Insulating Gloves and Sleeves Insulating gloves and sleeves are critical PPE for electrical work on or near exposed energized parts. The 269 standard (1910.269(l)(2)(i) and (l)(3)) requires that: Additionally, 1910.137 provides specific design, care, and use requirements for rubber electrical protective equipment. Insulating gloves and sleeves must be rated for the voltage to which a worker will be exposed (phase to ground or phase to phase) and marked to indicate their rating. 1910.137 recognizes Class 0 (up to 1KV) through Class 4 (up to 36KV) rubber equipment. [See Mr. Edwin Hill Interpretation Letter (September 27, 2005)].
in conductor / over-current protection device ratings. When installing a TVSS device on service entrance panels with large current ratings the 1/10 tap requirement may mean that the correct tap conductor size exceeds the capacity of the TVSSâ s terminals. Under such conditions, a circuit breaker is usually required at the point at which the tap conductor connects to the primary supply. The size of this breaker should be chosen to accommodate the size of the tap conductor rating. While such a measure provides safety and compliance with the tap rule, it also add cost, complexity, and the introduction of extra series components which may
