*Avoid contact.
Distances agree with OSHA guidelines in Table R-6 of the Federal Register published 1/31/94.
These distances take into consideration the highest switching surge an employee will be exposed to on any system with air as the insulating medium and the maximum voltages shown.
The clear live-line tool distance shall equal or exceed the values for the indicated voltage ranges.
