How often must live line tools be removed from service?

Explanation:
Live-line tools must be removed from service on a two-year cycle to verify their insulation integrity. Over time insulation can deteriorate from aging, moisture, cracks, or damage that isn’t always visible, so periodic removal allows a thorough visual inspection, cleaning, and dielectric testing to ensure the tool is safe for use on energized lines. If any damage is found or the tool fails the dielectric test, it must be retired or repaired before reuse. Shorter intervals would be more protective but impractical, while longer intervals increase the risk of undetected insulation faults.
