an Electrical Termination JHA follow the termination:
- Identify the circuit, the equipment, and the energy state
- De-energize, lock out, and verify absence of voltage
- Establish energized-work controls only if de-energization is infeasible
- Prepare and land the conductors
- Torque the terminations to specification
- Verify the connections
- Re-energize under controlled conditions
- Test the circuit
Each step carries a hazard, and the energy-state verification and any energized work are where the most serious risks concentrate.
The hazards step by step
Shock from energized conductors
Terminating energized conductors, or conductors that are unexpectedly energized, exposes the worker to shock and electrocution. The controls are de-energizing and locking out the circuit before terminating, testing for absence of voltage at the point of work (verifying it is dead, with a tested meter), confirming the correct circuit is isolated, and not assuming a conductor is dead. The fundamental control is to work de-energized whenever possible, verified by testing. (These follow the electrical-work and LOTO fundamentals.)
Arc flash
Working at or near energized equipment (panels, switchgear, MCCs) where fault energy is high exposes the worker to arc flash — an explosive release of energy causing severe burns and injuries. The controls are de-energizing to eliminate the arc-flash hazard where possible, and where energized work near the equipment is unavoidable, the arc-flash analysis, boundaries, and PPE (arc-rated clothing, face protection) per the incident energy, plus the energized-work permit and qualified workers. The arc-flash hazard is highest at high-fault-energy equipment.
Energized work (when unavoidable)
Some terminations must be done energized or near energized parts (where de-energization is infeasible) — the higher hazard. The controls are the energized electrical work program: justification and a permit, qualified persons only, arc-flash and shock PPE and boundaries, insulated tools, and the strict energized-work controls. Energized termination is done only when de-energization is genuinely infeasible and under the full energized-work controls. (These follow the electrical-work fundamentals.)
Connection integrity
The terminations are torque-critical — a loose or improper termination creates high resistance, overheats, and can fail (fire, fault). The controls are landing conductors properly, torquing to specification, and verifying the connections. Connection integrity is a safety issue because of the failure mode.

| Step | Hazard | Control | Standard |
|---|---|---|---|
| Identify energy state | Unknown energized | Identify circuit and energy state | OSHA 1926.417 |
| De-energize and verify | Shock | LOTO, test for absence of voltage at point of work | OSHA 1926.417 |
| Energized work (if needed) | Shock / arc flash | Energized-work permit, qualified, arc-flash/shock PPE | NFPA 70E |
| Land conductors | Shock / connection | Work de-energized, proper landing | OSHA 1926.403 |
| Torque terminations | Connection failure | Torque to spec, verify connections | NEC 110.14 |
| Re-energize | Energization | Controlled re-energization, qualified work | OSHA 1926.417 |
De-energize, lock out, and verify
The defining control in an Electrical Termination JHA is to de-energize, lock out, and verify, because the entire hazard turns on the energy state. Terminating de-energized conductors that have been verified dead is relatively low-hazard; terminating energized conductors, or conductors unexpectedly energized, risks shock and arc flash. So the conductors and equipment are de-energized, locked out, and tested for absence of voltage at the point of work before terminating, the correct circuit is confirmed isolated, and no conductor is assumed dead. Where de-energization is genuinely infeasible, energized work proceeds only under the full energized-work program with arc-flash PPE. A JHA built on de-energizing, locking out, and verifying — making the work dead and proving it — addresses the hazard that defines electrical termination.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, electrical termination is fundamentally a question of energy state, and the injuries happen when conductors thought to be dead are energized. The control that prevents this is simple and absolute: de-energize the circuit, lock it out, and test for absence of voltage at the point of work before terminating — verifying it is dead with a tested meter, confirming the correct circuit is isolated, and never assuming a conductor is dead. Most termination work can and should be done de-energized, and when it is, verified by testing, it is relatively low-hazard. The fatalities come from terminating a conductor that was supposed to be dead but was not, because it was not locked out and verified.
The arc-flash hazard is the other serious one, and it is highest at panels, switchgear, and MCCs where fault energy is high. De-energizing eliminates the arc-flash hazard; where energized work near the equipment is genuinely unavoidable, it is done only under the energized-work program with arc-flash analysis, boundaries, and arc-rated PPE by qualified workers. On the projects I have run, energized termination is a last resort, not a convenience. A specific quality point: the terminations are torque-critical, because a loose termination creates high resistance, overheats, and can fail — so they are torqued to specification and verified. The JHA built on de-energizing, locking out, and verifying is the one that protects the termination crew.
The bottom line
An Electrical Termination JHA names the shock, the arc-flash, and the energized-work hazards with specific controls — de-energizing, locking out, and testing for absence of voltage before terminating (the fundamental control), the energized-work program with arc-flash PPE only where de-energization is genuinely infeasible, and proper torqued connections. The energy state defines the hazard. The JHA built on de-energize, lock out, and verify is the one that protects the crew.
Frequently asked questions
Why does the energy state define the termination hazard?
If the conductors and equipment are de-energized and verified dead, terminating them is relatively low-hazard; if they are energized or unexpectedly energized, the shock and arc-flash hazards are serious and potentially fatal. The work is de-energized, locked out, and tested for absence of voltage whenever possible, because the entire hazard turns on whether the conductors are live.
What is the verification step in termination?
Before terminating, the circuit is de-energized and locked out, and absence of voltage is tested at the point of work with a tested meter — verifying it is dead, confirming the correct circuit is isolated, and not assuming a conductor is dead. This verification is the control that prevents the fatalities from terminating conductors thought to be dead but actually energized.
When is energized termination justified?
Only when de-energization is genuinely infeasible — energized termination is a last resort, not a convenience. It proceeds under the full energized-work program: justification and a permit, qualified persons only, arc-flash and shock PPE and boundaries, and insulated tools.
Why are terminations torque-critical?
A loose or improper termination creates high resistance, overheats, and can fail (fire, fault) under load. The terminations are torqued to specification and the connections verified, because connection integrity is a safety issue with a fire/fault failure mode.
