Just ran across this Home Depot listing for this Klien linesmans that is rated for 1000v! Does that mean this tool will withstand stripping wire hot as long as it is under 1000v?
No: That means that insulated tools with that rating are must be used if you're working within the Restricted Approach Boundary of an exposed current-carrying conductor, even if you're wearing insulating gloves and other arc-rated PPE. See NFPA 70E-2019, Art. 130.7(D)(1).
If you will be working within the Limited Approach Boundary (3 ft. 6 in. at 301V to 1kV) you must have an Energized Electrical Work Permit, only allowed if the equipment must be energized for testing, or de-energizing would introduce new hazards or result in increased risk, or de-energizing is infeasible because of equipment design or operational limitations. You must use insulated tools if you'll be working within the Restricted Approach Boundary (301V-1kV, 1 ft.).
Does that mean the tool can withstand a short? No. It means the likelihood of a short is less, because much of the tool is insulated, and the hand holding the tool wouldn't get a shock (remember, you'll be wearing insulating gloves, too). So yes, the tool will be still be fried in the unlikely event of a short.
