1. Resistance (R) = Line to neutral voltage (V) / Rated current (I) - Tolerance : ±10 percent

2. Power frequency withstand test(One minute)

-Rated 600V or less : <2 X Line voltage> + 1000V

-Rated over 600V : <2.25 X Line voltage> + 2000V

3. Listed neutral grounding resistors are designed, tested, and rated in accordance with ANSI/IEEE

Std 32-1972 (Reaffirmed 1990).
