When conducting an arc flash risk assessment in accordance with 130.5, the 'condition of maintenance' is not a consideration.

• A. True
• B. False
• C. Not specified
• D. Only for certain equipment

Answer: (B)

The main idea is that arc flash risk assessments must reflect real-world conditions, including how well the equipment is maintained. The condition of maintenance is not something to overlook because how a device has been cared for can change the hazard you face. Poor maintenance can lead to degraded insulation, loose or corroded connections, or worn protective devices, all of which can increase the chance of an arcing fault or lengthen the arc duration. Longer, more energetic arcs mean higher incident energy and a broader arc flash boundary, which directly affects the PPE and procedures you choose for the task. So maintenance status is a valid factor to consider in determining the actual arc flash risk, not something to ignore or limit to only certain equipment. Ignoring it could underestimate hazards and leave workers underprotected.
