Verified 2026-10-27 Confidence: High

Table 130.5(C)(3) of NFPA 70E-2027 estimates the likelihood of an arc flash occurrence by task; the tasks it lists include operating a circuit breaker or switch, the first operation after installation or maintenance, and racking circuit breakers, and the equipment's normal or abnormal operating condition changes the estimate for several of them.
